Sway Bar Opinions? R32 Gtr.

[Willis]

Yes. Otherwise your car will be stiff in bump settings but relatively soft in roll. Which is not a very nice combination because it wont absorb road undulations very well nor probably corner as well as it could.

So i want the stiffest swaybars i can find? Which as far as i know is Cusco?

Not necessarilly as spring rates can be a bit of a personal preference thing. But I would say that they are pretty stiff in the overall scheme of things. For what it is worth mine are about half what the Apexi rates are. It does depend on alot of other things, however.

Yeah you wont go far wrong with Cusco. They are better than the Whiteline ones because they are both stiffer & lighter. THe only reason I run a front Whiteline sway bar is as near as I can tell it is a little softer than the Cusco. But there is not much in it.

Hey, they may suit you just fine.

Was wondering about sway bars.

I have Nismo S-Tune Coilovers for my 32 gtr.

Nismo have an S-tune Swaybar kit to match the suspension.

For a street car, would it be best to have the nismo swaybars to match, or the standard whiteline one?

I'm leaning towards nismo - cons - almost twice the cost. Pro - matched by nismo + street legal without needing engineering (in SA at least)

Also I read somewhere that using hollow swaybars actually xfer the weight transfer better to a solid bar due to the ability of the metal to rotate upon its own central axis? (correct me if I'm wrong, I'm no expert), and also the solid ones are heavier - that said, being a street car I'm not particularly worried about weight until it effects my fuel economy ;P

Just would like to hear ya'll opinion before I shell out for the nismo bars - if theres a convincing argument to the contrary, I'll get the whiteline ones. I just don't know a thing about swaybars (aside from "they are good")

Logically the Nismo sway bars will be tuned to the Nismo springs whereas the Whiteline bars will be for the whiteline springs. If they have advantages for roadworthiness where you are from then you are on a winner. How much are the Nismo items?

Hollow bars & solid bars work in exactly the same way - the hollow bars however are lighter for the same spring rate.

$750 delivered for the nismo items front and rear, and around $450 for the whiteline. I reckon you're right. I'll hit up the nismos. Thx for feedback!

[kn6gtr]

do u know the diameter of the nismo items front n rear? im looking for swaybars atm and have nismo s-tune suspension in my 33gtr...

also do the nismo item come with link kit or do u just attatch to the originals?

1 last thing, wat site did u see the nismo swaybars on, i think thats a great price...

cheers

Website at RHD says 22/27mm swaybars, not sure about links

I saw them on RHDJapan - http://www.rhdjapan.com/nismo-s-tune-suspension-system-stabilizer-set-bnr32-bcnr33-bnr34-56105 this is the package they get bundled with the S-Tune shockers as well

Here is the standalone set - just need to save some dosh so I can buy them for my Xmas pressie this year heh

-D

Edit - incidentally I was wrong on the price, thats $750 not including delivery

Also - it seems the front and rear nismos are only a 1.2mm increase in diameter - whether they use a solid or hollow bar I dont know, or what grade of metal... not sure of how this all factor in...

A small increase in od makes a big difference in the rate - probably of the order of 20% in this instance (A rough estimate). The Nismo items will be hollow. The steel grade has little to no influence on the spring rate.

excellent, thanks for the input

Sorry to bring up an old thread but I thought it'd be better than starting a new one. I'm looking for a set of sway bars for my 32 GTR and was wondering if anyone had an opinion on what to get and prices in Melbourne.

At the moment I was looking at Whiteline adjustable's on eBay for $500 for the pair. This is purely a track car.

Oh and it has some shitty old Tein coilovers in it.

[GTSBoy]

Whiteline only offer the 22mm front and 24 rear adjustables anyway, so it's not as though you have as much choice as GTSt's do.

I realise that a GTR is a different car. On that basis I would expect that if you did what I have done (see below) then you might not get quite the same balance I have. This is especially true because the overall roll stiffness at each end is a function of the roll bars, the springs and the dampers, and of course these will all be different between any two cars unless set up identically. Notwithstanding that, I would suggest that being a track car, you would want lots of roll stiffness. Unless you are going to have very stiff coilovers in it, that means getting big bars. With no choice in sizing, you get the bars they offer.

My recent experience with R32 GTSt has been that 24mm adjustable Whiteline bars at each end are a good thing. I was concerned that there would be too much roll stiffness and the car would be skaty in the wet, but the opposite is true - it is just fine. I have mine set stiff at the front and soft at the rear - this is not from trial and error. The rear was set soft because I previously had a stock 22mm bar on the front and it was understeery. When I put the 24 on the front I left the rear alone. I really like the balance, so have had no reason to try different settings.

Further info. Stock R32 GTSt front bar is hollow 22mm. I can only estimate how thick the walls on it are, but given the estimate I made, the 24mm I upgraded to is at least 50% stiffer, possibly as much as 90% stiffer than stock. 24mm solid is only 20% stiffer than 22mm solid. If you were to get a Nismo (or Cusco or any other brand that offers something hollow) bar and it was hollow it would have to be a fair bit thicker than the 24mm solid to be any stiffer. I am aware of 27 and 28mm diameter bars from the Jap brands. These would probably be close to equivalent to the 24mm Whiteline bar. Given that you can only get a 22mm front from Whiteline, the Jap bars are probably decently more stiff.

I don't know if this has been helpful or not.

[gtr jet]

Thanks for the opinion mate. I get that all cars are different and that spring rates play a big part part in what bars to go with. Wish I knew what my spring rates were, they're pretty stiff what ever they are.

I guess eventually I'll just purchase the Whitelines and have a bit of a play to see what I like.
