Hi s3_trev and AndyParker,
As Alex says, the Spec Stage 3+ clutch I'm getting can be found here:

Basically, my simple reasoning is this - if it's good enough for Alex's beast of a car, then it will certainly be good enough for mine!!
The Spec clutches are imported from America, so there may be tax duties and delivery charges to consider on top of any prices given - including the cost of actual fitting of course. I dropped my car off at AmD Essex this morning, so I'll let you know how much it all comes to when I pick it up on Saturday.
I also went straight from standard to Revo 2+ (just over 2 years ago now), and the stock clutch was absolutely fine for around 10k miles before it started to slip with 'spirited' driving.
I'm actually quite a leisurely driver most of the time, and don't tend to drag race from a standstill too much, which could be the reason why the OEM clutch lasted for so long.
I think the standard clutches pretty much vary on a vehicle-to-vehicle basis, so until you get the remap it's almost impossible to gauge how your clutch will react to the extra power and torque.
I know some have had their clutches slipping on them on the way back from getting a remap, some may last a week or a few months, and some (like me) seem to get away with an extended period of time before the clutch begins to slip.
So the one thing I would probably say is to bear in mind that you will need to factor in the cost for an uprated clutch if you're thinking of going to Stage 2+, but you may not necessarily need one straight away...
