EBC Brake Upgrade Parts. EBC Greenstuff brake pads offer exceptional performance without the drawbacks of a full-race brake pad. Braking force comes on strong from first pedal application, delivering powerful braking right up to a blistering 500-C disc temperature. Greenstuff pads contain no carbon black, which deposits on wheels, or metallic fibers, which can cause fast rotor wear and noise. EBC Turbo Groove Rotors are precision CNC-machined using quality grey iron castings. Sold in pairs, Turbo Groove Rotors feature a combination groove and blind hole design. The blind holes resist cracking and help surface degassing under heavy brake load. The grooves promote flat pad and disc wear and help clean debris and dust from the braking surface. Rotors are zinc plated and gold passivated to prevent corrosion in areas not swept by the pad. The combination of Greenstuff pads and Turbo Groove rotors will yield large gains in braking performance at a reasonable cost.
