H&R Sport Springs are progressive rate lowering springs that drop ride height by approximately 1.2 in. at the front and 1.0 in. at the rear on the all wheel drive M4 Competition xDrive. They close the fender gap and lower the center of gravity to reduce body roll, swap in directly for the OEM springs, and retain the factory adaptive suspension. Made in Germany.
