    Cross drilled rotors are for posers. Get slotted. Cross drilled rotors will cause the pads to wear out more quickly, are more likely to crack, and don't offer the benefits of slotted. So, the only reason to get cross drilled is for the look. It's like a stanced car with crazy camber.

    Agree with all this and wanted to add the j-hook to the mix. AP makes legit kit. I'm waiting on DBA to come out with a 2-piece 5000 series personally..

    Agreed! AP makes a nice kit but it is a KIT. They will not sell you the rotors alone. You need to buy their calipers also.

    I don't know any racers who still use drilled rotors any more. Slotted is the way to go.

    NO. Their rotors are a smaller diameter and thicker when compared to the RS rotors so it is not plug and play with the our brembo calipers. Regardless, AP only sell theirs as a kit.

    Just wait girodics
