Show original supplier description
The Tomei Technical Trax Advance 1.5-Way LSD (TC101B-TYTD1) is a high-performance limited-slip differential engineered to enhance driving dynamics for specific Toyota models. This unit offers significant advantages over standard differentials, including optimized cam angles, spring discs, a larger surface area clutch disc, and an increased initial torque setting. These features collectively result in improved corner entry stability, more precise driver control, enhanced traction during corner exit, and quicker response through successive turns, offering a superior performance experience. Key specifications for this LSD include a Ring Gear Bolt PCD of 125mm, an 85mm disk diameter, 6 interior and 6 exterior disk teeth, and a 1.6mm disk thickness. It utilizes an M11 (8) size for ring gear bolts and has 23 spline teeth with an inner flange diameter of 30.0mm. The initial torque is set between 5.5-6.0 kg/m, and the pressure ring cam angle is 50° x 20°. A notable benefit is its utilization of original factory flanges, contributing to quieter operation and improved efficiency compared to other aftermarket options. This Tomei Technical Trax Advance LSD Pro Kit is specifically designed for the 1986-1992 Toyota Corolla Sport GT-S AE86 models equipped with the 4A-G 16V engine. The kit includes one LSD Pro Kit.
