I have a complete set of NOS NIB OEM (Zimmermann) front disc brakes for the 1970-1972.5 & the 1972.5-1976 that I dug out. Yes, they are still sealed in the box!
I really don't plan on using either of the sets although I may keep the 72.5 & later for a little while longer.
Genuine Porsche (zimmermann) front brake discs are NLA and it appears Sebro is one of the few alternatives.
What could I realistically get for the 1970-1972.5 front brake disc set & the 1972.5-1976 set? Part numbers are #477.407.075 and #477.407.075B respectively.
