Can any of you guys who run 17.5 (or have run it) help me out here because I need to buy a couple pinions. I will be using a LRP SXX v2 and probably a loaner Tekin motor.

Thanks!


Take pinions 28-32 to get good final drive ratio choices. I think 31 would be the go for FDR.
Feel 7 / Boost 7 if you want the edge.

Ratio = (Spur / Pinion) * 2.6(Factory FDR)

Cheers
