To All: I certainly hope you guys don't mind me jumping in on these problems?
Rear lower control arms, it is VERY unlikely that the bushings are bad, look at them and see if they have major cracking in the rubber itself- rare, if not it is probably not the bushing causing the slop or noise on rocking the car back and forth or the slight slop that a good driver will feel in hard manuevers BUT a to small diameter lower mounting bolt! This will allow the entire lower control arm to rock against the bolt.
Easy to check, take the weight of the rear end by raising the "Frame" then support the rear end and remove the lower control arm bolt. My bet is the bolt will be tight going into the lower cotrol arm bracket but has slop in the bushing. Simply drill out the lower mounting bracket to the same size hole that is in the bushing, install new bolts for both sides: Problem solved.

Side note: Lower control arms are weak BUT only if you are pushing more than an honest 500 HP and really getting into the road race stuff. (Testing at Honda's test track-Marysville, Oh. by a profesional driver- we sarted out with skid pad testing and only got approximately a .78 skid factor using stock un-modified parts, by the time we got done we were getting 1.78 skid data- this is exceptional for any car let alone a replica! While doing the above bolt repair, look at your rear supplied lower control arms; you will see they look sort of like a railroad track with two parallel arms welded on each end with the bushing support, simply take a couple of 1/4" (+/-) plates, weld them across the tracks top and bottom and box them in. You can't get a better lower control arm anywhere. If any one wants this done and has trouble finding sopmeone with the tools by all means know let me know. You pay shipping both ways and I will be glad to do this for you for free. Only cost is if I have to have a friend cut us some steel. A previous person absconded with my plasma cutter so I can't cut them anymore.

Hope this is on target...and it helps
