Vasilis and Bobskype have been working on making a 125cc Shifter Kart for AC. The mesh is very early in it's stages, but Bobsype's been working on the physics quite a bit. The suspension is solid, since in real life these don't even have suspensions. So all of the tuning has been put into the tires.
I've been helping Bobskype pushing the physics more, it is still in early stages, and will be updated now and then as often as we can.
It now uses a 6speed paddle shifter gearbox (thanks to mclarenf1papa) without autoblip.
I'd personally advise running drift tracks with it, its a huge fun on those narrow winding tracks
(be sure to check if the grip isn't 1.0 in surface.ini of the track you'll choose)
v0.05 : tire model updated, suspension updated, paddle shifter.
3d - Vasilis
Physics : Bobskype and myself, with some help from Mclarenf1papa.
