Confirming what salad said. The hole at the very end of the bar is softer, the one closer in will make the swaybar act 'stiffer'. Try them both to see what you like. Also depends on the way you're driving and the rest of your suspension setup.

You actually have three settings even though there are only 2 holes either end.

Soft - both holes cloest to the ends of the bar(outer holes)

Medium - one outer hole and one inner hole

Hard - both inner holes

The bar does not have to be balanced - it is simply a torsion bar determined by length.

From Whiteline themselves

Asymmetric is the opposite to symmetric and implies the use of differing holes on each side of the swaybar. For example, this might involve setting the left hand side to the hardest setting of 3 while the right hand side might be set to the middle setting. Contrary to what some people think it does not equally split the rate difference between symmetrically using setting 3 and setting 2. That is, the resultant rate is also asymmetric with more roll stiffness on one side compared to the other.

You can do it, but it's probly not the best

Jim and I are still debating this one, he tested it on the Whiteline test rig and found a difference. I use split settings all the time and haven't found one driver who can pick any side to side difference.

A stabiliser bar simply links one wheel to the other wheel on the same axis, so anything you do to stiffen up one arm must stiffen up the other. This is how most race cars adjust their anti roll, by rotating the blade (arm) on one side of the bar. The fact is that this adjustment results in equal and linear increases/decreases in anti roll.

The question (and the debate) therefore can only be about the geometry of the links when different holes are used side to side. Based on real world testing, on a Skyline that effect is very small on the rear and basically non existent on the front.

Moving on to settings, there is no right or wrong in stabiliser bar settings. It is a personal choice, you set them the way that feels best for you. Personally I would start with the front on the middle setting and the rear on the softest setting. But have a play around, see what you like, that's why you spent the extra money so that you could adjust them.

:D cheers :D

PS; the Group Buy stabiliser bars come with additional adjustment holes over the Whiteline retail product.

are the stock sway bars on the R33 GTST much softer than the group buy?

maybe I'm just getting used to decent handling, as my R33 sits flatter around corners than any other car I've been in - although it hasn't been on the track yet :)

No idea whether the bars are stock or not, I'll get underneath and measure the diameters of the bars

From stock, the front bar is 21mm hollow and rear is 16mm solid. So, the front bar is roughly 200% stiffer and rear bar is 60% stiffer.

It's a bit hard to tell the exact stiffnes of the front bar as the stock one is hollow and the ends aren't just squashed pipe like others. I have made a guess at the wall thickness going by an S13 and R32 GTR swaybar.

EDIT, just noticed you have R33 GTS-t, I was going by stock sizes on R32 GTS-t. Post up the stock R33 swaybar sizes and I'll work them out for that too. Also tell me if the bars are hollow or solid. You should be able to notice by the weight of them and what they sound like when you tap them.

Staggering the adjustment is a two edged sword. The Best advantage to the stagering of the sway bar settings we have found is this.

Because a sway bar applies mechanical pressure to the spring (which loads it up more) in a corner, it is often used to help flatten a car during the cornering process. We have found that staggering the sway bar (soft setting on on side/ hard on the other) that it is possable to 'tune' the suspension a little better to suit a particular track. This helps tyre wear, car balance and other such things. This helped when on a left turn track. (more turns left than right, or vise versa)

By swapping the staggers around, we found the vehicle tended to understeer more in some corners. On the street, i would recomend not staggering the bar for this reason. The car tends to be a little vague when turning one way as opposed to the other. Its because the leavering effect.

But at the end of the day, try it.. and be aware of these things.

Any other thoughts. :)

    • Ok i will get those 310mm. I found one but on a different site. This is the description on those...is it ok? Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
