Zimmermann drilled rotors offer the ultimate in cooling for ultra high performance street and race applications. The hole pattern is calculated to provide maximum cooling without impairing strength or swept area. Also, the holes are radiused to the wear limit to reduce pad wear and to provide visual wear inspection. These rotors are specifically designed and built as high performance drilled rotors. Beware of rotors that are "aftermarket-drilled", many are not properly heat treated after drilling.

Please note: Price is for the front pair only.
