This is the new rotor and the stock unit. Stock rotors are 18mm thick new, and corrado is 22mm. So i machined of 2mm at each side. Take care when doing this and dial it in carefully before start cutting, otherwise the brakes will pulsate as hell. I also drilled gas holes in the new discs, and a friend of mine phosphated them so they wont rust. The phosphate will come of the friction area.
