1994-1997 Audi S6 Sedan (C4)
1994-1997 Audi S6 Avant (C4)
The first generation Audi S6 was the beginning of a new era of performance sedans and wagons from Audi. Originally produced from 1994-1997, the C4 S6 was offered in two body styles, including both sedan and wagon (Avant) variants. Performance-wise, the C4 S6 could be optioned with either a 2.2 liter turbo inline-5 cylinder or a 4.2 liter naturally aspirated V8, both offering brisk 0-60 times for the era. While a traditional torque converter automatic was an option for both engines, most enthusiasts opted for either the 5 or 6-speed manual, which made the C4 S6 far more engaging to drive spiritedly both on the street and at the track.

Performance Street and Track Wheel Fitment
Wider fitments for enhanced performance
These fitments are the perfect match for weekend track warriors and hardcore racers seeking to maximize the wheel and tire size that they can fit on their C4 S6. These aggressive wheel specs will typically require supportive modifications commonly found on track cars. Available in 17" & 18" diameters to cater to a variety of performance-focused tire sizes and compounds. With a focus on brake clearance, our Audi-specific fitments are able to clear the standard S6 brakes with ease, as well as a variety of aftermarket BBKs. However, brake clearance can vary depending on wheel design, as the TC-10RT will have better clearance for larger aftermarket brakes compared to the other designs (VS-5RS/ML-10RT) offered in the same fitments.

Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hard core racer competing for a spot on the podium, negative camber is a vital part of chassis setup that has many benefits.
