puck designs are like that...no more slippage into gear. give it a bit of gas and let off the clutch, don't ease into it. it should hookup right away, with no "studder". That's why they aren't the best for the street.

I dunno to be honest.
The design of the puck clutch is focusing all the rotating weight, providing for better clamping.
But launching from a stop has to be altered. Typicaly on a standard oem clutch, you ease into 1st gear, slowly feathering off the clutch. This is hard to do on a pucked clutch, as once it grabs, it grabs. So you tend to "studder" the car since it wasn't a smooth transistion and not enough gas pedal was given.
You can quickly get used to it, but you have to get used to it.
FWIW, the first time I drove a pucked clutch it was odd, but I trust I would have been fine after 30mins. Currently I have a clutch with an OEM surface on the pressure plate for semi-smoother engagement and pucked on the flywheel side for better clamping force.

well, i can start talking about the different characteristics of the friction materials, coupled with different clamping forces and the effect of having "pucks" cut into the friction material. and how that's going to change the engagement of the clutch, and its potential torque holding capacity. not to mention all the clearances involved with stepping flywheels and building custom clutches. but then again, a clutch isnt all that complicated, plus i prefer to keep it simple myself. or we can start talking about how a static compression becomes dynamic as a result of increasing cylinder pressure, and what the final compression ratio would be. that's a fun one, but you need to know some other things first.
