I would suggest that you research it before you buy. Your Caddy has 115mm offsets and that may make your selection more diffucult. I'm not familiar with the fittipaldi wheels, so I'll let someone else chime in on that brand. Cadillac wheels are of excellant quality, and you might find a different set than what you have for good price on Ebay. Good Luck either way!
By the way, Welcome to the CadillacForums! What part of Tennessee are you from?
Welcome.... I think you will be able to find what your looking for in another cadillac wheel.
The thing is, most other wheels arent built with the same quality as the cadillac wheels are, and are mostly designed for compact cars, and therefore may not last AS long on a heavier cadillac. Cadillac offered many wheels, and they are all interchangable...
I have been looking into replacing the stock rims on my 94 FWB. Is there some place that carries Cadillac factory rims online? I've never seen them listed anywhere, and it would be nice to see all the sizes/designs in one place.
