Long story short. Changing out the 5 speed Boxster, for the 6 speed Boxster S.

I got the adapter plate from Kitcarchassis.com.

He recommended the Spec Clutch. SP902S.

Anyway, now that my new mechanic is starting in, there is some question as to the clutch being borderline heavy enough, or should be bumped up a bit.

The person I got if from says they are usually run a bit more than what they are rated for, and is a light car, and not using it for racing.

The clutch I have is rated for 485 ft/lbs of torque, and engine 473 ft/lbs of torque.

Not sure if I should keep the stage 2 or go with the stage 2+

Do both clutches work with the same adapter plate?

If so it wouldn't be the end of the world to change out later if disappointed.

Yes.
What I ended up doing was sending back the disk I had, and upgraded for the 2+. Rated for 545 ft/lbs.
It's a spec clutch.
