        3 Top Rated Questions

        What are the dimensions of the rotors, rotor weight (front rear), weight of calipers ?. Can off the shelf pads be used (2015 -17)? Min wheel offset (ft r)?

        • These rotors would be 14", the width would be about 0.91". They would weigh 13 lbs. The weight of the calibers would be 7 lbs and we would recommend using Wildwoodbrand brake pads as they would be the specific size you would need for the calipers rather than the standard size for the OEM system. these would require at least an 18" wheel and we would recommend having an offset of +35mm or more.

        Will these brakes clear the oem PP wheels?

        • These brakes require at least an 18" wheel for clearance and depending on the model Mustang you have the PP has 19 or 20" wheels so you will be fine using the OEM wheels.

            Wilwood Brakes rock....and stop! :-)

            2018 Base Mustang GT has ok brakes. The Wilwood takes the worry out about any fade on road or road course. The weight difference is like 100 pounds, not kidding. One thing I did notice is that the Line lock feature doesn't seem to work? I never use it so I don't care. Lets not forget about looks... These brakes are fantastic working and look great!
