Adjustable Spring Plate

High performance camber curve and ease of adjustment

- Corrects rear suspension camber curve to maintain optimal tire contact.
- Superior grip in turns, and straight-line braking.
- Reduced tire wear.
- Excellent for both street and track.

The core problem is illustrated by this stock 911, the tires try to follow the lean of the car in the turn  - causing poor contact as the tires roll over onto the outside edge.  Grip suffers.The stock suspension partially counters the problem by causing the tire to gain camber as the suspension compresses.

But as can be clearly seen in the picture, the rate of camber gain is far too slow and grip is poor.

ASP makes the tire gain camber faster as the suspension compresses in turns, countering the effects of body roll.   The result is a tire that remains square with the road surface, a superior contact patch, and more grip.

Porsche recognizes these same benefits and has designed aggressive camber curves into all road cars beginning with the 1990 964 and continuing through the new 997 and Cayman. With the ASP early 911s can now achieve modern suspension performance. Extremely easy to setup toe and static camber, independently. Replaces the troublesome stock eccentric adjusters with simple double-adjusters.

Unlike the stock eccentric adjuster, 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 stock 68-89 spring plate blade and spring plate cover. Bolt on - no welding required, works with torsion bars or coilovers. Use with any standard size bushing - not included - PolyBronze recommended. Requires the splined hub portion from a set of factory adjustable spring plates.
