1. Concept car of Nathanael Kuipers: After building a lot of supercars i would second this one - not the most features, not the most oustanding never seen feature but IMHO one of the best (if not THE best) building experience i ever had - Nathanel has IMHO the most elegant and professional building style (this incl. all TLG-designer!) - a cit. of Antoine Saint-Excupery probably describes it best: "Perfection obviously does not arise, If you have nothing to add, but when you can not take anything away". - and this is the style of Nathanael - you have always the feeling that really each part he has used is the best possible solution and exactly this part MUST be used here - and there is no part too much - can not describe it better... Here is thre EB-topic for this car and my praising: Just see this pic and you know what i mean - it's quite jaw dropping when you see the gearbox-module smoothly falling into its place.... There is also a convertible variant of this car: So even this car is quite old and even there are some other very good supercars out there i would still rate this one - together with the following Predator (s.b.) - as the best - or the primus inter pares... 1. Predator of Nathanael Kuipers: The Predator of Nathanael is also in my Top-3 ranking and on par with the concept car: a really unique and nifty gearbox, a top of the notch front-axle layout, a very realistic sport-car layout with engine in front of rear axle and transmission behind rear axle (as many real cars), wich is AFAIK quite unique for lego supercars and really very well done panneling - and of course again an exellent building experience, a real pleasure to put together: http://rebrickable.com/mocs/MOC-2811/NKubate/predator-supercar/ - But "an exellent building experience, a real pleasure to put togehter" is valid for all of Nathanaels models. Here a two very well elaborated reviews of this model: https://rebrickable.com/blog/94/review-nathanael-kuipers-predator-supercar-moc/ 3. Porsche 42056 by Lego and modded by @Didumos69, @jb70 and @DayWalker: And not to forget the Porsche 42056 but not in the retail version but in a highly improved version: http://rebrickable.com/mocs/MOC-8003/jb70/42056-pimp-up-my-porsche/ The following two MODs added to this Porsche package and you get IMHO a gorgeous looking model which greatly resembles the real car, with cool and reliable working mechanics, a cool gearbox, a stiff chassis, a quite modular build and a really great building experiance... Summary So currently these three cars (Concept car, Predator and Porsche GT3RS 42056 MOD) are my Top-3 of supercars because IMHO all of them are on TLG-level concerning rigidity, robustness, building style and all of them have something outstanding and unique - but i have to admit: i have not build the Scorpion of Paul Boratko (crowkiller), the BMW 328 Hommage of Jeroen Ottens and the Hammerhead of Didumos69 but they are on my next Todo-list... and i have high hopes for all of them: Could be that i have to re-rank my current Top-3 of supercars - well, we will see ;-) For my whole posting please have in mind: It is just IMHO! PS: of course there are some more very well designed supercars of not mentioned builders out there which are of course very good too and absolutely worth of building (e.g. Simple supercar of Lipko which looks also gorgeous and has a typical Lipko-style stiffness ;-) PPS: i have intentionally not mentioned the gorgeous looking and also excellent designed models of Madoca because his models are IMHO not supercars in the original sense of this term - mostly because they are all missing a gearbox...

Didumos69, why do you still think, that it is possible to switch to neutral when in 4th gear? This is not possible, see above bullet b: " b) engaging reverse (or neutral) mode is not possible if another gear than 1st is engaged, ie. it does NOT allow to shift from 4th (and also not from 3rd and 2nd) gear to neutral and back"... If you have a deep look at the solution of DayWalker which i built then you will see, that moving from D to N moves the 3L driving ring 1/2 stud - but this movement (even just a half stud) is not possible when in another gear then 1st - take a look at the following pics: In the following pic you see a "zoom" into the preventing-module: The 3L driving ring drives a slider which slides an axle through the pinhole P (see small pic above). In D (real D not sticker D) the mode stick is in back position which means the driving ring is in most forward postition which means the slider axle in pinhole P ends exactly in P, ie. the axle does not protrude into the H-frame. When moving to mode neutral the drivingring moves by 1/2 stud which in turn moves also the axle through pinhole P 1/2 stud (moving in reverse mode moves the driving another 1/2 stud so overall 1 stud --> in mode neutral the slider axle protrudes 1/2 stud into the H-frame, in reverse mode it protrudes 1 stud into the H-frame. No take a look at the yellow-DBG "knob" (on the right side of the small pic above). This knob "opens" pinhole P only in 1st gear, i all other three gears (2nd, 3rd and 4th) pinhole p is closed so thr slider axle can not protrude into the H-frame, not even 1/2 stud.... therefore you can not switch to neutral in 4th gear! But only if you are in 1st gear. Therefore this solution is IMHO complete, means it fullfils ALL requirements. Was my description unstandable?

