ASP Adjustable Spring Plate Kit, bushings not included, 911/911 Turbo (1969-89) $1200.00 ERMP-2142100
The ASP Adjustable Spring Plate kit corrects the rear suspension camber curve to maintain an optimal tire contact patch. What this yields is superior grip in turns, superior grip in straight-line braking, reduced tire wear - excellent benefits for both street and track. Porsche recognized these same benefits when they designed aggressive camber curves into all road cars beginning with the 1990 964 and continuing through the new 911 models. With the ASP early 911s can now achieve modern suspension performance.
Improved contact patch for both outside and inside tires on turns
Improved contact patch for straight-line braking
Go street-to-track without running "compromise" camber setting
Run less static camber for superior tire wear, reduced camber thrust/lower rolling resistance on straights
Setup is fast, easy, and accurate. Toe and static camber can be dialed in independently. The troublesome stock eccentric adjusters are replaced with simple double-adjusters. Unlike the stock eccentric adjusters, ASP allows adjustment with vehicle weight resting on the tires making it easy to read a camber / toe gauge while turning the adjuster. By making equal adjuster turns on both driver and passenger sides, quick changes can be made trackside even if a camber gauge is not available.
Upper and lower double-adjusters
Rotate same direction to set toe
Rotate opposite direction to set static camber
Replaces factory spring plate blade and spring plate cover (1968-89). Bolt on - no welding required; works with torsion bars or coilovers. Works with any standard size spring plate bushing - including PolyBronze (sold separately).
