Nice. Blowing through 75% pads in one day. That must have been fun. I'm currently looking for an older M3 to take to the track. A little more nimble than the 6, plus when I break it I still have the daily driver.
Do you have a manual tranny? I could not find much in TIS about the clutch for my auto. I'm assuming it's like any other auto tranny and uses the internal fluid.
