Im using a 78tooth Losi spur on mine - for motor position. Any smaller and I can't mesh the pinion.

Im on 78/23 on a 5.5 Speed Passion.

I am using the car as standard, I felt the driveshaft angle locked the shocks on power not allowing them to absorb bumps - felt very skitty to me... I tried several ways of doing it, and it was at no point better than the std mounting position.
