The bouncing is a problem with the race springs, which is effectively eliminated with better aftermarket shocks.

The ride with the H&R sports is slightly more stiff than stock ZSP, but along with that comes tighter handling. Coilovers offer adjustability of ride height and dampening, and are usually more comfortable than the springs only route, but cost more.
