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.

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?

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.

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.

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.

:pirate: cheers :kiss:

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!

    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
    • On the bright side, the weather will turn much nicer for working outside shortly....sounds like you might need to start on a neighbour's garden next
