At 65 miles an hour (or more) a lot of pressure is exerted on these brackets as there is nothing aerodynamic about a license plate. Thats why we stamp ours from heavy gauge steel. Theyre built tough and can take a 65 mph breeze with gusts up to 100 mph. Dimensionally they are identical to original and are ready to bolt on. You are guaranteed a high-quality, and long lasting product. Rear Bracket. Polished Stainless Steel.
