StopTech 121.33118 Plain Sport Disc Brake Rotor

The StopTech 121.33118 is a plain-face sport brake rotor engineered as a direct OEM replacement that delivers improved braking performance over standard factory rotors. Manufactured to StopTech's rigorous quality standards, this rotor is designed to drop directly into factory brake systems while working with the stock calipers already on your vehicle.

StopTech's Sport Rotors are produced from high-quality iron castings with advanced high-carbon metallurgy that reduces brake noise, improves crack resistance, and provides more consistent performance compared to entry-level replacement rotors. A protective black e-coating is applied to non-braking surfaces to guard against rust and corrosion, keeping the rotor looking clean behind open-spoke wheels.

Key Features:

• Plain smooth face — optimized for street driving and compatibility with a wide range of brake pad compounds
• High-carbon metallurgy — reduces pad squeal and improves thermal crack resistance
• Black e-coating — corrosion-resistant finish on non-friction surfaces
• Direct OEM replacement — bolt-on fitment using factory calipers; no modifications required
• 1-piece construction — lightweight, durable, and road-ready right out of the box
• Manufactured to meet or exceed OEM specifications — consistent, reliable stopping power

The StopTech 121.33118 is an excellent upgrade for drivers seeking improved brake feel and longevity over stock rotors without the added cost of a big brake kit. Cross-reference part numbers in the same rotor family include 120.33118, 125.33118, 126.33118, 127.33118, and 128.33118.
