When I tighten the flywheel down, it does not spin freely, it feels as if the flywheel is contacting or rubbing the crank case. When I loosen it ,it feels okay. My vspec uses the same flywheel combo and does not suffer from this, I can move the piston easily up and down with my finger(not past the pinch)on the vspec but not on the P5. I tryed both the cone that came with engine and the one that came with the kit, both are doing the same. Did I over tighten? aren't I supposed to tighten it down? what do I do?

Try using a shim behind the collet.

Alright I'll try that, Thanks.

Any easy way to remove the collet?

Flat head screwdriver? Try to get behind it and wegde it off.
