rear springs are bouncy AF! anyway to adjust the rear ? or anyway to get stiffer spring rates?


another problem, the rear shocks makes a noise as if they're rattling when I'm drive on bumpy surfaces . anyone know why?

 

make sure everything was tightened when the car was on the ground.

If everything is tight, perhaps its time to call Ksport or D2 for new rear shocks

 

KSports bouncy?



I don't think i've rode in a car with KSports that wasn't bouncy. I don't think their dampers are up to the spring rates they sometimes ship with. If anything you should get SOFTER springs so the dampers can keep up with them. Springs are supposed to be bouncy, dampers are supposed to control that bounce.

Do the KSports for Fits have damping adjustment?
