Good question. About 2 years NA 30k miles, one year boosted 20k miles.

 

No, I'm leaving the flywheel alone.

Xtreme and Exedy both seem to review well. Check the torque specs Martin. Exedy stage 1 is rated at 190 lbft at flywheel, 160 at wheels supposedly. Your car produces more torque than that , I believe.

What are the telltale signs of a slipping clutch and how much is the replacement going to cost all in Martin?

I'll double-check with Scott at Abbey. Mine peaks at 282nm which pushes it for the Exedy Stage 1.
I've been quoted £750 all-in. Gearbox out, it's a 4 hour job.

I guess there's a balance between clutch feel and clamping force.

It's my daily driver so I don't want a heavy clutch. I'm also easy on my clutches, I never dump them, I try not to slip excessively and I don't track the car.

For reference, Tuning Developments use the Exedy Stage 1 kit in their Turbo Stage 2 package, which produces more torque than the 280nm you listed above. 

I know the power delivery will be different but I think Exedy understate their performance figures on their clutches.
