    Yep, go the 12" route...larger diammeter pressure plate=more surface area=more holding power at a given pressure plate clamping force...

    Go with the 12".

    I've heard the smaller the diameter, the better they are for drag race applications.

    Got the 12" ... strange that the main difference was that the 12" has three prong style where as the 11" had the diaphram style. Oh well it will be much easier sliding in my big phat sm465 without as much concern for the diaphram splines. Overall this thing looks heavy duty!! Can't wait to see if it can actually plant most of the 330 horses my engine kicks out. This will be after an extensive grandma driving style while breaking it in. No use in throwing a brand new clutch down the drain...
