Im considering getting the HR race springs.. but I was concerned w/ the ride quality. I know its going to be stiffer.. but is it a terrible ride? ie. like those "slammed" hondas that bounce? Also, does the undercarriage scrape? I really want to avoid that. I already have the sport package suspension on my 328i, so I don't plan on changing my shocks. I just want to lower the gap between the fender and my 18" rims. Thanks!
