I have 2 friends that have AC 500's one is a few years old, & one is new... these guy's just came back from the Glamis sand dunes... both hungry for more power / acceleration... has anyone got some suggestions for clutch springs or any other reasonable mods these guys can do to help them up "competition hill" ???

 

500 what?

year model?

Make?

current mods?

goals?

current power?

these play a big role in answering your questions


good luck