as for the wrong console stickers: yes, very annoying - probably TLG did this because for kids it's more intuitive when driving forward means pushing the lever forward too and reverse means pulling the lever backwards... but for an ultimate model for a target group 16+ it's a shame... i asked already Walter (the guy who sells some really cool door and rear spoiler stickers, see ) if it would be possible to produce and sell custom made console stickers with correct R-N-D sequence but he said this would be too expensive... but he adviced me, that some cutting and reordering of the official console sticker could do the job: ordering a new sticker set, cutting the left console sticker in pieces so we get parts where we can exchange D and R in its positions - would be quite fiddling but i asume the cuts would be hardly noticable... so i will give it a try... but also if sticker cutting does not work i will stay with Daywalkers reverse gear MOD simply because it is right - sequential gearboxes have D backwards and R forward, period! ;-) Look, we can not discuss that the front calipers must not be mounted on the front side of the front-axle just because the real car has it at the rear side and simultansously accepting that engaging reverse needs pulling the mode-stick backwards...

Hmm, in the meanwhile i would say, it is not the best to bypass the complete gearbox for reverse because this alone would not prevent from shifting from 4th gear to neutral or reverse - Appie has implemented such a bypass and with such a solution you can engage neutral or reverse mode whenever you want regardless of the gear currently active. Therefore IMHO the only way to make the gearbox behavior realistic is a solution like Daywalkers. IMHO the latest one (see some posts above) fullfils all requirements: a) reverse gear has a high reduction-ratio (in this case the same as first gear) b) engaging reverse (or neutral) mode is not possible if another gear than 1st is engaged, ie. it does NOT allow to shift from 4th (and also not from 3rd and 2nd) gear to neutral and back c) in reverse mode you can not switch gears - so in reverse-mode you HAVE JUST ONE possible gear-ratio (see a) Have i something overseen or do you agree, @Didumos69? if yes, then IMHO this solution really deserves being integrated in a ultimate Porsche ;-) @Didumos69: Thanks you very much - just had a look at the photo sequence - very easy to follow, thnak you. also for the installation-notes - i definitely will gives this unit a try - even though i'm quite satisfied with the stock paddle-shifter because in combination with your ingenious 90 degree indexer (and the other optimisations of your errata/jb70's package) the shifting works 100% reliable and smooth for me...

@AppieYesterday i had in mind, that it would be a good idea to combine both reverse-gear MODs - yours and daywalkers: yours for the additonal gear-train for reverse (as in real cars) and daywalkers for the prevention from engaging reverse when others gears than 1st are engaged (as in real cars too)...but after a little bit of thinking about your solution, Appie, i now think, that this is a bad idea, at least, if one is not a real hell-driver as you, Appie ... Well, lets have a closer look: you wrote that with your solution "reverse gear has the same ratio than 1st gear"... well, IMHO this is wrong - but let us first check some facts - see following pic: This is the retail gearbox-layout which has the following gear-ratios and -sequence as shown in the pic above (at least if you have fixed the wrong gear-sequences by Borratkos fix). The green arrow means that this red clutch gear is engaged for the named gear. x:y means: if pistons spinn x-times, then the 20th black bevel gear nearby the differential spinns y-times. Do we agree about this? Do you use this or a equivalent gear-layout (BTW: the layout of Didumos69 and jp70 has the same ratios and gear-sequence)? And do we also agree that your reverse-gear-axle at the bottom connects to the DBG 24th gear of the gearbox (see second pic of the quoted post)? If three times "yes" and if i have nothing misunderstood (which is always possible in my case ;-) than your reverse gear has not the same ratio as first gear (as needed) but the same ratio as the 4. gear, ie. 1:3, which is the highest gear which drives the car drive fast... To cut a long story short: Your reverse gear is a quite fast and special reverse gear, one could call it an "overdrive" ;-) and you must have really excellent driving skills for parking backwards

