EBC MD3089XC XC Series Contour Brake Rotor Stainless Steel Floating Disc

The EBC MD3089XC XC Series Contour Brake Rotor delivers superior braking performance through advanced engineering and premium materials. Built with a proprietary stainless steel blend, this rotor provides up to 10% improved friction effect compared to standard heat-treated stainless steel rotors, resulting in stronger, more consistent braking power.

Key Features:

• High-friction stainless steel construction for enhanced braking performance
• Lightweight aluminum center hub with 6-button drive system reduces weight by 5-10%
• Patented SD-System square-sided buttons allow unrestricted thermal expansion
• Maintains perfectly flat, true rotor surface throughout entire service life
• Line contact drive force transmission for superior durability over circular buttons
• Contoured wave design for optimized heat dissipation and reduced weight
• Floating rotor design prevents distortion under extreme heat and stress

The innovative SD-System square button design is engineered to extend rotor life 5-10 times longer than conventional circular button rotors by allowing bidirectional thermal expansion without constraint. This prevents warping and maintains optimal rotor flatness, meaning replacement is typically only needed due to impact damage or wear limits after extended mileage. The lightweight alloy center hub with 6-button mounting system further reduces unsprung weight while maintaining structural integrity under heavy braking loads.
