As you've already found out, they are real Fuchs- you can even see the little 'Fox' logo (Fuchs in German means fox) in the 5th pic. The 911 part #'s tell you the wheels are off of a 911- I mention this because there are 7 and 8x16's with 951 #'s with ½" more backspacing, which are 944 wheels.
As already said, chroming your wheels will lessen their value a lot, as once done it's a lot of work to return them to their original anodized state. I've heard it said the chrome can't be stripped without ruining the wheel; you'd have to check with a wheel shop that specializes in this. If the chrome chips or starts to peel (which some say inevitably happens with chrome on aluminum wheels) it's really hard to repair. Stripping the anodizing and polishing lessens the value only slightly in comparison, as they can always be re-anodized.
@Jimmy V.- Whether you'll feel the extra 4 or 5 lbs per corner will probably be somewhat subjective; I don't think it really matters that much until you're pushing the car close to it's limits. You may be happy with the polished (or chromed) replicas or you may always know in the back of your mind each corner is just that little bit heavy- I don't know you well enough to guess!
You'll notice in the chart above that the 6" (15 and 16), 911 numbered 7x15, and 16 all have the same backspacing, with the 7's having the extra inch added to the outside of the wheel. The 6's will non flared Speedsters front and rear, while I have no idea how the 7's will do in front, but in the back will need either shorter (earlier) axles and tubes or 1" narrowed irs arms to have any chance to get under the fenders. I went a slightly different way, taking a pair of 6's to the local wheel specialist and widening them 1" to the inside, turning them into copies of the 7" 911R wheel (somewhat hard to find and guys want big bucks for them when you do!) listed above. These, mounted with 195's, have about 1/8" clearance to the trailing arm and just fit under the fenders of my older IM with a single (modified swingaxle) spring plate inside the irs mounting bracket and type 1 drums. To get the type 3 rear brakes (they add 5/8" track on each side) under the car as well I will need to narrow the trailing arms. And I ultimately want to put 205's on it- hmmm....
@MikelB- I don't think you're going to get the 8's under the rear unless you pie cut the fenders, dude! Have you tried putting the 7's with tires on the front? Please keep me in the loop- I want to know how you make out.
Here's the Rennlist link- https://members.rennlist.com/911pcars/WheelWts.html
It has the 951 7x16 listed (also an 11x15 listed that no one seems to know anything about). Note that some of the offset and backspacing #'s are wrong and the weights for the 16" Fuchs are goofy as well- they're only about a pound (or a little less) heavier than their 15" counterparts.
Hope this helps. Al
