They are cross drilled and slotted....and they are coated in zinc. They are also made here in the US and are thicker than the crap you can find online. They are also made to order as well. Very happy with them and they have great reviews and recommendations online as well. I only drive my VX about 1000 miles a year. Also one rotor was shot and a caliper was shot. So my differences are amazing in ride, stopping and I guess looks. I wish I could find a nice set of CALIPER covers.
I am very happy.
