whats up everyone, I just got my M05 together, i run on high traction carpet.

I want to know what tamiya tires would work best/.

and what do you put in the gear diff? I used 100k and the car pushes off power & spins the wheels if i slow down prior to the turn & power out

I know i am losing time & we have a cahs race this weekend & i want to win some $$$

Thanks guys/gals
