Check out Gordon N's CMC Calif - you can't beat the look of Fuchs alloy wheels and replicas are reasonable (OEM not so unless you get lucky). You have the original CMC optional wheels - which now 30 years later look a little dated. You need to consider off-set/backspacing along with rim size/with and tire size/profile. I think Gordon's look just right (believe they are OEM Fuch$). You can always add spacers to push wheels out a bit - but will need longer bolts/studs. Of course, for the 5 bolt Porsche pattern wheels, you'll need new/redrilled rotors and drums.
