almost any kinds of mods you do to the revo will make it better. My personal favorite mod is the os .18 motor. The 2.5 worked great for me and i rarely had problems but the os has a ton more speed, and seems to have the best power curve for the revo. Either the os or lunsford parts are my favorite. Everything after that is still just getting a good setup you like. And i wouldnt get any aluminum arms unless you want a really heavy truck.
