Suspension is pretty fragile on hard bumps, brakes are very good, looks awesome (maybe bonnet pins and exhaust tip should be bigger). I think you should definitely change gearbox for paddle shift- like real "WRC+" cars. It changing direction really quick- bigger steering angle makes difference- maybe its good direction- not like hardcore real but feels good. Caster is so big like hardcore RWD cars, driveshafts has hard time in this π
In our "Rally2" car tires are shit top, but what do you think for using narrower slick tires?
