Toyota Corolla AE86 GTS- ALL $190.00 ea.
MAXGRIP by Weir Performance. A real Performance rebuild kit for the O.E.M. GTS LSD. A great alternative to expensive aftermarket LSD's for builders on a budget. This kit is not glorified O.E.M. parts. Every part has been designed to get the maximum grip possible with an O.E.M. LSD unit. Our kit features larger diameter stationary plates and clutch plates. The increase in diameter increases the surface area a total of 23% over the O.E.M. plates. Also included is our Max size springs that increase spring load a total of 60lbs. force over O.E.M. Our kit also features reversible, solid bronze, thrust washers with slotted oil passages for improved oil flow to the bearing surface. The kit also comes with a complete shim kit that allows the installer to set the clearances within the LSD to the exact specs for best performance. What does all this mean? Quicker, more responsive LSD action with maximum grip! Works great for daily and track use! This kit is easily installed.

for oil. You also get new heavy-duty springs and complete shim kit (16
assorted thicknesses) for setting the clearances within the LSD to exact
specs for best performance. Using this kit, your LSD will be more
responsive, lock faster, with maximum grip! No more one-tire
Toyota Supra 1986.5-92
We are pleased to offer three kits for the O.E.M. MkIII Supra LSD. This LSD is known for its lack of performance, this is for the most part caused by sloppy assembly at the factory. We have opened up many of these units and have not seen one yet that was worn out. Unfortunately these LSD units do not have clutch members or pressure rings to apply clamping force to the clutch plates. In order for these LSD units to function properly for performance applications they need to be correctly shimmed and the spring pressure increased. Our first kit is designed to increase the spring pressure for street and track use. It will be far more aggressive than O.E.M. but not too aggressive for daily use. Our second kit is for competition use only, higher HP cars and for the off road guys who swap in Supra LSD units into their truck rears. Finally our third kit is full lock, designed for drag racing and drifting only, not be used on the street. We will post up our rebuild procedures for this LSD soon!
