SF Racing Track Coilovers for the 2006-2011 Audi A6 Allroad Quattro AWD (C6/4F) 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.

Perfect for Track Enthusiasts

Whether you're chasing lap times at the circuit or carving corners on backroads, SF Racing Track Coilovers deliver unmatched precision and versatility. Built with high-quality materials sourced globally, they offer premium performance at an accessible price point.
