The Corbeau Audi Quattro/5000 seat brackets are manufactured to be a direct bolt in to the 1984-1994 Audi Quattro and 5000 (Std. Only). 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.
