Excellent products, just adds the carbon look to the steering column and the rest of the carbon in the car. Nice touch.
Excellent finish & quality to the product and great fit to the rear end of the car. Would happily recomend to fellow RS6 C8 owners.
Installed, the screens were a little hard to get done, but once on it changes the entire front end, I had also added the R style twins ducts. VERY nice.
