Do I Have My Spring Codes Wrong?

[Erik]

I'm trying to find the spring code for the softer, 1992-1995 ZR-1 springs. A trusted advisor told me I need FHA and RHY, but poking around a bit has caused me to doubt that.
Can anyone clear this up for me?
Thanks

Finding used springs and verifying code may be difficult.
Also, later springs will raise the the car a bit. I suspect GM did this to counter air dam scrape due to increased dip.

Not the easiest thing to follow, but I think my codes are wrong.

Looks like I need:

Front - FSM
Rear - RHY

Some contradictions in those charts too!
Thanks for sharing that.

Can anyone confirm I got it right?

This should help regarding codes. Remember, the search function is your friend...

Note the remarks from Marc Haibeck.

Well damn.
That confuses things even more. It would appear then that all ZR-1s had the same front spring, but just a softer rear spring? That goes against what Hib wrote. Hmmmmm......

Neither is a guy I would lightly dismiss.

My 91 rode like a go cart. 94, may not be like Cadillac, but much softer. Also, 94 sits about 1/2? taller. I think rubber pucks on the tip of the front spring makes that difference. I?ll be sure to ask David Mclellen when I see him next time.

I have some incredible, twisty back roads in the area. However, a lot of them are more then a bit worse for wear. It limits the enjoyment to have her jumping around on those. So I'm thinking a little softer spring would make for a happier time.

I would talk to Mirrock Corvette, look for or wait for a 93, 94, 95 or 96 corvette that got totaled - ZR1 or standard. ZR1 would be preferred. This way, at least, front to rear would be reasonably matched.
However, you are still stuck with early shocks (softer). Ideally, shocks should be revalved to approximate later car FX3 (stiffer). Or, maybe, later car shocks and FX3 controller could be substitutes. Actuators are the same.
