I'm very happy so far with my Spec 2. The pedal feel is very close to the oem clutch in my 09 Spec B. I would think any stage 2 type clutch would be good for the masses.
Both Mike's (m sprank and AZPinstalls.com) are better ones to ask about that. Mike from AZP does auto-X from time to time. m sprank has been working on these cars for a long time.
