After going though a number of King Cobras with their stiff feel, I switched to a Spec clutch and couldn't be happier. I also use the firewall adjuster along with a quadrant.
I tore up the first Spec because of something stupid I did and yet Spec stood behind it as well as resurfacing my flywheel. They were awesome.
