You don't have to be a racer to benefit from drilled rotors. After all, Porsche puts them on their street cars. Made in Germany, Zimmermann rotors set a standard above all but the most expensive racing rotors. Drilled are proven superior to grooves in allowing hot brake pad gases to escape for improved air-flow and keep your brakes cooler.
