there are camber kits on ebay right now.....
buy a cheap 95-01 i think FRONT DODGE NEON STRUT TOWER BAR off ebay for like 25 bucks with shiping, put that on the REAR of your SHO. CHEAP, EFFECTIVE
ALuminum Subframe Bushings are awesome for the money........
there are also some cheap Subframe connectors on Ebay right now but I don't have any personal experience with those, can't be bad though.
Polyeurethane HD rear endlinks are fairly cheap mod too...
bushings can be expensive and a PITA to install. I would do the above mods first if your on a budget, if your not on a budget find some Rear control arms and an H-brace, I just bought that setup and will be putting it on shortly and I can give you a report on how that works out. My complaint is my SLO has a real floaty rear suspension, could be those cheap *** suspension arms, could be my 90k stock struts with saggy springs....... I will find out soon LOL.
