It hits like a hammer, if you don't like that or you run on a slippery track just skip it and go with the 2d because you would have to change the spring anyway. If you have traction, nothing else accelerates quite like it.
I run it everywhere with a 0.5 gap, and on a slippery track I go down to 0.3 which helps a little but the spring is just a beast.
IDM is coming out with a clutch based on the Sirio, but the story is that you get various clutch shoes and some springs for tuning but for $$$. I don't feel that the sirio clutch has enough time to slip because it hits so hard that the clutch shoe doesn't matter to me.
