Description Reviews H&R Threaded-Body Coil-Over Suspension Kits come directly from engineers who design and develop racing suspensions. Blueprinted as coil-overs (not just a modified shock body), the H&R units are hand-assembled in Germany by H&R Speziafedern under rigid ISO 9001 and German TUV standards. Strict attention to the function of the complete suspension system is the number one design priority. Their threaded body means that the outside of the strut or shock tubes are threaded like a bolt. This allows the threaded spring perch to be moved up or down to fine-tune the ride height, optimizing looks and handling. Equally at home on the street or the track, H&R Coil-Over Suspension Kits provide enhanced performance, improved corner-holding ability and a sleek, aggressive stance for performance driving characteristics without harshness. Professional installation recommended. Ride Height: Adjustable Threaded Sleeve Note: Avg low 0.7-1.5"F 0.6-1.5"R Lowering heights may vary on models with factory sport suspension. For models after 3/02.
