Calm down man, geez...
I know a lot of guys run Moog rear springs and are happy with them.
For more info than I care to type, look here:

About 2/3 down the March message list, you'll see messages concerning "Rear IROC springs". Read those and you'll get a TON of info, suggestions, and hands on experience. I also recommend subscribing to the mailing list. It will add to your inbox but well worth it for the info all these guys provide.
How's that???
