Hi Spec Replacement Rotor Discs

In this section you will find the HiSpec Motorsport replacement rotors, brake discs that are available for the entire range of Hi Spec brake kits from the Billet 4 conversions through to the Mega Monster conversions that we retail. We understand that having readily available replacement parts is extremely important when it comes to your performance brakes. Getting ready for a track day or MOT? Or just have your discs just come to the end of their life? We have what you need.
The following types of rotors are available for each of the discs sizes shown
Plain Rotors: The most economical disc finish option. Plain rotors are more resistant to cracking and warping.
Grooved Rotors: Improves heat dissipation and reduces gas build up on disc and pad surfaces allowing cleaner contact areas. Help with continuous pad deglazing. In wet weather grooves prevent a film of water building up between the disc and the pads.
Spot Grooved Rotors: Improves heat dissipation and reduces gas build up on disc and pad surfaces allowing cleaner contact areas. Help with continuous pad deglazing. In wet weather grooves prevent a film of water building up between the disc and the pads.
Race Grooved Rotors: The race stops before the end of the disc to ensure that the edge of the disc is stronger and less likely to crack. The grooved improve heat dissipation and reduces gas build up on disc, in wet weather grooves prevent a film of water building up between the disc and the pads. Recommended for heavy braking and track use.
Cross Drilled Rotors: Improves heat dissipation and reduces gas build up on disc and pad surfaces allowing cleaner contact areas. Under strenuous circumstances are more likely to crack than grooved or plain rotors. Only available on vented and solid rotors.
Combi Rotors: A more visual effect for show cars, the combi finish combines the benefits and the weaknesses of both the grooved and cross drilled discs. Only available on vented and solid rotors.
With such a huge range of rotors available in a range of styles and designs we believe that we can cater for almost every requirement.
