the total surface area of the clutch pucks looks identical to the M3 design, doesnt look like an upgrade in terms of holding power, but it might be easier to slip.
if you want street, get an M5 organic clutch.
too bad they dont make some sort of wet clutch (not shared with the motor oil) that acts as a torque converter when the clutch pedal is halfway down, that would be fricken sweet.
