What is the track like? Gear for the track and not per someone's recommendation who never saw your track, driving style and surface.
Try rollouts in the 60 to 70mm range for small technical tracks.
At the track I race at it's a 75'x35' track with a lot of infield. I'm using a Tekin 13.5/RS v203. Tires are 45mm, spur=80T and pinion=38T for a rollout of 73mm.
Rollout of 80+ will be more for a very large sweeping track.
Temp your motor after you finish a heat and gear so you do not exceed 160*F. (Some motors are good to higher temps but 160 seems to be universal.)
