Detailed Product Description

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to provide consistent braking performance under a variety of driving conditions. Featuring a solid rotor construction, these rotors have a nominal thickness of 0.433 inches (11.000 mm) and a discard thickness of 0.354 inches (9.000 mm), ensuring durability and longevity. The cross-drilled and slotted surface enhances heat dissipation and helps remove brake dust and gases, which can improve pad bite and reduce brake fade. The floating disc mounting system allows for slight rotor movement, which helps maintain even contact with brake pads and reduces the risk of warping over time.

This rotor is specifically compatible with select Buick, Cadillac, Oldsmobile, and Pontiac models, including the Allante, Aurora, Bonneville, DeVille, Eldorado, LeSabre, Park Avenue, Riviera, Seville, and Toronado. The 5-lug hole pattern with a 4.646 inch (118.000 mm) bolt circle diameter and a center hole diameter of 2.783 inches (70.700 mm) ensures proper fitment on these vehicles.
