Front LSD Mitsubishi EVO V-IX

The front LSD differential is a necessary part of Mitsubishi EVO cars. These unique EVO diffs are praised by customers for their strength as they don´t bend or crack as some other differentials on market! 

The differentials have a large number of plates - high durability and good locking characteristics. The most common preload we dealt with was about 40 Nm on the front diff, however, the differential can be set to a different preload based on racing specifications (preload around 30-80Nm).

There are time – tested and good functional angles, homologated by FIA, inspired by Ralliart. The two pairs of ramp angles are on the same carrier, so you can swap to a different pair of angles when you disassemble the differential!

Every part is hardened with the newest technology hardening treatment. Advantage is that in the case of damage, it is possible to buy also part by part, not only complete differential.

It is clear that limited slip differential is much more usable in racing cars than standard open differential, which is good tool to increase driveability, but cannot distribute the maximum power in performance conditions or on surfaces with different adhesion on right and left wheel.

Plate LSD contains mechanism with ramps on pressure rings and cross shaft and steel plates that work as a clutch. As the car accelerates, the cross shaft is pushed to the the ramps of the pressure rings. which are forced to move outwards and push the steel plates together. With increasing pressure between plates, the friction also rises and therefore the driven gears are increasingly bind together and is more difficult for them to spin at different rates.

Plate LSD vs Torsen

Torsen differential uses gears instead of steel plates to transfer the torque on wheels. It is good solution for street driving with it's precise power distribution and stability on curvy roads. However, Torsen is not very suitable for high performance purposes, because it can't provide such aggressive torque transfer, especially under extreme conditions. As opposed, plate LSD is able to send power sharply to the wheel with grip which leads to improved traction and it's also more tunable than Torsen. Moreover, it works very fast and provides advanced handling even in the tight curves at high speeds.
