Camber-adjustable front top mounts are included, and solid rear ones where the car needs them. Adjustable camber lets you set the angle of the front wheels, and with it how the front end grips. The rebound adjuster has 12 positions, and the dampers can be rebuilt.\u003c\/p\u003e\n\u003cp\u003eAST part number: ACT-R2004S\u003c\/p\u003e\n\u003ch4\u003e5200 2-Way Motorsport (AST RIV)\u003c\/h4\u003e\u003cp\u003eRebound and compression damping each have their own adjuster, and ride height adjusts too. Compression damping sets how quickly the suspension moves in; rebound sets how quickly it extends again. 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. AST made it first of all for track driving.\u003c\/p\u003e\n\u003cp\u003eAST part number: RIV-R2004S\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.
