i recently bought a tt01 tamiya car, and wanted to buy some upgrades. so i listed some parts, ballraces, alu shaft, motor etc. but im stuck on which motor to buy. can anyone tell me the difference between the tamiya super stock motor TZ and the super stock motor RZ? i read somewhere its something to do with torque and RPM but it wasnt clear (and you guys are pros) thanks in advance
also what are the best (reccomended) upgrades for the tt01
