Get the stage 1 cluch.

It will hold even the turbo 3L's torque, at least in the 300-350 HP range and it will be the most streetable. Smooth engagement, lots of grip.

I have the stage 3 and it is a 4 puck clutch. I don't have much chatter now that it is broke in. It is still very streetable, but it has some serious grip! Neck snapping grip if you let it out fast.
In fact, the hotter it gets the more grippy it becomes. As someone said, it is very smooth when the clutch is cold; it feels like a normal sporty clutch until it warms up a bit.
