• Nominal thickness of 1.260 inches (32.000 mm) and discard thickness of 1.181 inches (30.000 mm)
• Outside diameter of 13.780 inches (350.000 mm) for precise fitment
• Overall height of 1.720 inches (43.700 mm)

Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors are part of StopTech's Sport line, designed to provide enhanced braking performance for street and light track use. The cross-drilled surface pattern improves ventilation and helps dissipate heat and brake gases, reducing the risk of brake fade during aggressive driving. The vented rotor design features pillar-style vanes that promote airflow between the rotor faces, maintaining optimal operating temperatures. The coated hat finish protects against corrosion, extending rotor life and maintaining appearance. This rotor uses a floating disc mounting system to accommodate thermal expansion and reduce stress on the rotor, improving durability.

Specifically engineered for Mitsubishi Lancer models, the rotor features a 5-lug hole pattern with a 4.500 inch (114.300 mm) bolt circle diameter and 0.492 inch (12.500 mm) stud hole diameter. The center hole diameter measures 2.717 inches (69.000 mm), ensuring proper hub fitment. Weighing approximately 25.3 lbs (11.5 kgs), this rotor balances strength and weight for effective braking without excessive unsprung mass.

Applications and Problem Solving

• Reduces brake fade during spirited driving or track use
• Improves heat dissipation compared to standard rotors
• Minimizes corrosion on the rotor hat area
• Provides consistent braking performance for Mitsubishi Lancer vehicles
• Addresses rotor warping issues through vented and floating design

Installation Notes and Tips

• Ensure compatibility with Mitsubishi Lancer models using 5-lug wheels and specified bolt pattern
• Check rotor thickness before installation; discard thickness is 1.181 inches (30.000 mm)
• Use proper torque specifications on mounting bolts to avoid rotor distortion
• Inspect brake pads and calipers for wear during rotor replacement
• Perform a bed-in procedure after installation for optimal braking performance
