Factory mounts are often filled with open space and voids to allow for movement. While this sounds great in practice to providing a smoother over-all ride in factory spec, once you start applying extra power and boost all that extra space and play ends up causing you power losses and flex throughout your drive train. 034Motorsports billet mount inserts fill the existing voids in your mounts to provide a firm mounting position. This assures the power your car is making is actually being put down to the ground, reducing wheel hop and providing a more engaging experience between vehicle and driver. Unlike polyurethane insert options, these aluminum billet mounts will not wear out over time providing you with long-lasting performance for the life of your vehicle. This kit includes 3 types of drive-train mounts in one package, designed to hold in place everything from the transmission down to the rear differential. Designed for Quattro vehicles only. | Please contact us if you have questions about the 034Motorsport Billet Drive-Train Mount Inserts for 2008-2017 Audi A4/S4/RS4, A5S5RS5, & Q5/SQ5 or A8/S8 (714) 582-3330 |
