Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed specifically for the Pontiac GTO, providing a precise fit and reliable braking performance. The vented rotor design incorporates pillar-style vanes that improve airflow and heat dissipation, reducing the risk of brake fade during aggressive driving or heavy braking conditions. The cross-drilled and slotted surface pattern helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent pad contact and improving braking response.

The rotor features a coated hat finish that protects against rust and corrosion, extending the service life of the rotor. The floating disc mounting system allows for slight movement between the rotor and hub, which helps to reduce stress and warping under thermal expansion. With a nominal thickness of 1.260 inches and a discard thickness of 1.181 inches, these rotors meet strict specifications for safe and effective braking.
