• Overall diameter of 12.795 inches (325 mm) and nominal thickness of 1.142 inches (29 mm)

Product Line Details: StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering enhanced braking performance through advanced rotor surface technology. The combination of cross-drilled holes and precision slots helps to evacuate heat, brake dust, and gases more efficiently than standard rotors. This design reduces the risk of brake fade and maintains consistent pedal feel, making it suitable for daily driving and moderate performance applications on vehicles like the Buick Enclave and Chevrolet Traverse.

Technical Specifications and Features

This vented rotor features a solid construction with an overall height of 2.157 inches (54.8 mm) and a center hole diameter of 2.972 inches (75.5 mm). The rotor weighs approximately 23.15 lbs (10.52 kg), balancing durability and weight considerations. It does not include ABS tone rings or bearings, so these components must be sourced separately if required. The rotor’s floating disc mounting system helps reduce stress and warping under heavy braking conditions.

Applications and Problem Solving

• Compatible with Buick Acadia, Acadia Limited, Chevrolet Enclave, GMC Outlook, and Saturn Traverse models
• Addresses brake fade caused by excessive heat buildup during prolonged braking
• Reduces brake dust accumulation for cleaner rotor surfaces and pads
• Minimizes rotor warping and vibration through vented and floating design
• Improves wet-weather braking performance by channeling water away from the rotor surface

Installation Notes and Tips

• Ensure compatibility with vehicle’s 6-lug wheel hub and 5.197-inch bolt circle diameter
• Check rotor thickness before installation; discard thickness is 1.083 inches (27.5 mm)
• Verify that ABS tone rings and bearings are installed separately if your vehicle requires them
• Use proper torque specifications on mounting bolts to maintain rotor alignment and performance
• Inspect brake pads and calipers during installation for optimal braking system function
