H&R Sport Springs for the BMW i3 with Range Extender are a progressive-rate lowering set that drops the front approximately 1.2 inches and the rear approximately 0.8 inches, lowering the center of gravity to reduce body roll and sharpen handling while keeping a compliant ride. The springs are cold-formed from shot-peened 54SiCr6 spring steel, are tuned to work with the factory shocks, and are made in Germany.
