The 2009 Audi A4 Avant is one of the most popular new cars in Colorado. Rack Attack is proud to have one of the first fits for it. Both Thule and Yakima systems are available for this vehicle and both companies offer a liftime warranty on their products. We are excited about these systems for this vehicle. This photo shows a Thule Rapid Aero bar set up with permanently installed base (Thule TK14 Tracker Kit 14 ) behind the roof rail with quick release towers (Thule 430R Rapid Tracker Foot Pack ). The system is one of the easiest to put on and remove from the vehicle due to the Tracker II towers’ push-botton operated quick realease mechanism. By mounting just to the inside of the factory installed roof rails, we have made the overall appearance of the rack very sleek and integrated into the look of the vehicle. One of the managers at Prestige Audi in Lakewood, CO has this exact sytem on his very own A4 Avant.
