Show original supplier description
The Tomei ZA2 2-Way LSD Kit Technical Trax Advance offers significant advantages over similar products with its advanced design and components. It incorporates optimized cam angles, spring discs, and larger surface area clutch discs, coupled with a higher initial torque setting. These enhancements deliver improved corner entry stability, more precise driving control, superior corner exit traction, and quicker response when navigating consecutive turns. The new surface finish on the friction material ensures smoother engagement and more stable performance whether on or off the throttle, eliminating the loud LSD crackling sounds often associated with daily street-driven vehicles. Tomei's robust case design prevents performance reduction due to such stresses. Each T-TRAX ADVANCE kit comes complete with all necessary components for installation, including Tomei special differential oil, carrier cover gaskets, bearings, and oil seals, ensuring a comprehensive upgrade for the differential. This LSD is specifically designed for the 1990-1993 Mazda Miata 1.6L, and also fits 1990-1997 Mazda Miata RWD models.
