Guys
PLEASE EMAIL ME so I can collect details.
Also I after some guys at the NECO forum didn't believe my claims on the stiffness and weight savings on the 24mm hollow bar, I posted this meassage:
OK, seeing as none of you believe me I will give you the engineering math. A hollow bar of x mm in diameter is not necessarily torsionally stiffer than the same bar in solid, BUT the difference is minimal , yet the weight reduction is signifigant.
Any how, the Polar moment of inertia
J is directly proportional to the the 4th power of the diameter, and as such the equation for polar moment of inertia of a solid round bar is:
J=(pi*d^4)/32The same equation for a hollow round bar is:
J={pi*(do^4-di^4)}/32, where do is the outer diameter and di is the inner diameter.
And due to the fact that we use such a high power (4) the removal of the center doesn't really hurt the torsional rigidity, but save a LOT of weight.
Hence for a 18mm SVT rear sway bar the polr moment of inertia is 10305.994mm^4
For the aftermerket 22mm solid it's 22998.029mm^4 (223% stiffer than stock)
And for my 24mm hollow (15% wall) it's 24751.487mm^4 (240% stiffer than stock and 17% stiffer thanthe 22mm bar)
But here are the weights!
Lets compare cross sectional areas; the 18mm bar is 254mm^2, the 22mm bar is 380mm^2 and finally the hollow 24mm bar is 230mm^2. So if all were from the same material the 22mm bar is 50%
heavier than the stock SVT bar (18mm) and the 24mm hollow bar is 10%
lighter than the stock SVT bar.
So you CAN have you cake and eat it too.
Now.... I don't want to hear anymore BS please, just orders!
email me if you want to order a bar at sarigia@aam.com
Thanks,

Also, from what I understand, the rear sway bar is the same on ALL Contours from '95 to '00./ So it'll work on any Contique or Cougar.
