SF Racing Track Coilovers for the 2003-2008 BMW Z4 are the best coilovers available for track-driven cars. SF Track Coilovers were designed to give a wide range of ride height adjustability without reducing the spring travel. The Track version is geared for performance on the track with a 20W damper oil and unique valving in comparison to the Sport Coilovers.
Each corner of the car has 32 levels (or clicks) of damping adjustability. This combines both the rebound and compression into one adjustment knob. The coilovers also use rubber top mounts to help reduce the noise that typically comes with high performance aftermarket coilovers. SF Coilovers come standard with an anodized coating to protect against rust and corrosion caused by extreme use and harsh external elements.
SF Racing parts are manufactured from high quality products sourced from around the world while still maintaining a very affordable price. SF Racing Track Coilovers are the perfect setup for your daily driver.
