DBA has designed a track ready two piece rotor for the oe (2 pot) calipers, designated the 5010. It utilizes the same kangaroo design technology as their other rotors ( a series of different shaped pillers/columns that help pull hot air out of the rotor- also stiffen the rotor). It also manages to squeeze an additional mm in width and diameter. By my scale, about a 1 lb weight saving over oe- talking to Steve weight wasn't a concern- cooling/longevity were. Combine this with a worthy pad (running Enless CCX now, but switching to Ferodo DS2500's soon), ss lines and uprated fluid and you'll have brakes that will work on the track or getting the groceries.
Flash made the tops look a little different color than they are.