i take it very easy - no worries - and i also like your reverse-gear-MOD a lot (in generall it is a very clean solution) but - as written above - i prefer that one of DayWalker for certain arguments... and i can not imagine from your description how a solution for the mode-gearbox based on 6L thin liftarms can be as rigid as the current one with 5L because the 5L liftarms have axle-holes at both ends which brings a lot of rigidity into the game whereas the 6L just have pin-holes which are IMHO less suitable here... but maybe i have just not understood what you have in mind... probably i haven't understood it... ;-)

@Appie: they are incompatible! Reason: for the gear indicator the mounting of the LBG vertical thin liftarms of the mode gearbox to the LBG baseframe has to be changed: the left perpendicular connectors (see pic below) have to be moved to the middle pinhole of the frame to make place for the gearrack. So the middle pinhole of the frame is blocked by a black 2L pin - and this is the pinhole where your MOD routes the new axle which passes the gearbox.... see the following pic: And i see no easy and robust way to reserve this middle pinhole for your MOD if the gear indicator of DayWalker should be applied...of course one can combine your MOD and this gear-ndicator but this would require a complete redesign of the mode-gearbox-module and its mounting to the chassis - at least IMHO... In general and in real life i would agree with you but not for the Lego Porsche model: because the body hides completely all mechanics you can only demonstrate the features without body (therefore the removable body MOD). And therefore especially THIS chassis has to be as rigid as possible also without body... and - at least IMHO - it is good supercar buildingstyle to design a Lego chassis with best possible rigidity for itself: most Lego bodys i saw until now are way to fragile - or if not fragile then at least far away from being stiff enough (especially the very important A-frame of the windscreen is really without any stiffness in the bodies of lego supercars) to serve as a serious rigidity-factor for the complete car...

for which purpose? ah, i see, you mean for the mounting of the gearrack to the hub, right? Well, i was not sure if there are axle-towballs... and i wanted to use as much as possible of the parts of 42056... but of course you are right: with a thin 1x2 liftarm and an axle towball you can mount the calipers also on the rear side of the front-axle - but does this really matter? AFAIK one side is as good as the other, isn't it? ;-)

another small enhancement, now related to @jb70"Pimp up my Porsche"-package: In this version the fron yellow calipers are mounted at the rear side of the front-axle - and because at this side there is also the gearrack with Ackerman-geometry mounted the calipers have to be mounted half a stud more below - but now the calipers rub quite strong at the front-rims so the car does not roll freely when you push it... my solution: just mount the calipers on the other side, ie. at the front-side of the front-axle - there is a free mounting point on the hub so the calipers can be build and mounted just as in the retail BI of the retail Porsche - two pics of the modified (compared to the BI of jb70!) calipers and the modified gearrack-hub-mounting: new caliper mounting at the front-axle: Mounting of the gearrack to the hub: Both changes are quite obvious but i thought i report them here so the ultimate pimped porsche comes closer ;-) With this changes now nothing prevents anymore the Porsche from rolling absolute freely when pushed by hand with a strong impetus - even in 1st gear - kudos to Didumos69 and his pimped drivetrain of his errata (contained in jb70 BI-package)

Didumos69, i would be very interested in this photo-sequence - thanks a lot in advance!

well, normaly i always ensure that an axle is beared at least by two pinholes... but in this case - the complete axle (two axles and 1 u-joint) is guided by two pinholes - there is in fact zero torque to be transmitted - the axle spins very slowly - pins with pinhole stick very firmly in a pinhole so alltogether the solution is exactly as robust as it has to be here... well, if you would like to change gears by turning the blue indicator we would need a much more secured and beared solution - but we don't want this ;-)

