ASP can be fit to '69-'89 911 series cars.
Both aluminum and steel trailing arms can be used.
ASP can be used with torsion bars or coil-over conversions.
The ASP is packaged to be ordered 1 kit for 1 car.
Spring plate bushings are not included with the ASP. PolybronzeÔ spring plate bearings are highly recommended. Any bushing designed for use with factory spring plates may be used.
ASP works in combination with the splined hub portion of the factory adjustable spring plates as equipped on ’77-’89 models. Alternatively '69-'86 models can use the QuickChange Spring Plate splined hub to gain all the benefits of QuickChange.
Following installation of the ASP, a corner balance and alignment must be performed.
