Identifying a Z51?
Hello,
I'm trying to determine whether my '90 is equipped with the Z51 option. The RPO sticker in the center console is partially torn off. I was able to identify several RPO codes that were still intact on the sticker. It has FX3 adj. suspension, KC4 which is the oil cooler, GT7 which I believe is the 3.33:1 rear axle, and then FE7 and J55 which someone told me is performance suspension and brakes. Would this indicate a Z51 optioned car? Is there some mechanical piece on the car that would indicate if it is? Thanks for the help.

Although I'm not sure if it's different on older models, on Z51 'Vettes the steering wheel should turn either 2-1/2 or 2-1/4 turns lock to lock. On a non-Z51 equipped car, this number will be a turn or so higher... I know the numbers are in the MidAmerica catalogue - I just don't feel like looking 'em up right now.

The build sheet on the top of the gas tank will have the RPO codes listed on it but it's difficult to remove.
You can buy a copy of the build sheet and the window sticker from the National Corvette Museum. Go to
https://www.corvettemuseum.com/libra...ts/index.shtml to get them.
