SPEC Stage 1.
I'll break it down for you.
Stock clutch was pretty much dead at my first tranny rebuild at 37k miles.
Replaced with a Grizzly OEM clutch. 2nd tranny rebuild at 52k miles while installing 3L. ~500 miles later, the clutch went out.
Replaced the clutch with a SPEC Stage 1. Have had it in for ~35k hard 3L miles, and it still grabs like the days it was first broken in. It feels stock with daily driving, but bites hard when quick shifting at high RPM's.
I wouldn't even mess with any other clutches. Stick with what is known to work best.
