The McLeod Street Pro 75109 I have is a Diaphragm. Summit shows the Super Street as a Diaphragm as well. They likely use the same pressure plate as the clutch discs have different media. I will be adjusting mine today or tomorrow and will post feedback. Mine likes to shift hard and the clutch pedal doesn't return because my dad believes in the 1" slop rule.
My truck did the same thing (dad adjusted it...) until I ran the bearing up to touch the pressure plate then backed it off by feel of the pedal. Works great now.
