Ride Height Adjustment Notes: Normally, vehicle ride height is adjusted by reducing or increasing the pre-load on the coil spring. This method leads to inconsistent spring rates that are dependent upon the vehicle ride height. These coilovers allow you to adjust your vehicle's ride height independent of its spring pre-load. This method ensures that the spring rate is always consistent, no matter how high or low your car is. In addition, it ensures that the spring is always properly positioned onto the strut and effectively reduces miscellaneous and unnecessary noise.

Pillow-Ball Upper Mounts: These are included on select applications. The D2 Racing upper pillow-ball mounts have several advantages over your standard OEM mounts. First, they will tighten up your ride and give you quicker steering response. Second, some also have a built-in camber adjustment plate so you don't have to buy a separate camber kit.

Spring Rates: Custom spring rates are now available on select kits! Please email us for pricing and availability (this will generally add $100 to the total price).
