Im going to do my balancer this weekend so i figured i might as well swap some pullies since one will be off already and ill have to remove the fan and maybe the radiator for the extra clearance. So which pullies should i go with? I was looking at either FRPP, ASP, or March. Who has the best quality? And where should i get them from? I was looking at thunder racing and they had descriptions that said 26% crank and 30% water pump, what does that mean?
