StopTech 127.34147L Sport Drilled & Slotted Brake Rotor Rear Left

The StopTech 127.34147L Sport Drilled & Slotted Brake Rotor is a premium one-piece, direct-replacement rear left brake disc engineered to bolt directly onto factory brake systems and work seamlessly with stock calipers. Combining aggressive aesthetics with measurable performance gains, this rotor is an ideal upgrade for drivers seeking more from their factory braking setup.

Key Features:

• Cross-Drilled & Slotted Surface: The combination of cross-drilling and slotting promotes heat dissipation, expels brake dust and gases, and helps prevent brake pad glazing for consistent, reliable stopping power in both wet and dry conditions
• Enhanced Bite & Braking Performance: The rotor's surface geometry increases pad-to-rotor contact effectiveness, delivering improved pedal feel and reduced stopping distances over a standard OE rotor
• Black E-Coat Finish: A durable black electrophoretic coating is applied to the non-swept areas of the rotor, providing excellent corrosion resistance and a clean, finished appearance behind the wheel
• High-Carbon Metallurgy: Manufactured using a high-carbon iron formulation (in most applications) that reduces brake noise, improves crack resistance, and enhances overall thermal performance versus standard grey iron rotors
• Direct OE Replacement: Designed as a true one-piece drop-in replacement — no modifications required — compatible with factory calipers and hardware
• Rear Left Fitment: This is the rear left (driver's side) rotor; sold individually

StopTech Sport Drilled & Slotted rotors are manufactured to meet or exceed all original equipment specifications, making them a straightforward upgrade for performance-oriented street driving. The combination of functional cross-drilling and slotting also delivers a visually striking look through open-spoke wheels.
