Suspension

Just got a 94' cavalier and looking to change the stock Suspension
to performance Suspension. I was looking at ebay for some,
but it's for 95 and on. My question is it possible to put them on my
94' cavalier?

If it says that it doesnt include your year, dont buy the part. If the part would work on a 94, the seller would have included that year in his description. You can probably find performance suspension somewhere for it, check the Little Black J-Body book.

94 suspension and 95 suspension NOT interchangeable.

Two very different cars...
