The front top mounts adjust for camber; the rear ones are solid. Spring rates can be changed to suit. Ride height adjusts, the rebound adjuster has 12 positions, and the dampers can be rebuilt.\u003c\/p\u003e\n\u003cp\u003eAST part number: ACC-B2206S\u003c\/p\u003e\n\u003ch4\u003e5300 3-Way Motorsport (AST RAC)\u003c\/h4\u003e\u003cp\u003eThree separate damping adjusters - rebound, low-speed compression and high-speed compression - plus adjustable ride height. Low-speed compression looks after slow, gradual movement of the suspension; high-speed compression looks after sharp, hard hits. The dampers work with external reservoirs, mounted remotely. The struts are inverted, which AST use because that design copes with heavy sideways loads and with braking. Where the car needs them, camber-adjustable front and solid rear top mounts are included. Spring rates can be changed, and the rebound adjuster has 12 positions.
