H&R Sport Springs drop the G29 BMW Z4 roughly 1.0" front and 0.8" rear (M40i) for a tighter fender gap, a lower center of gravity, and reduced body roll. The progressive spring design firms up under cornering load while keeping ride quality comfortable on the street. This set is compatible with the factory adaptive suspension.
