I put the ebay coil overs on all 4 corners, I got a sbc (archie kit) in the back and the rear dont feel to bad. I rebuilt everything on the front, new bushings, upper lower ball joints, rebuilt rack, everything I could do and the front feels too tight. After 2000 miles on it now its softer but good enough.
Im in the process of buying a new home right now, my new house has a 1800sqft shop so I have big plans for my Diablo once I get settled. Im going to look at putting in a aftermaket front K-member in it and redo the entire suspension. As well as finishing my twin turbo LS1/ TH425 reverse rotation drivetrain....
