SF Racing Track Coilovers for 2009-2015 Infiniti FX50 (S51)

Product Details

SF Racing Track Coilovers for the 2009-2015 Infiniti FX50 (S51) 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.

SF Racing Sport Coilovers for the 2009-2015 Infiniti FX50 (S51) are engineered for enthusiasts who demand precision and control on the track. These coilovers are specifically designed with advanced valving in the struts, delivering superior handling and responsiveness tailored for track racing while still being versatile enough for street use.

SF Track Coilovers provide a wide range of ride height adjustability below factory height without compromising spring travel, ensuring an optimal balance between performance and comfort. Each corner features 32 levels of damping adjustability, allowing precise tuning of rebound and compression with a single adjustment knob. Our coilovers include hardened rubber top mounts to minimize noise and enhance durability, and some have optional pillowball bushings available to increase steering response even more.

Protected with an anodized coating, SF Track Coilovers are built to resist rust and corrosion under extreme track conditions and harsh environmental exposure. The result is a coilover system that’s durable, reliable, and crafted for motorsport-level performance.
