Rear coilovers, torsion bar reindexing and rear ride heigth.

Dan thanks for the clarification.
How do you like the 450/525 spring rates?
I'm currently thinking softer springs than you, maybe 275 to 350 in the front and 450 to 550 at the rear, but am planning to go with polybronze and other hard mounts right away.
Dimi, as I understand, it's the spring plates and bushings and not the control arms that are the weak link in the rear suspension. I don't think 500-550# springs are an issue but any upgrade to the rear suspension requires attention to the bushings and mounts.

Just get the escort cups they are perfect and RUN your t-bars. The Turbo Cup cars ran this set up as well. So if it worked from them it can certainly work for anyone IMHO

Problem is the escort cup coilovers have rubber bushings, there are better alternatives out there these days.

I'm not sure if you are confused or I am, but the spherical bearings and mounts we where discussing above are not the upper and lower mounts built into the shocks/coilovers.
Not saying what you are doing is not possible, just not sure what you are doing. If you press out the rubber bushings on the upper and/or lower mounts of a shock/coilover what are you replacing them with (spherical bearings?), how will you hold the bearing in place?

Please post more details on this. I would think it was a more complicated procedure than simply pressing out the rubber and fitting spherical bearings. If you use c-clips to hold the bearing in place you would have to have the carriers machined with a groove on both sides to accomplish this - a difficult task on a coil-over, plus I don't think the carriers were designed for this, you would be weakening the mounts. That is, if you found a bearing that fitted exactly into the carrier housing and could handle the loads in the first place. Don't forget that some of these track cars are using 1000lb + rears spring rates.

So I spoke to Bilstein and they said that they convert the shocks for $150 a peice and they install a spherical bearing on the place of the original rubber mounting bushing.
