StopTech Part Number 126.44185SR Slotted Sport Front Brake Rotor for Lexus GS and IS Models

Description

Upgrade your Lexus with the StopTech Part Number 126.44185SR Slotted Sport Front Brake Rotor, designed to enhance braking performance and durability. This high-quality, one-piece rotor is a direct replacement for factory brake discs on select Lexus models including GS and IS series from 2012 to 2019. Featuring a sleek black e-coating, the rotor is protected against corrosion, ensuring longevity and maintaining a clean appearance even after exposure to harsh conditions. The advanced metallurgy incorporates high carbon content, Molybdenum, and Chromium, which together offer quieter operation, superior crack resistance, and increased performance under demanding driving conditions.
The unique slotting pattern on these rotors helps with heat dissipation, brake dust removal, and gas evacuation, resulting in improved initial bite, especially in wet weather, and overall braking responsiveness. The slots also reduce the likelihood of pad glazing, maintaining consistent performance over time. The directional curve vane designs found on certain applications further improve cooling efficiency, reducing thermal stress and enhancing rotor longevity. Cryogenic treatment applied during manufacturing minimizes residual stress, adding to the rotor’s durability.
Designed as a direct OE replacement, these rotors are suitable for high-friction European-style brake pad compounds, providing optimal performance with upgraded braking systems. The double disk ground surface ensures a consistent friction interface for smooth and reliable braking. With features like superior resistance to thermal cracking and corrosion protection, the StopTech slotted rotors are an ideal upgrade for enthusiasts seeking both aesthetic appeal and high-performance braking capabilities for their Lexus vehicles.
