 Post subject: SH Rear Swaybar - 22mm vs 24mm

So first a rant:

If you don't have an item in stock, don't list it for sale on your website. If it's on the website, and there's no note saying stock levels to be checked before ordering, then a reasonable person would assume that its in stock.

Very frustrating to place an order and then be told, 2 days later AND after the money has been taken that "sorry, your item is on backorder and won't be in until August".

It's 2018. If you don't have the item in your warehouse, say so. And maybe confirm before taking my hard earned if it's not on hand?

End rant.

So, the actual point of this post:

If I'm looking to buy a rear swaybar for our SH XTP, how much difference is there between the adjustable 22mm whiteline item and the 24mm adjustable whiteline item?

I was aiming to buy the 24mm item. But I wasn't really wanting to wait until August to buy it.

Keen to hear from people who have used both.

Currently the car has no other suspension modifications.

I have some nice solid endlinks on the way so they are sorted.

Cheers all.

Two millimetres

:P

I have the 22mm items and and am pretty happy with it.

Two millimetres


Its actually over 72 mm^2 of additional cross sectional area. Or nearly a 20% increase in cross sectional area.

The strength of a sway bar doesnt care about diameter. It cares about CSA. And the CSA increases exponentially relative to diameter. (This is just like how the volume you can flow through a pipe increases exponentially with diameter.)

The difference between an 18mm and a 20mm swaybar is different to the difference between a 22mm and a 24mm swaybar. Even though they both only increase by 2mm diameter.

Ok, so applying the CSA theory...

Stock = 16mm = 201.06mm^2
22mm rear bar = 380.13mm^2
24mm rear bar = 452.39mm^2

So would that mean that the 22mm RSB is approx 190% stiffer than the stock 16mm RSB. Nearly double the stiffness.

Then the 24mm RSB would be 225% stiffer than the stock RSB?

Therefore, would that mean there is a 35% difference between the 22mm and 24mm?

So... how much difference really is 35%?

35% more engine power is amazing. So I guess the same would apply to handling.
I have a whiteline 24 in the rear of mine. Car handles very well.

I think I did read somewhere that it is a hollow item. Not 100% sure though.

I have the 22mm adjustable and with MY08 STi struts/springs - very happy with the 22mm. Couldn't tell you how much better/different a 24mm would feel but there's enough stiffness in the rear end to make the car want to rotate a lot better, whilst staying much flatter in the corner.

I have 22mm rear swaybar in my SG and find it too stiff. And a 25mm front bar which is quite nice.

Any other suspension mods to your car mate?
