    Your 3.5. My 3.36 does 75 at 3000 (although my wheel circumference is a little lower than stock)

    To add my 'two - penneth'.

    I had a standard (but 240mm) flywheel lightened by 4 lbs (which was the extra weight of the 240mm clutch over a 225 mm one). Never had a problem over at least 10 years of 7k revving.

    Used a 'Centreforce 2' clutch, again it worked well. A standard 240mm clutch couldn't take the power of my modified engine.

    As a reminder - if you go from 225mm to 240mm you will need a different (longer) clutch release bearing collar.

    I have an ACT clutch which is very nice. "Light to moderate pedal effort" is a fat lie though.
    I have a mildly lightened stock flywheel - it hasn't exploded yet.

    I don't think there's anything wrong with lightening a stock flywheel, there's so much meat on them as standard.

    Yep - I work in km/h, so 70mph ish - 3000rpm.

    Effectively 4600 at 110mp/h although 80mp/h is the legal:rolleyes: limit here ;) !

    Nothing wrong, just not a lot gained for the money. My car back in 1990 has a stock flywhel with 25% 'shaved' off - was fine.
