I did some searching and still have questions. I'm disappointed with my stock size front disks with cross drilled rotors and Hawk HPS pads. I am interested in upsizing my rotors to 12's but have a couple question that I still have after reading the sticky's. As I understand It I can use my current calipers and pads on the new spindle/rotor assembly. Is this correct? I did read about D61 calipers/pads but this seemed optional or a later upgrade. Will the 1LE rotor and stock caliper setup fit inside of a stock steel 5 spoke 15x7?
