well i installed the hks hiper d coilovers and i have a few questions for the people who are using this or know about suspension. this is on a fc completely stock even stock wheels and i also have the coilover height around stock. well the car feels a bit tighter but it feels bouncy especially when i have the rear at the stiffest setting possible. i just hate that bouncy feeling...what can i do to get rid of this?

 

Have you checked that the springs are working well?
