As an extension to the discussion on track brake fluid, I'd also like to understand experiences with track pads. My experience: Stock: useless at the track. Porterfield R4S: down to backing plates after one weekend at Road America. Carbotech 1108 (race pad). Good performance. Better wear characteristics. Carbotech 1109XP (current - race pad). No fade, higher initial bite. Good pad life. Not too hot on a cool or wet day with occasional use The BMW guys seem to swear by Hawk pads. Certainly the M3 lightweight I rode in around RA (2:35 laps) braked extraordinary well. I'm tempted to try the Hawk pads next season. Experiences?
