BMR Torque and LCA's
I'm thinking of buying a BMR Torque arm and their LCA. My car is NOT lowered and don't plan on doing so. Is there anything i need to be warned about? Any vibration issues? I read that "Not so good vibrations" thread under mine and i dont want that issue. i'm getting the NON-Adjustable ones. so with stock ride hight and 17"-18" rims, any worries? Or is it just with lowered cars u have to worry?

You should be fine. Although I would recommend paying the extra for the adjustable torque arm....

I have a non-adjustable BMR torque arm and it is nice and quiet, comes pre-set to -2 degrees also. I don't see it worth the extra cash and hassle for an adjustable if you aren't lowering your car or going for the extra .01 at the track. The way I looked at is am I willing to crawl under the car and adjust it at the track a bunch of times? The adjustability is nice but if you aren't going to use it then don't bother getting it.

Does the adjustable offer anything other than easy pinion angle changes?

My poly's have never bound up,most of the time that is because people tighten the hell out of the bolts holding them on. I would highly recommend if you do go Poly you buy a set with Grease fittings.

You should. I can distort stock LCAs just by twisting them by hand.
I think the BMR LCAs come with the fittings. Buy a tube of the grease as well, you should service them at every oil change.

Is that a 4th gen thing? Do their LCAs suck a lot?

Stamped steel, non boxed channel-style. I had the same ones on my GTP, they make up the shoulders on my "muffler man". They aren't the greatest because they deflect under hard cornering. Upgrading to tubular or boxed can be a pretty substantial mod. Even boxing them with a $4 piece of sheet steel can make a difference.

The "bind" has nothing to do with how tight the bolts are. They bind when the body starts to roll in a corner, causing the front axis (bolt) of the LCA to no longer be parallel with the rear axis (bolt). The stock rubber bushings have a hollow at the top and the bottom, to prevent that from happening.... the bushing allows the front bolt to rotate relative to the rear bolt. Solid/hard poly bushings will screw up the handling if you want the ultimate cornering capabilities. For straight-line traction, bind is not an issue.
The options for preventing the bind are spherical rod ends on both ends (noisy/harsh), poly on the body end/spherical rod end on the axle end (reduces noise, keeps it away from the body), or rubber body end/poly axle end (no noise/not harsh).

when i had all rod ends in my 91 RS it wasn't bad to ride around in at all. the travel is so much smoother than with bushings that the car actually rode better that it did with the eibach+bilstein combo than it did on the stock rubber stuff.
there is some noise, but it isn't anything that drowns out the radio or exhaust, so it wasn't ever a distraction to me.
