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

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat management and reduced brake fade. The cross-drilled surface pattern allows for better ventilation and water dispersion, which is particularly beneficial for BMW vehicles used in spirited driving or moderate track conditions. The coated hat finish helps resist corrosion, extending rotor life while maintaining consistent braking performance.

Technical Description and Compatibility

This disc brake rotor is a solid type, optimized for BMW models such as the 524td, 528e, 533i, 535i, 535is, 635CSi, M5, and M6. The rotor’s 11.181-inch diameter and 0.394-inch nominal thickness ensure compatibility with the specified vehicles’ braking systems. The 5-lug hole pattern with a 4.724-inch bolt circle diameter matches factory specifications, allowing for straightforward installation. The rotor does not include bearings or an ABS tone ring, so it is intended for vehicles that do not require these components integrated into the rotor.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on compatible BMW models
• Improved heat dissipation to reduce brake fade during aggressive driving
• Enhanced braking response in wet conditions due to cross-drilled design
• Corrosion resistance from coated hat finish to extend rotor lifespan
• Maintains factory fitment and performance standards for BMW 5 and 6 Series vehicles

Installation Notes and Tips

• Ensure rotor thickness is within discard limits before installation (minimum 0.331 inches)
• Verify compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
• Clean rotor surface before installation to remove any protective coatings or residues
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and replace if worn to ensure optimal rotor performance

Quality Assurance and Warranty

StopTech Sport Cross-Drilled Disc Brake Rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rotors undergo rigorous quality control to ensure durability and consistent braking performance. Warranty coverage details should be confirmed with the original product documentation or authorized distributor.
