The AST 4100 single adjustable (rebound) coilover kit will transform the handling of your car. Whether you're upgrading from stock or improving on existing upgrades. An excellent set up for a dedicated track car or for a car that sees regular street use. AST 4100 struts feature a shim stack/valve and double piston design, something found only on high end race dampers or significantly more expensive but lesser performing sport dampers. You simply will not find a better performing solution, even at nearly twice the price. All AST dampers can be custom valved, inquire if interested.
This kit is not for M3 models.
