Is It Sway Bar Time

[Deano 1]

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.

Whiteline adj swaybars was the best suspension mod i ever made

I'll have to me some, any advise on wat to set them at to start with??

And what to adjust to dial in more or less under/over steer??

[Risking]

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.

Ok just had a search around, these are the numbers I came up with, F=69 (7) and R=59 (6) I don't really understand what the 59 and 69 mean bit that's wat I got off the hks webby.

Anywhere anyone can suggest I get selby bars from? Online website? Or just repco it?

Thanks for everyones help so far

[Curmi]

also like to know this too....

whitline, i was going to purchase a set $440 delivered.

**Risking whats wrong with whitline sway bars?

I've installed a rear whiteline one and I used to understeer in my GTR. With it now I get a touch of of oversteer in the middle setting.

Great upgrade imo?

[lookingforboost]

pretty sure red ranger owns whiteline and selbys as far as i have been told by the supplier i get all my parts from they are the same?

[GTScotT]

AFAIK selbys have gone independant from whiteline/redranger now.

whiteline is now offshore whereas selbys is still local.

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.

can anyone sudjust a bar to suit my spring rates?

[Luke_ENR34]

Heres my new sway bars, Cant wait to test them out

[Curmi]

what brand are they? do-luck? they look nice

[Luke_ENR34]

Yep du-luck indeed. Shame they weren't cheap tho, good thing I didn't pay retail.

Don't think anyone else is running them tho.

Who did you buy them from?

[Luke_ENR34]

Found them on the jap auctions. Brand new but below retail. Usually over $2200 to buy.

[Curmi]

yeah some trader on ns was selling them for $900 second hand

[R32 DORI DORI]

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?
