Front wheels 16x6
Rear wheels 16x8
Bolt pattern 5x130mm
My dad had part of this set on the rear of his 914, but I'm putting that back to the originals, so no need for these anymore.
Based on some internet searches and the numbers stamped on these, they appear to be genuine Porsche wheels from around 1991.
The tires on them are 20 years old and should not be driven on, but they do hold air just fine (been kept indoors out of the sun in a climate controlled shop).
Wheels are in very good shape - a couple little scratches here and there. I did a quick but not thorough scrub on the backs, but the rest of whatever-that-is will scrub off. There are zero curb gouges.
