yeah, my Z came with cross drilled and slotted rotors.

I don't think the kid I bought it from even knew they were on there.

They do squeal a little bit every now and then, but I have no idea what pads are on there. Probably Wearever silvers or something crappy like that.

redoing the brakes all the way around and replacing the cross drilled with just slotted, or even blanks is on the to do list shortly after getting the engine running right.
