Willall Racing Launch GT-R Rear LSD Upgrade Kits

December 16th, 2010

Willall Racing WR35DS

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…

OS Giken Extend Range of Rear LSD Upgrades for the Nissan GT-R

February 12th, 2010

Some time back Sunline Racing worked together with well known Japanese manufacturer of all things clutch and LSD related, OS Giken, to come up with an improved rear LSD for the R35 GT-R. The result of this partnership was the OS Giken OS-TCD LSD. This flagship product is a easy to live with but high performance LSD in the OS Super Lock LSD range. It features unique oil control systems to ensure that all of the friction plates are kept lubricated all of the time. The result is a smooth performing LSD with extreme high performance capabilities which led Sunline Racing to shave seconds off their laptimes at the track.

The OS-TCD may be the ducks guts rear LSD but it comes at a price of 300,000 yen in Japan before tax.

OS Giken have now developed a less intense but still better-than-standard performing upgrade rear LSD for the GT-R known as the OS-NEO. The NEO is designed for daily driver GT-Rs who see some performance street driving and track days and are looking for a bit more predictable traction from the rear out of the turns without the interference of VDC. The NEO will set you back just 191,000 yen in Japan before tax.

OS Giken are also pegged to release a front LSD upgrade for the GT-R in coming months. This will compete with existing offerings from HKS Kansai.
