I have the coated and cross-drilled Zimmermans on my S70 and have 50,000 miles on em. They were great for the first two years, but heavy stop and go driving has warped them a bit. Still, they lasted longer than stock Volvo rotors did. Mine were made in Germany; circa 2010.

A learning experience is one of those things that says, "You know that thing you just did? Don't do that."
