RSS Club Sport Coil Overs have more of everything –– more spring rate, more shock valving –– and are designed for the committed motorsport enthusiast who requires the ultimate in handling performance. The result is flat cornering and supreme directional control –– a perfect choice for the true street tuner that lives to abuse the track. Like the H&R Street Performance Coil Overs, RSS Club Sport Coil Overs feature an H&R exclusive dynamic damper technology and a fully threaded shock body (not an imitation sleeve-over).
