Modeled the gearbox in LDD! File will be available here soon. In the meantime, I'm struggling to find a good seat design that's mostly studless. Any suggestions? (P.S. Anyone notice the new logo?)

It's actually the DTM version of the car:

You got it!

Added a gearbox with a realistic (albeit long) shift lever. Also trying out some wheel covers, not sure if I quite like them. Oh, any guesses as to what car this is? Hint: It's German.

The model I'm basing this car on actually uses a V8 engine, was originally gonna make a V10 car. MOCs don't have to be V8. ;) The reason I'm not using suspension is the bodywork: it's going to be very, very low.

Signs of life have appeared at the VKTechnic desk...

What I'd like to see is a sped-up version of you making these parts, using a screen capture software.

EDIT: This is a WIP thread. With the Mustang project on hold, I've spent some time looking at Kevin Clague's Brickshelf folder and was inspired to build a hexapod. Like his models, I hope to make this fully mechanical i.e. powered only by one central motor. Here is the first step, a (simple) timer based on two driving rings. This timer still needs some work, as the driving rings offer quite a bit of slack (this offsets the timer sometimes). Next version will not have driving rings.

I see you really like Russian trucks. Keep up the great work!

For a leaf spring? There's no mounting point for the axle... Do you have a picture of a setup using those?

Love the bodywork!

That's a pretty interesting idea...I'm going to a hobby store today so I'll see what they have to offer. Thanks for the suggestion

If anyone's wondering what happened to the car, I've been at a creative roadblock this past week. This is partially due to breaking both leafsprings (one while drilling holes, one on the chassis): I did start working on the rear end, but nothing I'm too happy with. I will try changing the bodywork color to black (not too motivated to build a full body in LDD and then order parts). If that doesn't work out, I'll end up moving to another build.

What is that purple thing on the side of the differential?

Got my leaf springs printed today! Just a little cleanup needed (one edge sanded and a hole expanded slightly). Installing these tonight and working on the rear end this weekend.

Yes, that is a dashboard. Thanks for pointing that out, I'll redo the leaf spring mounts tonight.

Progress has been done! I removed the engine scoop and started working on the front end. Plus I installed a working steering wheel. Random facts: The car has Ackerman steering geometry, and the front shocks are mounted to the top wishbones (for accuracy, of course).

Yep, using hockey spring, Yep, just one. The drivetrain is really simple, so I don't need much power. I tried 16L axles, and I didn't really like them either. There isn't a good way to mount them without the axles moving around.

It's actually part 60208 -- There isn't a lip on the wheel.

I built a mock-up leaf spring setup and I found it to be too stiff for the model I'm building. Plus, mounting them is a little awkward, as I don't have the 1x4 lightsaber pieces. For now, though, here's a chassis with the mock-up springs: I redesigned the rear axle as well, so that the axle is as close to the spring as possible. Here's a picture of the axle alone:

Another problem I didn't mention with flex axles is the fact that they move side to side. With real-life leaf springs, the axles don't need linkages because the leaf springs only provide motion up and down. If I were to use flex axles, I'd need extra linkages, and they will only act as a shock absorber. Same with the idea posed by Hrafn: the rear axle would have no stability with forward-backward movement.

Sorry for the lack of updates, I've been a tad busy. Anyways, the rear axle has been completed: Unfortunately, LEGO bricks don't bend well enough to make good leaf springs. I tried 1x12 plates as well as 1x16 axles, and neither of those bend enough to make a soft suspension. On the other hand, flex axles are too soft to support the final model's weight. Thus, I developed some 3rd party leaf springs in Autodesk Inventor: These will be printed some time next week, but for now, I'll make some mock-ups and get working on the chassis.

Looking good, keep it up! I wish there was a way to 3D print tires...

Dang, that's really good!

Yep, same wheels. Got that from your video on A-arm suspensions
