Ok so my car is a Traxxas Rustler VXL and I know I need a 32 pinion gear and 76 spur gear with a lipo battery, already have the battery, in order to achieve 70+ mph. I am tying to find where I can buy it online. I am new to RC Cars by the way. I think I might have found both of them on Ebay. Can you guys tell me if these are the right parts or not in order to get the car to go 70+mph?
