If you need to dial in your clutch engagement, this is the ticket! Most pressure plates are not optimized into the correct position and don't apply full force to the clutch disk. I have incorporate small locking tabs to prevent them from falling off your bolts during assembly, which I have struggled with in the past.

The first method is using an old input shaft with a socket welded to it. With your flywheel locked you can then check the breakaway with a 250ft/lb torque wrench. Start without shims and adjust the torque wrench to find the lowest breakaway. This may be 120ft/lbs. Then add shims and recheck until you max out, which might be 130ft/lbs or 150ft/lbs+ depending on disk, PP and flywheel.
The second ideal method is to watch Tom Simpsons video and make yourself a pressure plate dyno using your shop press. This is the most accurate and quickest way. Video link below!
