Specifications Front Drop 1.7 " Rear Drop 1.9" Description D2 PRO Series lowering springs optimize and improve handling characteristics by offering a reduction in ride height while maintaining exceptional ride quality through the use of a progressive rate spring. All of our springs come with a Lifetime Warranty and are manufactured of 55 chrome silicon steel in an ISO 9001 and TUV approved facility. D2 Racing PRO Series lowering springs have been designed to give your car superior handling with an aggressive race look. Most other brands use a linear rate, but D2 utilizes a progressive rate for several reasons. A progressive rate allows a plush comfortable ride under normal travel, but since the rate shifts higher during compression, it stops "body roll" during heavy braking, hard acceleration, or fast cornering. By lowering the center of gravity from OE height you dramatically improve performance and handling characteristics.   Features: Progressive Spring Rates: Allows for a comfortable ride under normal travel and during compression, the rate increase to help with body roll High Tensile Wires: Cold wound for strength and shot peened for increased stress relieft 1 Year Manufacturer Warranty.
