Here’s another good idea from Aussie workshop Willall Racing. Instead of ditching the entire rear LSD assembly for a fancy aftermarket job they’ve decided to beef the stock one up to the task. With the goal of making the OEM LSD good enough for circuit abuse they reckon they’ve achieved it with as little as their new WR35DS Rear LSD Super Lock Kit.

Given that the stock diff is a high quality, well machined 1.5 way item with solid steel assemblies to begin with – it made sense to at least have a look in this direction.

This series of hardened and heat treated differential shims is installed to adjust the pre-load on the factory diff to the owners liking. You can go from “mild” to “wild” depending on how many shims you use.

The end result is significantly more grip and an end to the inside wheel spinning during cornering. A good result for the price of just $395. Click the link below for more info…
