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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through advanced rotor surface technology. The combination of cross-drilled holes and precision slots improves heat dissipation and helps evacuate brake dust and gases, which can degrade braking efficiency. This product line is ideal for drivers seeking reliable, consistent braking under demanding conditions, such as daily driving and light performance use.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor has an outside diameter of 319 mm (12.559 inches) and an overall height of 49.3 mm (1.941 inches). The nominal thickness is 28 mm (1.102 inches), with a discard thickness of 26 mm (1.024 inches), ensuring a long service life before replacement is necessary. The rotor includes two miscellaneous holes and a floating disc mounting system to reduce stress and improve durability. The hat finish is coated to protect against corrosion, and the rotor weighs approximately 8.18 kg (18 lbs). It is designed with five stud/lug holes, each 14.5 mm (0.571 inches) in diameter, and a mounting bolt hole circle diameter of 114.3 mm (4.5 inches). Note that this rotor does not include ABS tone rings or bearings.

Applications and Problem Solving

• Improves braking performance on Lexus Highlander, RX330, RX350, RX400h, and compatible Toyota models
• Reduces brake fade caused by heat buildup during extended braking
• Helps prevent rotor warping and cracking through vented and floating design
• Enhances brake pad bite and debris removal with slotted and cross-drilled surface
• Protects against corrosion with coated hat finish for longer rotor life

Installation Notes and Tips

• Ensure compatibility with vehicle make and model before installation
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Torque mounting bolts to manufacturer specifications to avoid rotor damage
• Check rotor thickness regularly; replace when reaching discard thickness of 26 mm
• Do not reuse old hardware or bearings as this rotor does not include them
