R32 Gtr Sway Bars

[Godzilla32]

Hey guys, for those who have tried and tested. Is there much to be gained over the original R32 GTR sway bars with say whiteline uprated bars? If there is i may choose to replace them in my rebuild.

If i do choose to swap to aftermarket are the GTR bars any good to the GTS-t owners out there? If they are feel free to make an offer.

Rear bar will fit GTS-t but front wont as the front subframes are different (you have a front diff). The aftermarket whiteline swaybars are solid and considerably stiffer because of it (24mm rear is 147% stiffer than stock)

You also get the added bonus of having adjustment in the swaybars to adjust to the handling balance you prefer.

Ok thanks for the help mate, i appreciate it! So you suggest replacing both front and rear? Do you know what they are worth? Best place to buy them from?

Anyone want a GTR rear sway bar? Hehe, its already detailed up in satin black.

And yes, replace both front and rear otherwise it will not be balanced. Only having front bar will make it understeery and only having rear bar will make it oversteery.

good price and info. check him out.

i may alos be interested in your rear sway bar. what do you want for it?

[Godzilla32]

Cheers for the help guys. I'll look into this group buy. I wont want much for the rear bar...Make an offer i guess. It looks nice now all painted up in satin finish.

i have both front and rear available. (whiteline ones with the links). cheap. im really after the standard ones. so a cash adjustment will do.

theyre quite good. im doing some r and d.

The inherent problem with the Whiteline sway bars is that they are made from solid bar. There really isn't much excuse for making a torsion bar from anything other than tube....

more information?

It is true that hollow bars are much more efficient at handling torsional loads and therefore you can save 5-10kg from them. But they are much more expensive as hollow spring steal is not cheap, the range of sizes is limited and it is harder to mandrel bend (more expensive machinery is needed)

id like more info to but why would you need to mandrel bend them anyway?

sowhat is a better upgrade for a r32 gtst a GTR standard one or a whiteline?

[dead32]

it made sense to me so ill share my first thought on why it needs to be mandrel bend's, if you did not mandrel bend the bar it would create a weak point across the main flex sections of the stabalizer bar.

[salad]

If not mandrel bent, the cross section across the bar is not uniform and therefore stiffer in some sections than others.

The better upgrade depends on what spring and shock rates you are running. GTR rear swaybar is indeed a good value for money upgrade, but it is no where near as stiff as the aftermarket whiteline ones available.

22mm swaybar is 74% stiffer and 24mm is 147% stiffer. With the Whiteline bars you also get the added bonus (if you choose so) of adjustability.

[djr81]

By my rough calculation a solid 25mm anti roll bar is less than twice as stiff as one with a 2.5mm wall thickness.

Or to put it another way a 30mm od bar with a 2.5mm wall will do the same job as a solid 25mm bar for less than half the weight.

who does a/m hollow bars?

[djr81]

Good question.

[Beer Baron]

cusco do them for 32 GTR. justinfox has the cusco ones. ARC do them too. I'm sure there are others.

Not that I have seen.

Hollow stabiliser bars are horrendously expensive to make.

A few poeple have claimed to have aftermarket hollow stabilisr bars on their Skylines.

But when I check they are either solid bars or simply painted standard bars.

Not quite.

A 25mm solid bar is 191% stiffer than 25mm hollow with 2.5mm wall thickness, so almost 3 times as stiff

The 25mm solid bar is still 64% stiffer than 30mm hollow but the hollow is 23% of the weight. One way to have the same stiffness as a solid 25mm bar is to have 33mm OD with 3.2mm wall thickness. This bar will be 32% of the weight of the 25mm solid. There are endless combinations of OD and thickness that you can go through to make the same stiffness though.

All this is very interesting. So should i just stick with my hollow genuine items cuz they are lighter etc? Will the dampers/springs be ok as the only mod to inhibit body roll? It impresses me when i find out things like the hollow bars etc on the GTR are standard. It was a damn fine car for its day, not to mention now!