@DayWalkerKudos to you and both your MODs: The gear indicator and the prevention from having 4 reverse gears. I have now both integrated in my Porsche (built the wonderful package "Pimp up your Porsche" by @jb70 - which i have already praised some posts above) - both your MODs can be very easily integrated in jb70's Porsche implementation! The few needed changes are very obvious and easy to manage.But one remark: Especially the gear-indicator MOD can not be build in the already built model - for this mode you have to go to the beginning because the mode-gearbox has to be dismantled and has to be mounted differently to the LBG bottom frame. Both MODs are so well integrated into the mid console so they are invisible after applying the black curved panels: (I will replace the 4 yellow half bushes of the paddles with blue ones so indicator and paddle have the same color - unfortunatelly the exist no yellow 1x2 liftarms thin). Side of the gear-Indicator - only the black 20th bevel gear is visible (and of course the blue indicator at the dashboard ;-): Side of the prevents from having 4 reverse gears-MOD: A remark to this MOD: Overall i prefer DayWalkers's solution to that one from Appie because (a) it is more realistic (because it prevents from engaging reverse or normal mode if another gear than 1st one is engaged - which is as in the real cars) - with Appies solution you can engage reverse/normal-mode regardless of the current engaged gear. And (b) DayWalkers solution can be combined with his gear-indicator-MOD (Appies solution can not be combined with DayWalkers gear-indicator-MOD!) which is IMHO quite essential for a sequential gearbox: the driver (and of course also the HoG-driver ;-) of a car should/must always know which gear is currently engaged - and in case of a sequential gearbox this is quite impossible without a proper gear-indicator - and this feature-lack is eliminated in quite an optimal manner by DayWalkers's solution - Kudos to you, DayWalker, works like a charm and is a very clean and robust implementation. Summary: The gear-indicator MOD is IMHO a Must-have-MOD and the preventing-from-having-4-reverse-gears MOD adds really realism value to the model and is also very well implemented - both can be combined very well and can also be integrated very easily into jb70's Porsche-package --> Strong recommendation! @DayWalker i have made just very few and slight changes compared to your implementation - the most prominent one is the bearing and mounting of the vertical gear-indicator-axle - see following pics: You see i have used a 3x5 liftarm (which is also used as bearing for the reverse-gear-slider) and some pins-with-pinhole instead of your triangle-solution. Reason: with the triangle-solution the black Liftarm 1 x 2 Thick with Pin Hole and Axle Hole (mounted at the front of the gearrack) can slightly (very slightly) collide in 4th gear with the triangles (even when using the modern version) which in turn could result in some stress for the indexer-module of Didumos69. With my solution this is impossible and works in all gears without any collision and stress.

@Elvis2500: If you don't mind and if you don't be annoyed about: - way to weak front suspension which hardly can hold the model 1 stud above ground and which hardly come back if you press it down - somehow medicre gear switching mechanism which is not very reliable, means often the next gear does not lock in correctly so the whole drive-train stalls - bad playability cause of the missing HoG (hand of God) for easy steering because the inner driving wheel is hardly accessible for a male hand - you can not see the inner goodies because the porsche shell covers all so all mechanisms are quite invisible So if all these pitfalls are no problem for you and if your model is just for a beauty display then the retail model 42056 is of course "passable"... But i would strongly recommend you to build this: it contains all of @Didumos69 errata and much more - it is IMHO easily the best and easiest deal to get a full and reliable working Porsche for only small additional money and with full blown step-by-step PDF-Instructions for free.

ah, i'm a fool - i have already applied the body-removal MOD so i could find this solution for myself if i would have switch on my brain ;-) Thanks for your fast reply! Another question: cause of the driving axle for the gear rack now the DBG part of the CV-joint (which connects to the paddleshifting unit) can not be mounted anymore ... Have you replaced the two CV-joints by two U-joints?

