Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is specifically designed for select Mercedes-Benz SL-Class vehicles, including the 600SL, SL500, and SL600. The rotor measures 11.811 inches (300 mm) in outside diameter and features a vented design with straight vanes to promote efficient heat dissipation during braking. The slotted and drilled surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing the risk of brake fade. The coated hat finish provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 0.906 inches (23.000 mm) and a discard thickness of 0.764 inches (19.400 mm), this rotor meets strict specifications for durability and performance.
