StopTech 227.44157R Select Sport Drilled & Slotted Disc Brake Rotor Rear Right

The StopTech 227.44157R Select Sport Drilled & Slotted Brake Rotor is a high-performance, direct-fit rear right replacement rotor engineered to deliver a meaningful upgrade over standard OEM brake rotors. Combining a drilled and slotted surface pattern, this rotor is designed to improve braking bite, reduce heat buildup, and disperse brake dust and gases more effectively than a smooth rotor.

Key Features:

• Drilled & Slotted Design: Cross-drilling and slotting work together to improve bite, prevent pad glazing, and enhance both wet and dry braking performance
• Zinc Coating: Full zinc coating on non-friction surfaces provides strong corrosion resistance, extending the service life of the rotor
• G11 Metallurgy: Premium iron alloy formula delivers quieter operation, improved crack resistance, and consistent thermal performance
• Machined Non-Friction Surfaces: Precision-machined hat and non-friction areas ensure proper fitment and reduce runout
• Non-Directional Finish: Ready to install straight out of the box without additional break-in machining
• OE-Style Direct Fit: Bolt-on replacement compatible with factory brake calipers and hardware — no modification required
• Position: Rear Right (Passenger Side)

StopTech's Select Sport line bridges the gap between everyday street driving and spirited performance use, offering a significant visual and functional upgrade at an accessible price point. The drilled holes and slots give the rotor an aggressive appearance behind open-spoke wheels while delivering measurable improvements in braking response and fade resistance. Built by StopTech — a brand with ISO/TS 16949:2009 certification and decades of motorsport engineering heritage — the 227.44157R is a confident choice for drivers seeking better braking without a full big brake kit upgrade.
