Be interesting to know why the one was heavily braced, and yours wasn?t. Different packages, I would guess.

As you know the GS90 and another C4 Corvette are very different and it is likely that the GS90 got the works, I'm sure it did. As far as I can tell there were a few C4 ZR-1 that Dick played with and he had a suspension package for them that was quite expensive about 14K if my memory is correct, and it often is not. Somewhere is the recesses of the internet I found and article about 4 C4 ZR-1 all black that he did various things to prior to the GS90. For what its worth mine was too low for daily driving I had it raised back to almost stock height and in my that opinion improved the car.

The GS90 ZR is THE #1 body style I would love to own. I realize there are only a handful.

looking thru some of my old catalogs, i found a 1991 Guldstrand engineering preparation manual and parts catalog.

there were 3 stages of suspension packages for the c4.

there is no mention of the GS90 cars except for Grand Sport 80A #17 averaging .95 G to take 1st place sports car international skid pad test February 1991.

global west still stocks the delerin frt upper and lower bushings. I did the rear heimjoint setup on the 415 a number of years ago. I also purchased the adjustable heim joint dog legs for the rear and the antiquated brackets from DRM. That combined with the cbeam plates and the coil overs from DRM made the car very predictable under hard acceleration and in tight turns on "Active Handling Runs" in the hills along the Mississippi River. Looking for the heim kits for the rear on the 93 now.

Part Numbers 1059 and 1060 for the frt upper and lower a-arm bushings.
