The adjustable rear bar isn't exactly a huge moving option. I've thought about an adjustable front, and might still do it--but it's not at the top of my priority list right now.

As for fitting the Hotchkis bar--really I have no reason. I have no issue if someone wants to try one, but when I have something that is a known commodity that solves a particular issue I don't have much need to find new ways to make that wheel round.

I *know* the bar I helped with fits and tweaked things like bushings and such to make sure it clears the Watts, and sooner or later you'll see a hollow rear that's also adjustable from me (been on the books, just not had the time), and it'll be less than the Hotchkis which still seems to be vaporware. Weight difference is about 8 pounds (but a stock bar is in the middle, just my hollow is a bunch less).

So today I found out (for comparison with the adjustable 15/16" bar) that the hotchkis non-adjustable 1" rear bar (This is what I have in my car now) has a
255 lb.in. spring rate. So it looks like the adjustable bar would take me in the right direction.

I guess a Watts link will be the top of the list. Sam, please make the adjustable front and rear happen sooner.

So did you try to do the math or did you have to call the manufacture? Are you sure those numbers are right? Seriously, it's just simple algebra, do the math. Don't you want to validate the manufactures claims? This is the whole reason you had to start this tread 3 times.

First of all I don't know the I.D., or the length, and as far as the math I haven't used any algebra like that in over 20yrs.
So if you can answer my questions that would be great!

And the only reason I had to start this tread 3 times is because you deleted the first two threads completely; by the way,thank you!

Does anybody have it yet, opinions?
It's a lot like the Hellwig (3 position) adjustable rear sway-bar, except it's hollow, and a 15/16" bar.
It's 3 Adjustment Settings are, 225,240,255 lbs/in;but I have no idea what the equivalent sway-bar size in millimeters is for each position.

Well I guess you shouldn't have posted up links, coupon codes or pricing to a non-sponsor link.

Now since basic math is too tough for you, and your ability to reason that the arm length must be extremely close to your current bar in order for it to fit right let me give you your answer (And BTW, it's been 20 years since I took Basic Algebra)

Hotchkis Adjustable Rear
225: Acts like a: 21.49 mm
240: Acts like a: 21.85 mm
255: Acts like a: 22.18 mm

Hotchkis 1 in (24.4mmOD 17.4 ID): 342 lbs/in (Based on past information about Hotchkis bars, note their design may have changed)

19mm Bar: 137 lbs/in
1LE Bar: 205 lbs/in.

Now you know why people like Sam and myself and many other people who road race/autocross these cars don't run rear bars larger than 21 mm unless the PHR is lowered or a WATT's link is utilized. The diameter is raised to the 4th power, so in simple speak "It makes a BIG difference"

One other point. I don't buy springs unless I get the spring rates and the ID and wire size. I don't buy sway bars unless I get the OD, ID and effective arm length. If a vendor is not willing to provide that info, I purchase from someone else.

Cool, thanks for the info Major_Lee_Slow !



FYI, you really need to work on you people skills, just as much as I need to work on my math.
