Using this Boomba Racing Brake Cooling Deflector Kit is a breeze. First, grab a jack and jack stands and get your car safely elevated in your driveway. Then, find the pre - drilled hole on the A - arm and securely mount the cooling deflectors. The all - stainless steel hardware included in the kit makes the installation straightforward and completely reversible. You don't have to drill any holes or remove your fog lights. When it comes to maintenance, the anodized finish on the deflectors provides some protection. But it's a good idea to clean them regularly with a mild soap and water solution to keep them looking good. Also, don't forget our tip: removing the rotor dust shield can really help the air flow better to your brakes and improve the overall performance of the deflectors.
