Hi All,
Wheels and offsets have always been black magic to me. I have a set of factory Fuchs wheels from my 3.2L Carrera. Can those mount directly on my 993 WB without issue?
Thanks in advance for advising this n00b.

Thanks, all.
The real end goal here was to put a set of snow tires on the 993. I happen to have new-ish snow tires mounted to the old Fuchs, so I was hoping that would work. So much for that!

16" Fuchs are finicky in terms of brake clearance. I don't think they'd even fit over 928 S4 brakes, let alone your 993's much bigger calipers.
Disregarding brake caliper clearance: Generally speaking, wheels from a G-model or earlier 911 (or early 944) won't fit later Porsches (all 928, late 944, 968, 911 series after 964, boxster-cayman etc. etc.). The offset was changed to allow the addition of ABS-ready hubs.
Offset diagram to help your understanding:

Some (rough) measurements that can be understood with the help of the above diagram:
G-model 911s run roughly 16-23mm positive offset.
964 (and later) 911s run roughly 52-60mm positive offset.
^Both those measurements are kind of average. There are extreme cases that are outside those brackets of course, such as WB cars and early narrow 911s, etc.
