Need suggestions:

FT TC4 On a 90 foot oval. So we are small. I have a few of the new STOCK CO27 motors.

I need suggestions for Spur/Pinion, and color tires. I use Green on front and rear outside, and Orange/purple on inside front rear. I have the final race for points this weekend. I am 1st in sedan and want to win. I got second last week, I just didnt have the power.

Thanks in advance everyone!

Your car's top speed should be at 3/4 the way down the straightway or just before you have to back off for a corner.

to achieve this would you go with a larger spur and smaller pinion or smaller spur and larger pinion.

Currently I run a 72 spur and 20-22 pinion or so. According to robinsonracing.com my ratio is
20T 3.60-1
21T 3.42-1
22T 3.27-1
