I puchased a 1995 convertible with 20,000 miles, and the stock Bilsteins drove me crazy: harsh ride and lots of wheel hop on rough roads — the only kind we seem to have in Ohio. I went with the Edelbrock IAS Performers and am very happy with them. I bought them at Jegs, which is a local dealer for me, and the installation is very easy. The ride is much more civilized and I don't think performance was hurt; in fact, on rough roads it is better. Remember, the Edelbrocks were developed for performance under adverse conditions. Check out Edelbrock's Web site for a full explanation. I'm not certain that I buy all of the techno jargon on Edelbrock's Web site, but the shocks do perform, and, for me at least, they are well worth the money. (You also can unload the old Bilsteins on a Corvette forum site, which is nice for something that was going in the trash.)
