    * 1988-97 Oldsmobile Cutlass Supreme


You can locate your suspension type look at your SPID label (Either on the spare tire cover, driver's side door, or trunklid) Your Suspension Type is the 3-digit code starting with "FE". It's probably going to be either FE1 or FE3. I would tell you how to get your exact spring codes, but It gets complicated.

You could get lucky and have the original sticker still be stuck to the spring.  When I had my 96 Lumina, if you looked up inside the wheel well, you could see the "FUX" sticker still affixed to the spring.

I said "FUX this!" when I saw that...

Anyone know the spring rates of the front springs in the chart above?
My 1992 Z-34 with FE3 suspension still has the original "BPY" code stickers on both front springs.
