Description

The Tomei ZA2 2-Way LSD Kit, also known as the Technical Trax Advance, is engineered to enhance the driving dynamics of your vehicle. This limited-slip differential (LSD) kit features optimized cam angles, spring discs, and larger surface area clutch discs, all contributing to a higher initial torque setting. These advancements translate into improved corner entry, more precise driving control, and superior corner exit traction, allowing for quicker responses through successive corners. The T-TRAX ADVANCE system prioritizes a quieter and more efficient transmission operation. Its unique ADVANCE DISC design offers improved friction quality with a new surface finish, ensuring smoother operations and more stable performance whether you are on or off the throttle. Unlike some aftermarket LSDs, this Tomei unit minimizes loud LSD crackling sounds, making it a more comfortable option for daily street use. The T-TRAX ADVANCE kit includes everything required for installation, such as Tomei special diff oil, carrier cover gaskets, bearings, and oil seals, which are essential for upgrading the differential on the majority of vehicle line-ups. This specific kit is designed for the 1990-1997 Mazda Miata, including NA6CE models with the 1.6L B6 engine. Fitment Industries has confirmed that this LSD fits 1990-1997 Mazda Miata RWD models and JD Customs USA lists fitment for 1990-1997 and 1999-2005 Mazda Miata models. The product is also listed as a fitment for the 1994 Mazda Miata M Edition RWD.
