hey i got a 92 h23 with adjustable coilovers from a local parts distributor and its their own brand. its called maxspeed. anyways i stiffened them so that when i went over speedbumps the car wouldnt bounce and hit the bump. but now they squeak alot when i brake. i tried loosening them half as much as i tightened them but it began to bounce on bumps again. how do i make it stiff without the squeak?
