One of my first cars was a Rustler, since sold and now have a pede. Bashing I say, RPM bumper, bearing carriers(front and rear), I love the older 19 turn Trinity Quartz, loads of low end, but they are a rare find since being replaced by the Arcornite, but something like a 17 turn will be very good with the stock speedo. I never had a problem with the trannys at all, even running a 10x1 with a 7 cell pack back in the day. I did do the MIP CVD replacement, but before that I had the steel drive yokes, and those were overly built for my truck. Biggest thing I always had a problem with was the shock caps popping off. Solved with a set of AE off a RC10 and RC10T. I would say get the Traxxas Big Bore aluminum or AE rear truck and front truck set. Only other thing is tires, but that would depends you are driving on.
It is one hell of a tough truck, with very few problems. Mine was the fastest on the block with the power I had going through it. The ting is built like a tank so not much you can do to end. Just Lipo it, and a better motor.
