@Didumos69got heavyly inspired by this MOC bougth my 1st set as an adult! 42099 instead of the zetos despite them being the same price and zetos having clearly more fun parts (but no cool wheels!).
Biggest technical change was figuring out how to route the stearing (with Ackerman geometry!) while maintaining the short length of the front axel.
Made the drive go via the middle of the turntables and improvised my own version of the front - rear synchro - a beast compared to the stock but probably has much more slack than the one you've designed :) in hindsight should re-use one of the frames to make it rigid as it is wasted on the rear suspension... But I'm to lazy to take it apart and if I play to hard with it, It just pops out a pin or 2.
Re-used the stock body - actually liked it and... I'm lazy. Can't lift by hood or trunk without some part bending but whatever :)
Really - can't state how fun of a project this was! And I got motivated only by your great design work on this one!
