Base vs. S brake measurements

[dav9515]

Jeff, thanks i saw there was a kit from brembo however the rotors are Porsche parts and stamped with Porsche part numbers. i was under the impression the Brembo kit would have used brembo rotors, was that not the case? did they actually take Porsche rotors and machine those to fit? if so it would make sense why the kit was so expensive

if it is the Brembo kit, am i to understand when these rotors are shot i am kind of screwed as they are no longer made? or is it as simple as unbolt the caliper, remove the spacers, put on stock base size rear rotors, rebolt the calipers without spacers and good to go? from what i read, the brembo kit was made not just to upgrade the rotor but to accept the S caliper as well. If that is the case and the rotors are no longer available i would need to switch back to base calipers to accept base rotors as well?

translation - a rear brake job is going to cost me a fortune if i need new rotors lol!
