Couple of points of reference. One is anecdotal, the other experiential. The anecdotal piece is based on information I received about 5 years ago. Back then, I was told (by a reputable source) that the Edelbrock IAS struts / shocks were simply Bilstein models with white / red paint instead of yellow / blue. If that's still true (back then you could tell by looking at the piston (diameter) and production markings stamped in the body), they are going to be awesome for your car. I don't know that's still the case, so do your homework.
The springs are the pieces I actually installed on my '93 convertible. They were really nice, quality pieces. At the time (2001) they were stiff, but not uncomfortable. They made a huge difference, and based on that experience, I'd be comfortable recommending them. Good luck and let us know what you find out about the struts / shocks. I'd be curious to know if these are re-branded Bilsteins.
