Designed with vented, slotted surfaces and a coated hat finish, these rotors provide consistent heat dissipation and improved pad bite for vehicles like the Chevrolet S10 and GMC Sonoma.

• Vented disc brake rotor with straight vane design for enhanced cooling
• Slotted surface type to reduce brake fade and improve pad cleaning
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better thermal expansion management
• Compatible with 5-lug wheel patterns and 4.748" bolt circle diameter
• Nominal thickness of 1.035 inches (26.3 mm) with discard thickness at 0.957 inches (24.3 mm)
• Overall diameter of 10.5 inches (266.7 mm) and overall height of 2.047 inches (52 mm)

Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are designed specifically for use on a range of Buick, Cadillac, Chevrolet, GMC, and Oldsmobile models including the Blazer, Bravada, Eldorado, Jimmy, Riviera, S10, S10 Blazer, S15, S15 Jimmy, Seville, Sonoma, and Toronado. These rotors feature a vented design with straight vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade under demanding conditions.

The slotted surface enhances pad bite and helps channel away dust and gases generated during braking, maintaining consistent stopping power. The coated hat finish protects the rotor’s central hub from corrosion, which is especially beneficial in environments prone to moisture and road salt exposure. The floating disc mounting allows for slight movement between the rotor and hub, accommodating thermal expansion and reducing stress on the braking system.
