I'm in the same boat, pulled the Shelby Z out of the garage for it's first drive today, reminded me I badly need new struts/shocks, went to go look for a good-handling replacement (want to do casual autocrossing with the car - stock shelbyZ springs and swaybars); but Bilstien and Koni discontinued on us! Sucks. I can get KYB GR-2s no problem at work but I've put lots of them on cars but never have been impressed with them.
What I might end up doing is putting KYB Gas-a-justs on the back and getting the Monroe Sensatracs for the front. I don't really know any more than anyone else on this, other than I hear the monroes have a good warranty (may look into that tomorrow). Also Sensatracs work best at stock ride height - they have soft valving right at stock height for decent ride but the valving hardens up as it travels out of that zone. So that might actually work out good for me. Strange things happen with sensatracs with cars that have been lowered/raised, however, so be aware...

PS: That makes FOUR cars in the family that need shocks/struts, ugh! ('91 Safari, '90 Mark VII, '99 Grand Vitara, and the '88 Shelby Z)...
