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.

R33 GT-R Update: Nismo Strengthened Rear Lower A-Arm and Cusco Adjustable Pillow Ball Tension Rods

I actually installed these some time back but haven't had time to sit down and blog about them.

As some of you might well know, the GT-R is a 14 year old car and a lot of things get worn out as the years roll by. Hence, its imperative to refresh certain areas of the car, like the suspension, as it might pose a hazard to the driver and other road users. Its also a pain to drive around with a worn bushing or a less than functioning rear arm, as the car's ride tends to suffer as a result. More importantly, the GT-R's handling is much improved when newer and better suspension parts have made their way onto it's chassis.

Note the condition of the 14 year old Nissan factory rear lower a-arm - worn out!

This I can attest to after experiencing the before and after effects of something as simple as installing aftermarket adjustable tension rods. Its like night and day - suddenly you have the confidence to take corners at high speed and the car feels so much more controllable. The turn-in motion is also greatly improved and the car feels flatter as it pivots to where you want it to go. The rear also benefits from the strengthened a-arm plate as it's less affected by road irregularities and feels more planted when the car accelerates. 

All of this is multiplied in terms of driving pleasure as you get a sense of rightness about the car's condition and overall driveability. As I have said in previous posts, once you install one aftermarket suspension part, you'll be hooked and will have to the urge to change everything as a result of the positive effect they will have on your car.

The Nismo rear lower a-arm set looks right at home in the passenger side rear tyre well of my GT-R! :)

And so till the next suspension upgrade, I'll leave you with RHD Japan's description of the recently installed parts:

"The NISMO Rear Lower A-Arm Set - Strengthened R33 is part of the NISMO Suspension Link Series and were created by NISMO to provide true suspension performance for Nissan drivers. Included are the strengthened bushings to provide better feedback through cornering to make the vehicle more predictable. These are for true suspension performance, and are recommended to anyone using sport suspension and tires. The Nismo Strengthened Rear Lower A-Arms are a great way to refresh your vehicle`s suspension components by removing the aged arms that came stock from the factory. All units come in the Nismo silver color. These are stronger than the standard Nismo units because of an added plate on the underside to provide more strength against pressure and stress". - RHD Japan

"The CUSCO Adjustable Pillow Ball Tension Rods Nissan stop the movement and flex that change the geometry on the front suspension under hard braking and cornering and drifting. These Cusco Adjustable Pillow Ball Tension Rods help with stability and predictability when drifting or racing the car hard. They also improving initial turn-in response. They are designed to work with stock suspension or nearly every aftermarket system available". - RHD Japan

R33 GT-R Update: TEIN Mono Flex Suspension with EDFC

What can I say about the Tein Mono Flexes and the Electronic Damping Force Controller (EDFC)? Since that was quite a mouthful, to sum them up in one simple word - just plain AWESOME!

They've totally changed the whole feel of the car, and having the EDFC controller at your finger tips is just such a joy. They have once again made me fall in love with the R33 and I can't help but look forward to the next time that I'm behind the steering wheel. The feeling that you get is actually is quite similar to Audi's Drive Select in terms of damping and traction (Comfort / Sport / Dynamic). This very positive experience came as a pleasant surprise, as prior to purchasing the TEINs, I've never sat in a car that was equipped with TEIN Mono Flex and EDFC.

PIMPIN, a fellow Skyliner who owns a BNR34, is an ardent supporter of these two TEIN products... so much so that he has installed the Mono Flex / EDFC combo in all of his previous rides (including the R34 GT-R)! Even with that sort of endorsement by a close friend, I was still a bit sceptical. I was worried that the TEINs would be stiffer than my old HKS Hiper-Ds - even at it's softest EDFC setting. As for the HKS suspension, I've never been happy with them because the Hiper-Ds are VERY bouncy on less than perfect roads (poor damping) and they don't inspire confidence when taking sharp bends or corners (very floaty to say the least).

Now my main concern was that at first glance, the spring rate on the MonoFlexes are EXTREMELY high. So one would immediatly assume that the ride would be harsher (case in point, the side by side pic found above). Before I go any further, lets have TEIN explain a little bit more about their Mono Flex and EDFC:

The MONO FLEX coilover kit has been developed for entry-level competition motorsports and advanced street driving. Features include 16-way damping force adjustability (combined compression and rebound), a mono-tube internal design, pillowball upper mounts, and EDFC compatibility. There are independent adjustments for ride-height and spring pre-load settings for increased suspension tuning. The new Mono Flex also includes TEIN's latest technological innovation, Micro Speed Valving (MSV) system, which allows the driver to feel a greater difference in damping force adjustments. Designed and developed for consumers seeking aggressive handling on the street and at the track.

The EDFC (Electronic Damping Force Controller) makes it possible for the driver to control the damping force at the touch of a button while in the driver's seat. This is accomplished by controlling stepping motors installed on each shock absorber. Because the damping force can be controlled with such ease, the driver can adjust the suspension to suit all road/track conditions. Thus allowing the driver to fully enjoy the driving experience.

By inputing your preferences into the controller, the new setting will be transmitted instantaneously to those little small boxes that you see on top of all four of the TEIN suspension mounts.

