I do about 15 track days per season. I always have my vacuum bleeder with me at the track just in case, but I have never needed it. I never needed to bleed the brakes, good pedal throughout the season. Never lost brakes either. The tracks I run are good for about 135mph. I run el-cheepo Hawks HP+.
Really? On your M3? That's suprising...you must be getting lucky because those pads typically are great to the point where they completely fall off a cliff. They're discouraged by many brake companies....I think even Hawk.
