Signature or Whiteline Sway Bar? Feedback Wanted!

Hi! :D

I'll be ordering either a signature or whiteline sway bar from mania next week.

I was really after the racing beat one, having had most of its design and testing around minimizing oversteer that was a problem in the '01+ NB. But by the time it ships here it will be twice the price.

Are they all the same, and everything else written is just sales pitch?
Or is one better than the others?

They're all adjustable.
They're all available in the same OD... I think?

Any pointers would be great!
:beer:

:? what?

if you want to reduce oversteer, try removing your rear sway bar.

Willstar is referencing this: http://www.racingbeat.com/Miata-1990-20 ... 54106.html
Our testing has shown that each model of 2001 Miata that we have dríven has shown a tendency to power "oversteer" at low speeds.. Each car exhibited a tendency to oversteer at low speeds (under 40MPH) upon acceleration.

Yes that's the rundown on other discussions that ive had.

Here's racing beats full description of it.
2001-05 Miata (Intended Application)
Our testing has shown that each model of 2001 Miata that we have dríven has shown a tendency to power "oversteer" at low speeds. (The models tested include a base model with a 5-speed transmission, a LS model equipped with the 6-speed transmission and Sport Suspension package, and the LS model equipped with replacement KONI shocks.) Each car exhibited a tendency to oversteer at low speeds (under 40MPH) upon acceleration. Inquires with Mazda have failed to identify any specific changes to the 2001+ Miata chassis that might account for this handling trait.

As a result, these findings led us to develop an even larger front sway bar for the 2001-05 Miata. The use of this larger bar (and retaining the stock rear bar) has neutralized most of this oversteer condition at low speeds, and allowed the Miata to exhibit a small amount of understeer at higher speeds. The use of the Racing Beat rear sway bar would negate the benefits this larger bar, and is not recommended. While the smaller 1.125" OD tubular bar we also offer can be used on the 2001-05 applications, we recommend the use of the larger bar.

Pretty much. Sure the metallurgy may be different, and the manufacture process may be different, but once fitted, the different is negligible. It's not exactly a fine art in this respect.

As for same OD, THIS you have to take note of. For example, RB has a very large OD hollow bar that is stiffer than their smaller OD solid bar, so don't go my OD to make a choice, make sure you know it's actual structure and stiffness rating.

Also bear in mind, Signature bars are made by Selby.

Which used to (still does?) make Whiteline bars.



I'm pretty sure I remember reading that.

I ordered a Whiteline front adjustable bar and found it would not fit an NA6 - it was not designed to work without new end-links plus would easily foul on suspension points.

I changed to a non-adjustable bar and it works fine.

My advice would be to check that you can return or exchange anything you buy as the adjustables may require new end-links plus it may foul if not correctly designed.

Here comes the no BS answer, NitroDann style.

Its a frikkin bar. And a primary school child can do the required maths to fins what bar will do what to the handling.

Do you HONESTLY find yourself oversteering everywhere in 2nd, accidently?

Or are you looking for something to spend money on, and it seems this part 'fixes' the 'problem' your model apparently has?
If you just want to spend money then buy anything, you will never tell the difference.

However if you find yourself at the limit of grip constantly and at 2nd gear speeds get undesired oversteer during this time, go to the solomiata calculator, punch in the numbers, and find the bar that suits and buy it.

Or remove the rear sway.

That wasnt NitroDann Style!

That would include the fact that you could bend the perfect one up and sell it to me for $50 shipped!

:P

Learn to drift,or
Buy stickier tyres,or
Remove rear sway bar,or
Increase front sway bar rigidy,or

gslender had some good advice regards product buying, especially when buy a front sway bar. rears always seem to fit good. but fronts are a little hit and miss.

I had a Selby adjustable front sway bar and a unbranded adjustable rear sway bar on my last 5. The rear sway bar was of a smaller diameter than the standard. I don't know the size of the front bar. I had rose jointed adjustable end links, which as mentioned above is the only way you can use the hardest settings. I also had tein flex dampers fitted to that 5.

Anyway to my point. I now have Yellow coilovers on my current '94, with standard sway bars. In the short time I have had the Yellow coilovers fitted I am surprised to find that my 'want' for upgraded sway bars has somewhat diminished. Of course my 'Darryl' wheel alignment probably has a lot to do with this.

You are welcome to take my 5 for a drive if you want something to compare with.

Also be aware that this can happen if you uprate the front swaybar:

That's a pic from my NB8A.

I would really like to, and I am sure there are a few other members here that would be interested, see those primary school calc's dann. Elementary stuff shouldn't be too hard to type up.

OP - People have had issue with front adjustable whiteline sway bars.
