I'm currently running a Sus Tech 19mm (I believe) on my DA and I want something bigger. I have been kinda looking but are there any other options for say a 22mm bar?

 

Not sure what's out there but I got something a little larger than a 22mm. ..like 10mm larger









Too bad it's not in production

How'd you get the exhaust past that thing?

cant u see the exhaust stopping right before the bar?

 

you can always run the pipes under the lca like those n1 style ones. but damn thats one beast of a sway bar.

 

It will clear the top, I havent had time to get it redone just yet....but it will clear.

 

not bein funny but is there any give in that at all?

or does the inside wheel just lift straight from the off?

 

The guy that built it put alot of thought in the design. It's not overly stiff. It is only 1520% stiffer than stock

 

Holy cow! That's crazy lookin. I will look for the Progress one!

It's hollow and hollow bars aren't the same in stiffness as a solid bar. So a 32mm hollow bar isn't anywhere near as stiff as a 32mm solid bar. You can't really compare it to a solid bar unless you know the torsional rates of both. Length and wall thickness of the bar all count too, as does how long the arms are.

 

didn't realise that people used hollow bars (although the thought did occur to me when 32mm was mentioned )

wouldn't a walled tube give more opportunity for fatigue and deformation? (although if the guy's got the figures to show it's 1520% over standard, I'm sure he knows his materials too )

and is that a bush or a bearing?

Actually it doesn't . If you look at the stressed areas of a solid bar when torsional load is applied, most of it is to the outside of the bar, this is the same as a hollow bar. The inside of the solid bar gives it a little bit more rigidity and strength, but not as much as you'd think. This is why you can have a hollow bar that is only 10mm larger in OD, but has a thin wall and is a higher torsional rate. Pound for pound a hollow bar will always be stronger than a solid bar (torsionally).

BTW: this info is from a book called "engineer to Win" by Caroll Smith. good reading if you want to know why parts break and how to make parts that don't break.

I'm not 100% sure but it looks like a bearing.

 

cliffs notes is that you get a bar that is as stiff and weighs less. (solid vs. a slightly larger hollow)

 

thanks, never thought of it that way - always good to learn (i never got to uni)

out of interest, what's the diameter of the (Uk 1.6i 16v) EF's OEM anti-roll bar? Is it identical to the DA6? or thinner or fatter (hopefully!)?
