I bought these 9" X 15" Fuchs wheels in Germany late 70's to mid 80's.
I ran them on my 911 for 4 or 5 years before switching ti BBS wheels.

I was told the Fuchs modified these original wheels to fit over larger front race brake rotors and calipers for the 911 RSR race cars. They called it







Flat Bed Modification.
The welding has been done very professionally with perfect balance.

Anyone know any more about these.

 

early 70s RSR race cars used what are essentially 903 brakes which fit in any7, 8, 9, or 11" Fuchs, stock on a '73 RSR was 9ET3 and 11ET-27

I'd be wary of using those wheels, no safety humps

 

A few of the guys i race with had some 15 inch Fuchs welded up and turned into 9 inch wheels so they can run Hoosier 275/35/15 rear tires, pretty common before
PCA maxed the tires to 245/40/15.Basically everyone now runs 8 inch wheels ...

Cheers
