Koni 50mm Lower Spring Seat

Threaded coil over spring perches allow vehicles that would normally have fixed location spring perches to gain some of the benefits of racing developed tuning techniques. Performance suspension adjustments such as ride height adjustment and corner weighting or weight jacking can be performed with threaded spring perches. KONI offers several coil over sleeves and individual components to allow both street and race cars these performance benefits. Because different vehicles have differ spring and shock mounting needs and uses, each installer will need to establish which parts are right for that particular application.
