It's time to purchase new rear rotors for my 67' S. I am told these are NLA, but my mechanic suggested cutting some 944 rotors. Sounds like a good idea, but is this the only option out there?

Also looking at new tires and there are too many too choose from. I currently have Dunlap H rated, 205/60/15s on the original 67'S Fuchs. Anybody have any suggestions as to what the best size and brand tires would be?

Thanks,
Josh
