Well I've picked up a set of whiteline adjustable swaybars and was wondering what settings people run them on, I've done lots of searching here and it didn't come up with much on matching the adjustable's (but there was a nice table on miata.net for thickness matching).

So if you could post up what you run and how

for 3 settings use soft, medium, hard (soft being the one closest to the end of the bar)
for 2 settings soft or hard

Car: (NA6, NA8, NB8A, NB8B, NB8B, NC)

Front Bar: (brand/type)
Front Setting: (soft, medium, hard, or none if not adjustable)
Front Thickness: (even if it's adjustable, and if it is hollow or solid)
Rear Bar:
Rear Setting:
Rear Thickness:

Comments: (oversteer, understeer, low speed oversteer, bit of both, anything else you might want to add)

If you only have one bar then put "stock" in whichever field it is
If your running stock front and back then don't bother
And if like Stan your running swaybars from different models then post it up as well.

Thanks in advance to anyone who replies, especially if they have an NB with whitelines

Car: NA8
Front Bar: Racing Beat
Front Setting: non-adjustable
Front Thickness: 23.5mm, solid

Rear Bar: Whiteline
Rear Setting: Medium
Rear Thickness: 12.5mm, solid

Comments: Mostly neutral, but understeers slightly when pushed hard around sharp, 120degree or more acute, corners.
Keep in mind I have Eibach springs and Koni dampers set to fairly hard, so they exarcebate the handling characteristics when installing harder sways.
Previously had Whiteline 22mm non-adjustable front bar, and it was better balanced, and quite luverly in the wet, eh Fatty?

Car: NB8B SP
Front Bar: Whiteline
Front Setting: non-adjustable
Front Thickness: 24mm, solid

Rear Bar: KMac special order
Rear Setting: non-adjustable
Rear Thickness: 14mm, solid

Comments: Originally fitted with stock springs and dampers. Great bang for your buck mod. Makes the car feel a bit more planted on the road without turning it into a kidney busting go-kart. I originally had the Whiteline 16mm adjustable bar on the rear but even on the softest setting with SP power I found it oversteered a bit more than I wanted it to. I switched back to the stock 12mm bar and it turned into an understeering dog, especially in the wet. Switching to the 14mm bar meant there was a bit less oversteer and the handling was more neutral than with the 16mm bar. The bars were my first suspension mod and started to turn the to softly sprung NB8B back into an MX5. I have since changed the dampers and have to admit that they made a much bigger difference than the bars. But if you want to tighten up your MX5 a little without upsetting the Mrs and tune the handling a bit to suit your driving style and your on a tight budget the bars are a great place to start.

Car: (NB8A)

Front Bar: Racing Beat
Front Setting: Hard
Front Thickness:Tubular .125” OD (31.75mm)
Rear Bar: Racing Beat
Rear Setting: Soft
Rear Thickness: Solid 5/8-inches (15.8750mm)

Comments: I have my rear dampers set harder than the front to reduce overseer, seems fairly neutral on the track but I need more time to test.

This thread would be more useful if it included spring rates too......

I run monoflex shocks with a 7kg/6kg Front/Rear setup.
Signiture adjustable front 24mm on the standard endlinks at hardest.
Signiture ajustable rear is a 16mm unit on medium but I put adjustable rear endlinks on it and pulled a little bit of pre-load off them.
I run 8 off full hard on the front and 12 on the rear for the shocks with an EDFC.

Cars feels awesomely neutral in the dry but extremely oversteery in the wet.

would hard/hard to too stiff with stock nb8a suspension?

also difference between whiteline and the signature bars?

You can only try and find out! I ran hard/hard for a bit on my NB8A (admittedly I have super streets) but found it wasn't quite as balanced as I would've liked, so I think I put the rears back to medium.

As for a difference between the two bars, as far as I recall there is no difference physically. They even come out of the same factory, so I've been told (or at least used to?). I went the signatures because they were cheaper and they come powder coated in certain colours. Green sways match my green MX

Depends on the stiffness of the bars, as all manufacturers have different stiffnesses even though they are the same diameter.

If Whiteline and Signature are from the same factory, then that would be Selby's

That too sounds familiar.

And Don Selby bent my Pedders adjustable bars for my NC....

Car: 2002 NB8B

Front Bar: Whiteline Adjustable
Front Setting: SOFT
Front Thickness: 24mm Solid
Rear Bar: Whiteline Adjustable
Rear Setting: HARD
Rear Thickness: 16mm Solid
Shockers: Standard
Springs: Tein S Tech Coils
Spring Rate Front: 336lbs
Spring Rate Rear: 252lbs
Also have a Carbing Alloy Rear Strut Brace fitted

Comments: Car did perform better than standard, felt much more stable and planted on the road, but still under-steered more than I liked when I was driving at medium pace to hard in dry weather (No wet weather experienced, but I would assume it would under-steer horribly, considering how much it did in the dry). So I adjusted the front swaybar setting to SOFT and it now handles like a dream, it over-steers only slightly when pushed hard, if the car had a bit more power I could quite easily hold a decent slide on the current settings, if dríven properly, it is superb, car communicates much better, great addition to an MX5 it just doesn't stop holding unless you plant it

Cheers

Car: NC

Front Bar: Whiteline
Front Setting: hard
Rear Bar: Whiteline
Rear Setting: soft


Comments: understeers at low speed, rear end breaks into a nice and controllable drift at higher (60km/h+). Good if you like heavier/ meatier steering.
