The H&R 09-15 BMW 740i F01 Sport Spring (w/o Self-Leveling) is a performance spring designed to lower the ride height of your BMW 740i by 1.5 inches in the front and 1.3 inches in the rear. The spring is made from a high quality steel and is designed to provide improved handling and cornering performance. This spring will not affect the self-leveling suspension of your vehicle, so it can be used with or without the self-leveling feature. The spring is designed to provide improved handling, better cornering, and improved ride quality.
