What do you guys think about some of the aluminum upgrades. I notice a lot of people like RPM. I wanted to strengthen my Jato, and dont know where to start. Also, what dou you guys think about the aluminum c hubs and such. I dont know the names of all the parts, but you guys know whats out there. I broke my rear arms in half, and want something a little more durable. Aluminum? or RPM? what about RPM arms, with aluminum hubs?
