If you're serious about modified racing you should be rebuilding your motor at least every other run. For ANY mod with standard size brushes, I'd recommend Quasars or the trinity 4383's. Quasars will last much longer however. Personally i think the best mod out right now is the D5, but i don't know if you can get those in europe yet.
