Functional is the key word. Simply putting scoops on the rear quarter scallop does not make a functional brake scoop. It takes cutting the quarter panel, the wheel house and fashioning a tube in between. This is fairly simple for racing where the interior is not refitted but more complex when you want to keep the interior. The scoop and tube have to be weatherproof, such that rainwater not a problem and it's best if you figure a way out that separates air/water. Even if you get the cutout and tubing fashioned, there's no assurance of airflow will be directed at the brakes. Cutting up your quarter panels often degrades the value of your car. It costs about $1,000 to restore sides to cars that have been made into Shelby clones with functional side scoops. Be absolutely sure you want to do it.
