The Corbeau Audi S4/A4 seat brackets are manufactured to be a direct bolt in to the 2000-2002 Audi S4 and 1996-2001 V5 A4. Direct bolt in means your bracket will bolt to the existing bolt holes in your floor board with little to no modifications. Corbeau Audi seat brackets are powder coated in a black matte finish and include Double Locking Sliders.