I found out very quickly that setting the EDFC to 0 Front, and 0 Rear resulted in you feeling EVERYTHING on the road surface. Sort of like dragging yourself naked across the street. This prompted me to increase the settings to 12/14. Immediately, the harshness subsided. TEIN did an unbelievable job with their spring and damper design, which resulted in the production of the MonoFlex. With the settings at their softest (16/16) I was able to experience a near stock like ride quality at low speeds. Of course, the same is not true when I bumped the EDFC up to 0/0 once again. You felt everything, and it hurt. Definitely not the sort of setting that one would want when cruising down inner city roads. On smooth highway asphalt though, the 0 / 0 literally blew me away. I could easily carve corners at significantly higher speeds than I ever did with the HKS Hiper-Ds. The TEINS seem to make the car that bit more predictable and gave me the confidence to push the car slightly closer to the limits. They also help in the traction department especially when launching the GT-R, as the rear is squats easily due to the softer damper.  I reckon 0 / 0 would be superb on a track like Sepang, where you really get to test the TEINs to the maximum of their ability.

HIGHLY recommended.

Rainbow tyre well thanks to the yellow of Whiteline and Goodridge, blue of Cusco and green of TEIN. Soon to be joined the matt silver of Nismo (strengthened lower rear A-Arm).

R33 GT-R Upgrade: Cusco Adjustable Rear Upper Arms

Suspension upgrades are like a bowl of delicious french fries. Once you start, you can't stop consuming / installing them. Seriously addictive. 

This isn't an act of superflous spending on my part, for as I have said in my previous entry, the rubber bushing on most of the GT-R's factory mounts are in a poor state and therefore need to be replaced. They have after all been on the car for the past 15 years! Hence, this is more of an exercise in necessity instead of greed.

Once I had swapped in the Sun Line Racing Front Pillow Camber Arms and felt an instant improvement in the GT-R's handling, I decided to plunk down some more moola on a used set of Cusco Adjustable Rear Upper Arms. Thanks to Eu Jin from JDM Auto Link for supplying the said item which looked near brand new.

So whats so great about the Cusco unit? Well, the overall benefits are very similar to the Sun Line Racing arms but I'll let RHD Japan explain further:

"The CUSCO Adjustable Rear Upper Arm Links Nissan will provide proper camber angle and improve you cars movement in hard turns on the track. Prevents irregular tire wear and holds tire to the asphalt, improving traction. The good alignment will enable better traction as well". 

 The Cusco rear upper arm and the factory Nissan unit - the bushing too was pretty worn out

The Cusco unit installed on the driver side rear wheel well

Remember what I said about suspension upgrades and how its hard to stop oneself from installing more? Well, I've ordered the following items and they'll be arriving some time soon from Japan :).

R33 GT-R Update: Sun Line Racing Front Pillow Camber Arms

In preparation for a drive up Fraser's Hill, a former colonial-era hill station in the state of Pahang (more info here via Wikipedia Travel), I sent the GT-R in for a suspension realignment.

I had noticed that the car would slowly veer off to the left when running in a straightline, in the absence of any steering wheel input. It turns out that my front upper camber arms were out of whack. The realignment guy said that the bushings on the factory arms were probably worn out and I believed him, seeing as they've been on the car since it left the factory in 1996! Thats some 15 years ago!

So the task for that day was to look for a replacement front upper camber arms, preferably adjustable ones. Why adjustable you might ask? Well for one, it allows you to set the car up for more negative camber and this is always good for track days. It makes it easier for the car to go around corners and it promotes better tyre wear. Some of you might recall that I changed all of my old factory suspension bushings to Whiteline ones, when I first got the GT-R. I should have looked at replacing the arms too, both front and rear. Chalk it up to inexperience!

Now I live in Malaysia, so GT-R parts are not that easy to come by. According to my tuner, the golden age of GT-R ownership in our fair country was some 5 years or so back, when parts were readily available. The R35 GT-R had not arrived yet and vendors heavily stocked up on BNR34 parts, which mostly are plug and play for BCNR33s. So without some effort, I managed to source a pair of used Sun Line Racing Front Pillow Camber Arms. Least I think they are Sun Line Racing units... After inspecting the arms, my tuner said that they were clearly of Japanese make and hence, were worth buying. Anyway, one can't be choosy when supply is short and time is of the essence. What was important was that the arms were adjustable, the rubbers bushing looked pristine and the pair were clearly of superior make.

Now whats so great about the Sun Line unit?

 Heres an excerpt from Nengun:

• R33/R34 model includes four stage camber adjustment, ranging from standard to about -2 degrees
• Camber adjustable highly accurate specific pillow ball

The alignment guy was spot on. These are my old, non-adjustable front upper camber arms. Note the very poor state of the rubber bushing:

Side by side comparison between the new and the old:

The GT-R was sent back in for another round of suspension realigment after the Sun Line arms were installed. Upon taking delivery of the vehicle, I immediately noticed that the car would no longer slowly veer off to the left. Turn in and cornering had also improved - not really surprised, as the dilapidated factory ones were probably slipping, due to the very poor state of the rubber bushings. 

So I was very happy with how things turned out. So happy in fact, that I decided to get Cusco Adjustable Rear Upper Arms and Tein Tension Rods after the Fraser's Hill drive. Will write about these two mods in my next R33 GT-R update.

I've been officially bitten by the aftermarket suspension mod bug!
