I just bought a set of '86 951 Fuchs as track wheels for my car. They are WWWWAAAYYYY lighter than my C2 replicas. They don't look as good, but they look nice, IMHO (my girlfriend says they make the car look "dated").
I picked mine up, in mint shape, from a fellow Rennlister for $400 plus shipping. Put out a parts wanted ad, I had 4 or 5 people reply in no time, all with good deals...
