Lean Less: The Inside Scoop on Anti-Roll Bars from GRM

I thought I knew everything I needed to know about anti-roll bars. This article taught me a thing or two I didn't know. If you think adding a 1mm thicker bar won't make much of a difference, read on...

Excellent article. I wonder if SVT knows approximately what the precentage is for the stock TLLTD. I'd be interested to see what the H&R 24mm rear sway bar does for that factor since that's most likely the sway bar I will upgrade to. And I wonder if the moment arm is different in length than the OE.

Just as an interesting side note, Sway-bars are used by manufacturers in very different ways. BMW for instance, believes in stiffer springs/dampers with relatively weak sway-bars whereas Lotus uses a lot of sway bar with a relatively soft damper/spring setup. Both are great handlers, but shoot for the same goal with different methods.

So many people forget how much of an interconneted system it all is, but of course not many companies would sell (or customers would buy) nothing but a front to back full suspension upgrade... After all, even an upgrade in tires could totally change the TTLD.

Adjustable endlinks??

Is that a question or what? I know there are adjustable end links on some sway bars, but as far as I know, H&R's are fixed. I was stating I wonder if the moment arm on the H&R sway bar is the same as OE which would mean you'd only increase the stiffness of the bar through the diameter enlargement - not the moment arm increase in length and the diameter.

Oh wow, so going to a 24mm H&R bar is going to make a WORLD of difference. Now I can see how just adding to the rear can disrupt the cars balance so much.

if the HR bolts back up to the stock location with the stock bolts wouldn't the arm length be the same??

Not necessarily. The location of the bolts and mounting points for any aftermarket sway bar should match up to the OE unless fabrication is required. If the H&R sway bar were to have a longer moment arm, all it would simply do is readjust where the bar is located under the car by possibly a few centimeters. Basically, if you can imagine the OE bar is fixed but has some space around it, then the moment arm of the aftermarket sway bar can be lengthened or shortened as it has room to be moved forward and back in the empty space.
