Hello
I want to replace the rotors on my 914. I currently have vented 911 rotors front and rear. I am not sure if they are from an 83 or 84 911 sc.
Does anyone know the specs. to determine this.
I wish I had pictures to help.
Thanks
David

Of the top of my head...
Front SC rotors (78-83) are 20mm thick
Front Carrera rotors (84-89) are same diameter but 24mm thick

isn't there a difference in the rear, too?

David, I can't answer your question, but if you post a few more times, you won't be member #29 and still be a newbie!

I dont get enough time at home on the computer. Work keep me traveling. When I am home wife keeps me working!

The rotors should have part # etched/imprinted with minimum thickness ratings as well, on the sides....
