Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors are designed to enhance braking efficiency by improving heat dissipation through their cross-drilled surface. The vented rotor construction with straight vanes allows air to flow freely between the rotor faces, reducing the risk of overheating during aggressive braking. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. This rotor features a floating disc mounting system that accommodates thermal expansion, reducing the likelihood of warping under high-stress conditions. With a nominal thickness of 1.260 inches and a discard thickness of 1.181 inches, these rotors maintain optimal performance throughout their service life. The 11.646 inch outside diameter and 2.000 inch overall height ensure proper fitment and compatibility with the specified Lexus models.
