Cusco LSD-1C8-C15 Type-RS Limited Slip Differential Rear Way - 1 1.5

The Cusco LSD-1C8-C15 Type-RS Limited Slip Differential is a high-performance rear differential designed specifically for the 2023+ Toyota GR Corolla. This advanced LSD system maximizes traction and control by preventing wheelspin and ensuring both rear wheels maintain optimal grip during acceleration and cornering.

Type-RS Technology:

The Type-RS design features an innovative coil spring system that provides low initial torque (2-4 kg.m) for responsive handling and extended durability. Unlike conventional LSD systems, the RS coil springs maintain consistent pressure across the clutch plates, resulting in smoother engagement, reduced chattering noise, and prolonged component life. The spring-activated design minimizes drivetrain power loss while delivering a more direct driving feel with improved throttle control.

1 & 1.5 Way Configuration:

This differential features a switchable 1 & 1.5 Way design. The 1-Way setting locks only during acceleration, making it ideal for maximizing traction while allowing easy maneuvering when off-throttle. The 1.5-Way setting provides locking during both acceleration and deceleration, with stronger locking force during acceleration. This configuration offers better engine braking than a 1-Way setup while reducing understeer compared to a 2-Way system, making it a popular choice among performance enthusiasts and racers.

Key Features:

• Low initial torque setting for smooth, responsive handling
• RS coil spring technology for consistent pressure and reduced chatter
• Switchable between 1-Way and 1.5-Way configurations
• Three-step activation process for direct, predictable engagement
• Extended clutch plate life due to reduced operating pressures
• Minimized drivetrain power loss compared to traditional LSDs
• Direct-fit replacement for 2023+ GR Corolla rear differential

Application:

This unit is specifically designed for the rear axle of the 2023+ Toyota GR Corolla (GZEA14 G16E-GTS). Professional installation is recommended, including proper shimming, backlash adjustment, and gear pattern verification. Use with recommended 75W-85 GL-5 differential fluid with friction modifiers for optimal performance.
