AutoXSHO:
Be careful about these "group buy" posts. Apparently starting group buys on the forum has been deemed illegal by big brother.
I have replaced every suspension bushing on my SHO. It's not too bad to buy them individually.
The rear strut rod bushings can be purchased from Energy suspension (Polyurethane) and they work and fit great.
The front control arms should be replaced. The bushings would be a PITA To get on and off, though I have heard that upgraded units do exist.
The swaybar bushings can be had in TPR (the best material IMHO) from SHO-nut. Then do the subframe bushings and front strut rod bushings and you're done. (Except for the rear control arms, which I'm not aware of any replacements for. They dont' seem to wear out, however.
