Jimmy, thats the setup I am using now and prefer 35t all round. Its easier to drive on high and low grip surfaces.
When you have no motor attached in the car, how far does yours run when you push it? Daft question I know but with all my other cars (all four of them) they ran very very freely whereas this thing feels that there is a brake on. The belts are free and the bearings are fine. Is there any zero angle available for the car ?

I've run the equal pulleys yeah - I actually raced at the Euros last year with 35t black pulleys front and rear. The car is surprisingly more stable and easy to drive on loose surfaces with the un-equal overdrive setup tho. On high grip you might not notice any difference between the two.
