H&R Porsche Super Cup Racing Suspension - Porsche 911/964 C2, C4 Coupe 1989-1994. Porsche Super Cup Racing Suspension, is designed for the committed motorsport enthusiast who is willing to relinquish some ride comfort in return for ultimate handling performance. The firmest coil-over in the H&R street line, it is the choice for track and club sport events.

Equally at home on street or track, H&R coil-overs provide enhanced performance, improved corner-holding ability and a sleek, aggressive stance-without the bone-jarring ride of some less-advanced suspension systems. All H&R coil-overs are hand-assembled in Germany to rigid ISO 9001 and German TUV standards
