safely narrowing a set of wheels?

From what size to what size?? Alloy or Steel??

I would hope to narrow a set of 19"s from 10" wide to 8"wide. These would be the rears. I believe the fronts may be available in 8" wide as is. My sense is that they are alloy wheels... probably made by BBS for Porsche. The wheels are the Carerra S wheel. A very ambitious wheel to try to tuck under the fenders of my Ghia. Not to mention the fact that cutting a wheel apart and putting it back together is probably not advisable. I'm no engineer but I have a little common sense that struggles with my affection for the look of that wheel.

Thanks,
