Product Line Details

The Centric Premium OE Style Cross-Drilled Disc Brake Rotors line focuses on delivering rotors that replicate original equipment specifications while incorporating performance-enhancing features such as cross-drilled surfaces and vented designs. This product line balances durability and heat management, making it suitable for Subaru WRX STI owners seeking reliable OE-style braking components with improved thermal control.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow between rotor surfaces, reducing heat buildup during braking. The cross-drilled surface pattern further aids in dissipating heat and preventing gas buildup, which can cause brake fade. The rotor's coated hat finish protects against rust and corrosion, maintaining structural integrity over time. With a 5-lug bolt pattern and a mounting bolt hole circle diameter of 114.3 mm, this rotor is engineered for direct compatibility with Subaru WRX STI models. The nominal thickness of 20.0 mm and discard thickness of 18.0 mm provide clear service limits to ensure safety and performance.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Improves heat dissipation to reduce brake fade during aggressive driving or track use
• Addresses corrosion issues common in older rotors with coated hat finish
• Restores braking performance for Subaru WRX STI vehicles with OEM specifications
• Suitable for owners seeking OE-style cross-drilled rotors for enhanced thermal management

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the bolt hole pattern and rotor dimensions match the Subaru WRX STI specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness regularly and replace when reaching discard thickness of 18.0 mm.
