The Dinan/Brembo rear brakes offer the ultimate in stopping power for the most demanding driving enthusiast. Extensive testing on the street and at the track has enabled us to develop custom systems that have been tuned for optimum performance while avoiding the foibles of typical "big brake kits," such as unbalanced proportioning, poor pedal feel and unacceptable noise levels, just to name a few. The brake calipers are available in either red or black, giving you the choice of a stealth or competition look. Dinan's custom brake pads and kits have been specially designed for use with the BMW brake wear sensors to keep the safety system fully functional something that is lost in competitors' kits. In most cases, the large rotors and calipers will require the use of aftermarket wheels for adequate brake clearance. Most of Dinan's lightweight performance wheels are recommended providing proper clearance and the ability to fit the largest tires possible for optimum performance. Be sure to check with the manufacturer or distributor of the wheels you are considering in order to verify that they offer the necessary clearance citing the Brembo "Gran Turismo" brakes as a reference.
