The gearbox is most definitely the weakest part here. I found if you use Legacymode = 1 axles for the gears it slips a lot and has vibration issues at high speed. If you use Legacymode = 0 it gets rid of both issues but the hinges stretch a lot under large amounts of force, so the gears need to be really heavy (like 300 - 1000 density most of the time. you could probably get away with lower density here because this is a light vehicle )

Now I know this isn't yr gearbox, and you should start making your own because one gearbox won't work with every car out there

Yeah, I know. But I'm not really that techincally advanced with scripting and everything. I'll find a way.
