18zl/zr 6 piston Cayenne calipers to a 930
 

Has anyone used these brakes calipers ? if so where can one get the adapters to mount said brake calipers ? I'll be running 18 inch wheels as well and yes bigger rotors

anyone?

Do you still have your 930 calipers/rotors? If so, what are you looking to improve on, as they're considered the "gold standard" w/r/t fade resistance, etc. for our air-cooled cars.

Sell me your 930 calipers. :-) Don't believe I've heard of that conversion, though it's probably possible with enough fiddling. I think there are other easier known conversions that will still give you a bigger caliper for looks if that is what you are after.
