StopTech Sport Slotted Rotor - Rear Left

StopTech Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique slotting aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance.

Additional Information

Premium rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction; European style brake pad compounds. Slotted for increased bite; improved looks and better performance

Application Summary

2015 - 2020 Acura TLX, 2017 - 2019 Honda CR-V

Part Type

Disc Brake Rotor

Product Overview

Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where StopTech SportStop slotted brake rotors make a big difference. StopTech SportStop Slotted Brake Rotors are a true performance rotor and feature:
• Power Alloy castings (on select applications)
• Engineered Performance Rotor
• Superior resistance to cracking due to thermal stress
• Increased molybdenum (higher carbon)content that extends reliability, service life and helps reduce NVH “noise” issues
• Rotor material is a direct descendant of the patented AeroRotor from StopTech
• Introducing directional curve vane design (on select applications)
• Improved vane design or OE equivalent on all rotors
• Center split castings
• New short slot design runs perpendicular to the vane to preserve rotor strength.
• Direct OE Replacement
• Improved wet weather response
• Increased initial “bite”
• Double disc ground for a consistent friction surface and Improved pad bed-in
• Mill balanced
• Black E-Coated non-friction surfaces on “Power Alloy” rotors
• Enhances open wheel appearance

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Reference Information

Brake Rotors Sport Slotted Rotor, Left

StopTech slotted brake rotors offer efficient, smooth and longer lasting stopping power. These one-piece performance upgrades are cast from a unique power alloy--chromium and iron--and mill-balanced. They are then CNC-machined and most are given a durable black E-coating applied to the non-friction areas of the rotors to prevent unsightly corrosion for a lasting, sporty appeal. Add bite and improved wet and dry braking performance; step up to StopTech slotted brake rotors and give your braking a boost.
