I would always use either a std Ferodo or Mintex pads. The greens are nasty, and tend to depsoit crap on the disc. I tracked a car on std road pads but cossie discs at donno and never had any problems. Ur always going to get sqeal with the fast road pads, and they don't bite as well cold. It takes 15 mins to swap pads, so get urself some race pads for track days if ur worried.
