This is a 1978 911sc with steel 930 fenders.
It had been built to look like a 964 with cup 1 wheels and these 993 calipers.
Front rotors are 32mm thick x @ 335 mm diam.
Rear rotors are 28mm thick x @ 300mm diam.
Maybe 993 rotors but I thought hats had to be changed out etc to upgrade rotors etc.
I like them and the way the perform but want to know what I have.
Also want to get wheels and need to know what this may have done to my stock hubs to assist with offsets etc.
Any input would be appreciated.
