Featuring a vented rotor construction with straight vanes, these rotors improve airflow to reduce heat buildup during aggressive driving or towing. The cross-drilled surface pattern helps to evacuate gases and debris from the braking surface, maintaining consistent pad contact and reducing brake fade. The coated hat finish protects the rotor center from rust and corrosion, ensuring durability over time. This rotor uses a floating disc mounting system, which allows slight movement between the rotor and hub to reduce stress and improve braking smoothness. With a 5-lug, 112 mm bolt circle diameter and a center hole diameter of 2.638 inches (67.000 mm), it fits securely on compatible Mercedes-Benz models.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Cross-Drilled Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors that balance heat management and durability. This product line is engineered to provide enhanced braking performance for street and light track use, making it suitable for Mercedes-Benz vehicles that demand reliable stopping power under varied driving conditions. The cross-drilled design is a key feature of this line, aimed at improving rotor cooling and brake pad bite without compromising rotor strength.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReduces brake fade during extended or aggressive braking\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to prevent rotor warping\u003c\/li\u003e\n\u003cli\u003eMinimizes corrosion on rotor hats with coated finish\u003c\/li\u003e\n\u003cli\u003eEnhances braking consistency for Mercedes-Benz G55 AMG and GL series models\u003c\/li\u003e\n\u003cli\u003eAddresses uneven pad wear caused by overheating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (1.157 inches) before installation\u003c\/li\u003e\n\u003cli\u003eVerify compatibility with vehicle’s 5-lug, 112 mm bolt pattern\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for mounting bolts to avoid rotor distortion\u003c\/li\u003e\n\u003cli\u003eInspect brake pads and calipers during installation for optimal performance\u003c\/li\u003e\n\u003cli\u003eBreak in new rotors according to manufacturer recommendations to ensure proper bedding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eStopTech Sport Cross-Drilled Disc Brake Rotors are manufactured to meet or exceed OEM specifications for fit, form, and function.
