I was wondering how aftermarket lcas give better traction. I don't see how they would work but i hear they make a big difference. I know if you have adjustables you can adjust the length or whatever and change the angle so that could have some effect but what about non adjustables? Is it a strength issue and the tubular ones don't flex as much as the stamped ones do?

The stock arms have rubber bushings that allow movement under load; they're great for isolating noise and preventing binding around corners, but do allow the rear end to pivot somewhat under straight line acceleration. Aftermarket LCAs come wth poly and/or sperical joints that reduce the "play" associated with rubber bushings. The stock arms are also U-shaped, allowing some flex of the metal arm itself. Aftermarket arms are either tubular or a square channel that won't flex under load.

Yup, as he stated it.
Less flex in the shaft itself due to being tubular or rectangular tubing instead of a pience of stanped sheetmetal.
And less flex in the joints to due Poly bushings (less flex), or Heim Joints (No flex).

Hmm im kind of interested in getting a set for my car. Is there much point in getting some for an all street car? They aren't too expensive and im sure the ones on my car are getting worn out. Also should i get adjustable or just regular?

for strictly a street car there is no need for adjustable ones.
but you will benefit from them. the rear will be alot more solid under spirited driving. you'll probably notice less wheel hop during launches.
BMR makes a poly/rubber bushing combo on thier lcas...this gives you the best of both worlds. the rubber is still stiffer than stock (even new stock) yet gives a little bit to prevent bind and noise. not saying poly/poly bushings are noisy, but they can transfer more road noise into the car...it's just the nature of the beast.

I have never got any noise from my old Poly/Poly set up

oh i agree completely....but realize some people are more conscious of minor road noise.
so the poly/rubber is a nice option.

aLright ill look into them thanks for the info guys i may get a set soon. Im used to road noise. My last car had an exhaust leak that i didnt feel like fixing and this one has a cutout thats always open. Once you get used to the tone, thats al lyou hear. So poly would be fine but I am a fan of bmr.
