The AE86 has a cult following mainly NOT for it’s straight line abilities, but of it’s rally and drifting cult following abilities. So now with the new 86, BRZ and FRS, it’s time to keep the tradition going. The stock LSD that comes with the car, factory, isn’t designed to cope with performance use and abuse. It’s just a basic addition. When you want something that will last, there’s no better option than the Tomei Technical Trax 2 Way LSD. It’s being used already in a D1GP pro drift machine in Japan too!   The perfect cam angle has been designed to produce the best response during constant throttle work. The locking mechanism characteristics, is purposely designed to suit drifting, at any race track, anywhere in the world.  
Tomei LSDs are 2 way systems. This design dynamically engages during acceleration & deceleration. With this 2 way LSD, any RWD configured sports car can be effortlessly controlled with accurate co-ordination.
With most vehicles, it’s necessary to change out the side flanges when upgrading to a high performance LSD unit. The T-Trax Advance unit is a universal fit, meaning that it can be used with those vehicles stock side flanges. This does not affect the performance of this LSD at all. Yet it does help to reduce costs for the end user. The Advance Disk technology was incorporated into the unit, for quieter and more efficient operation. By changing the design of the surface, the transition characteristics into the engagement of the LSD internals has proven to be smoother. The change in behavior during throttle on and off is minimal, thus maintaining stable mechanical operation of the entire system. In addition, the typical operational sounds emitted from a bulky limited slip differential are kept at a discrete level, so the unit can be used even for daily driving. Larger Friction Disk Surface Area, Transfers Power Effectively Due to the incorporation of the larger friction disks, torque is evenly distributed instantaneously, to both the left & right wheels. Even during hard drag race launches. The high locking mechanism also ensures greater vehicle control during drifting & provides the highest performance for the money.   THE HIGHEST INITIAL TORQUE LSD Spring disks are used to engage the clutches in the Technical Trax Advance LSDs. The structure that produces this high initial torque was kept compact. The longevity of the unit was proved by the variable spring rate tested during extreme driving conditions over an extended period.   APPLICATION: Toyota 86 / Subaru BRZ / Scion FRS TYPE: TGA PART NUMBER: 562047 INCLUDED: 2L SPECIAL DIFFERENTIAL OIL     TECHNICAL TRAX LSD
