Solid rod ended Lca or poly I'm finally about to lose the 10 bolt in favor of a real rear end. I was at the track not long ago and busted a pinion yoke, which I'm suspecting the stock Lca bushings may have been the root cause. I'm about to change them in favor of something stiffer, but in my research I haven't found the data I'm looking for. What I'm wanting to know is, are there any fast guys around here still using poly bushings instead of the solid ended control arms? I want the rear to be rigid of course, to keep from breaking more yokes.... but if I can help it, keep the ride somewhat liveable. Thanks.

Almost my entire rear suspension is comprised of Heim Joints and for a street car its not what I would recommend.
I can feel every little bump and crack in the road and as they wear they get a little play in them they clunk over sharp bumps. (expansion joints, pot holes etc.)
I called the guy at UMI because I thought there was problem but he said that's very normal and to be expected from a race suspension used on the street.
On the plus side the car goes straight as an arrow under power, there is zero wheel hop and in the corners its very solid.
I guess it just depends on what your willing to live.

I haven't had any issues with it and I beat on it every time I drive it.
People say that when you throw a sticky tire on and launch hard that it will start to howl, nothing fails or eats itself up, just howls.
When I got my car it howled on accel w/ 4.10's at 50 mph pretty badly but after I put in a used set of 3.73's and set it up correctly it barely makes any noise even with the solid mounted torque arm, I also haven't launched it with a race tire yet I might add.
I would do lots of research before deciding but I'd be leaning toward a 9" personally.
The 12 Bolt uses 3 and 4 series carriers so if you want to change gears sometimes you need to change the carrier, hence the reason I went 3.73 since I wasn't about to buy a new $700 Traclock lol.
I don't think you can go wrong with either the 9" or 12 Bolt really.
