But I'm curious on the Boxster S owners with the stock crossdrilled rotors. How would those rotors be regularily maintained?

Hi,
Crossed-drilled rotors on a boxster are about 99.% asthetic, maybe 1% of them which are tracked regularly actually need them to off-gas the pads.
But, their strength
is compromised by the drillings, so they cannot be turned or machined because this would further compromise them. If the lathe didn't cause them to crack between the drillings (and this is why most machine shops will refuse the work), they would most likely crack shortly thereafter.
Unfortunately, if you wanna look cool, you got to pay the price...