@DayWalker Just implemented yur gear-indicator in a dummy-test-chassis (excerpt) and it works like a charm - but i'm wondering how you have mounted the driver seat - because the 12th tan bevel gear (which drives the 20th gear which in turn drives the gear rack) colides with the standard mounting point of the drives seat (a LBG 2x4 Liftarm thick)... could you please post a pic how yoz changed the driver seat mounting? Thanks a lot!

@8421XXL Walter, really great sticker sets - i will contacting you for ordering - but first a suggestion/question/plea: Unfortunatelly the D-N-R sticker should be reverse, means R-N-D as in all real cars and therefore also in the real Porsche GT3RS... Would it be possible and may i ask you if you would like to make and sell such a sticker, ie. the same as the retail mid-console sticker but just R and D exchanged? This would be great and i would immediately ordering ;-) Anyway: Thanks again für the great GT3RS-Door stickers! Kudos!

Just built this "Pimp up my Porsche" from @jb70 - very enjoyable build, great instructions (errorfree), incorporates all essential MODs you need to change the somehow mediocre retail 42056 in a really great set, now also functionwise: - stronger front suspension (retail is much too weak) with much better geometry with less bump steer und Ackerman - also better steering lock - oustanding indexer so now gear-switching is now 100% reliable, so NO gearbox stalling anymore - fixiert step-5 erfror in the BI and in Addition much better gear-arrangement in the gearbox for frictionless spinning of all gears - the car now runs absolute free and smooth when pushed even in 1st gear - prevetning from endless gear-sequence (ie. now you can not switch from 4 to 1 or from 1 to 4 - correct gear-sequence - reinforced chassis so the chassis does not bend even without body - HoG (essential for playablity) - removeable body (essential for demonstration all the goodies) This means all fixes from the errata of Didumos69 are apllied and in addition some important stuff from his ultimate playable Porsche - all compiled into great PDF-instructions, even for free! Many Thanks, @Didumos69, many thanks @jb70 One recommendation: i strongly recommend not to apply the pin-connector clutch but replacing this with a simple axle 4L! Cause of the now guaranted 100% reliable gear-switching there is no clutch necessary - in contrary: it could be that the clutch slips (e.g. in reverse gear) without any danger for part damaging - without clutch all is working like a charm and the pistons just fly ;-) But this is the only change i have made - with exception of this the Porsche of jb70 is simply perfect: great to build and great to play. Kudos!

@DayWalker: May i ask you for some bigger pictures - maybe on bricksafe or somewhere else - because your solution looks really interesting too...

Your reply sound not really confident, in contrary it sounds harsh and insulted, so an oversensitive person would react - IMHO jeroen gave you very constructive critics and hints... IMHO a forum like EB is not only for praising all MOCs into heaven ... just my 2ct

Wow! Best non-Sequential-gearbox-shifter ever seen - because the most realistic one concerning driver-operation - the true successor of 8880-shifter with 5+R... this one and Didumous' sequential one are my favorites... top notch

@jb70: very good Package you have compiled - something i have waited for a long time: the full errata of Didumous enhanced with his mod of Additional shock absorber and improved ground clearance for front axle (Imho the retail Front axle is one of the most annoying pitfalls of the retail Porsche) and the Hispabrick mod for an easily removable Body.. Now even with HoG, great- this is the Porsche TLG should have released.... thanks a lot for the all inclusive PDF BI!!!

speechless - never seen a cooler MOC... may i ask you for BI? Well, just kidding...

Thank you very much in advance BusterHaus!!

Incredible project - IMHO the "best" supercar out there (as far as this can be judged just from this WIP-thread) - at least if you take into account such aspects like "having and following a story", "being unique", "having a soul" - IMHO this should be an official Lego set - it is and represents all what lego technic should be: very well done technical functions worked out in best engineering manner - can't wait to build this car!

I'm curious if i will enjoy Building this great model as much as Nat Kuipers Predator ... but what i see and what i read is very promising...especially the comments of you, Meatman... thanks again for the free BI!!
