S13 Update: Nearly Track Ready

The S13 is nearing completion - and not a moment too soon. For this Saturday, I'll be attending a closed track day at the Sepang International Circuit :).

With the engine rebuild completed, I shifted my focus to the car's handling. The S13 was still running stock sway bars. After installing a full set of Hard Race suspension upgrades (pillow ball tension rods, lower rear arms, rear camber kit etc), along with Nismo bushings and solid sub frame collars, the old bars just wouldn't cut it. The rear felt very solid and the front somewhat weak. This might affect turn-in and promote understeer. As such, it needed stiffening and the stock bars were just too skinny. That's why I opted for a full set of front and back Cusco stabiliser bar kit. They arrived from Japan and here is the reason why they are going onto the car:

Cusco Stabiliser bar kit for front - (P)S13. 28mm diameter (Standard is 24mm). 131% stiffness comparison.

Cusco Stabiliser bar kit for rear - (P)S13. 18mm diameter (Standard is 16mm). 114% stiffness comparison.

Along with the Cusco bars, I ordered Nismo Braided Clutch Hoses for both the S13 and the R33 GT-R. Compared to the factory stock rubber hose, stainless steel mesh was adopted by Nismo for a much lower rate of expansion. The Teflon interior of the pipe provides a low pipe frictional coefficient and smooth flow volume characteristics, for more direct clutch operations. So in other words, there is no room for volumetric expansion. Not only will the Nismo braided clutch hose firm up pedal feel but it'll also make the clutch function precisely, by not allowing the hose to swell and lose pressure.

Now all that's left is to upgrade the car's suspensions. It's currently running JIC high lows and as some of you might know, you need fully adjustable suspension for the track. I'm looking at buying a used set of Aragostas but at the sametime, quite keen to see what RCS - Radical Chassis Solutions - can do for my ride. It's headed by Nanda Kumar, who has some 15 years of experience in rallying. According to a review by Tom of Zerotohundred, Nanda was trained by Lotus Engineering and has served as an engineer there for some years. So, he probably knows a thing or two about suspensions, and handling, of the Lotus kind.

More updates to come, so stay tuned :).

Review: Whiteline Performance Suspension

Since I'm a big supporter of Aussie made automotive products, I've decided to write a couple of short reviews on a few of them for the benefit of the Malaysian motoring public. Besides Whiteline, theres Haltech for your electronic engine management needs, Disc Brakes Australia (DBA) for rotors and Turbosmart for wastegates. The Aussies make pretty decent stuff and I'm using all those brands in my cars.

As some of you might have noticed, I am currently using Whiteline Performance Suspension bushes and sway bars on my GT-R.

I actually started using Whiteline on my cars since my student / working days in Melbourne, Australia. Great people to deal with over the phone and easy pick up at your friendly neighbourhood Pedders Suspension shop (they have a tie up with Whiteline). Pedders is a chain of suspension tuning shops which can be found in many Australian towns and major cities.

Anyway for everyone's knowledge, Whiteline suspension suspension products are actually manufactured in South Korea but design and testing is done at their facility in Somersby, New South Wales (near Sydney). Whiteline recently had their swaybars TÜV SÜD certified, so that they could be sold in the EU. They are pretty much up there in terms of quality seeing as European standards are quite stringent when it comes to automotive parts.

As with most automotive parts, a company's product is as good as how well it does in motorsport events. Whiteline parts are used in major events such as the recent World Time Attack Challenge (WTAC) that was held in Australia. A Whiteline equipped R35 GT-R took the number one spot in the Open Class category and several cars in the Pro Class (like Mercury Motorsports' R35) used Whiteline swaybars. Whiteline parts have also found their way into the rallying scene. WORKS Motorsport's Mitsubishi RalliArt SST participates regularly in Rally America, The Oregon Trail. Whiteline has been supporting the WORKS car with adjustable sway bars, alignment products, polyurethane bushings and aluminium bushings.

I'll leave with you some pictures of Whiteline's NSW facility. If you're looking to improve the handling of your car or wanting to refresh tired suspension parts, check Whiteline out as they cater to a wide range of makes and models, from Subarus to Volkswagens.
