I've been racing 1/12 for over 25 years, tire care is one of the most important steps in ANY race car big or small. Me? I prefer foam, I find them the easiest to maintain. as far as set up its all important. It seems to me everyone wants to fix something that's not broken. I don't race tc so its whatever the racers want to do and the people pushing for rubber in 1/12 don't even race it. Just like the guys pushing for 2s in 1/12 says that's what we needed to get more racers. I figured if a $25-40 voltage booster was stopping you, you really weren't interested anyways. Will foams bring me back to tc? No but I might play with one.
