Wheel hop?
 

For some weird reason my rex is getting wheel hop? My friend doesnt get wheel hop when he launches but i do. Even if i want to do a burnout i get it. The car only has a streetported 12A and its getting hop? Its really getting me mad because it messes up my launches and wheel hop breaks stuff. What do you guys thinks it is?

bushings in your rear links and/or tire compound.

Bushing Slop = Wheel Hop!!

On that note, what is your suspension setup?

First thing I would do is compare all of the rear suspension components between the 2 cars and see what's different between the two. It could be anything from tires, tire pressure, shocks, springs, bushings, diff, clutch etc..

well he does have different shocks then mine. The last over changed them. He has the same rear tires and me(sigma?) springs and bushing are the same.we have the same clutch( just a stock replacement and both of our flywheels are resurfaced. Should i get a whole polyurethane kit for the car? That would probely help some what right?
