Are you talking about an act clutch? If so they do make a extreme pressure plate for the 240mm clutch. its N013x where the hd one is N013.
So why hasnt anybody noted that from a stock standpoint that the 240mm flywheel and the 225mm flywheel are the exact same size? Its just where the "cooling ring" is machined into it and where the pp bolts are drilled. I guess you could even say the 240mm flywheel has less inertia because it has 3 extra bolt holes drilled in it lol
