Hi all, car = 32R

been starting to do trackdays and they gunna get more offen soon as my new wheels come so I can wrap em in semi's.

My car has HKS hyper max 2 coilovers, tein castor rod, tein rear camber adjusters but factory swat bars. I was thinking of geting a front and rear adjustable whiteline. Would it be worth it? Make it sit flatter around the bends.?

Another thing I noticed at the track last time was alot of people with 32r just changed the rear swaybar not the front one, any no why? Should I change both?

Cheers deano

Since GTRs understeer a lot you want to have a stiffer rear bar to dial some of that out - so that's why those guys are changing that end first. Having adjustables means you can change the understeer/oversteer balance by changing the stiffness. I did both ends in adjustable whitelines. They're pretty cheap so i did both at once.

Dont buy whiteline.

Do yourself the favour and buy SELBYS, get blade type adjustment too.

do you know what spring rates the HKS coilovers currently have??

From there bar diameters can be advised a little more accuratly from experiance.

The method is simple to begin with. Medium all round perhaps a little less bar on the front if anything. If its oversteering more bar up front, Understeering more bar at the rear.

There are way to may variables to set a car up perfectly with advise and to alot of people sway bars are a placebo that makes them think their car is handling better, same can be said for spring rates.

The best way is to attend an open practice day armed with a trolley jack and some tools. Make bar changes each session. Drastic changes at first so you can identify what effects it has on the car. Then minimalise the changes as you gain experiance with the bars effects and your knowledge of interperating a cars behaviour increases.

There is nothing like experiance when it comes to car set-up.

You need to spend hours if not days deliberatly making massive changes to the car be it good or bad. That way you will have a far better seatometer as I call it to gauge a good handling car compared to a poor one or an average one.

Once you have the handle on big changes make them smaller and smaller till your stuffing around with very small allignment and geometry changes. It can actually be alot of fun if you are commited to trying it.

The 7 refers to the spring rate in kg/mm. The 69 refers to the spring rate in Newtons per mm. 1kg=9.81 Newtons.

With those spring rates the Whiteline bars will struggle to have an influence. Added to which they are heavy because they are solid, ie rod rather than tube.

They are the same, bent in the same factory.

Or at least they were up until a year ago.

Slight thread hijack but since this is about sway bars this is my best bet.

My R32 GTST understeers like its going out of style, in the rain I may as well just not turn sometimes. Its only on standard rims ATM so there are all of 2 inches wide (slight over-exaggeration) But I'm moving up too 8 iches up the front soon.

Tyres are of good quality and a decent brand unlike the rears. Next planned buy for my baby is a set of decent sway bars.

What would you guys suggest?

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
