Hmmm, clutch has always been heavy but never slips - pedal travel is very short, like on or off, just had cambelt/water pump etc. done so loathe to sell now! Thanks for info, DR.If your clutch feels heavy, or is affected by getting warm in town traffic( poss slippage) then that's normally a symptom of the dfm failing, if you intend to keep the car then I would replace the dfm as you have spent the labour getting to that point. It seems there are wild variations on what type of mileages on how these things last. My dfm slipped when hot from 29000 miles, got gradually heavy
It lasted me till 125000 miles.hope this helps
Lots of ways the clutch can fail before slipping, lots of ways it can go heavy...Begs the question ... why are you changing a clutch at only 55K miles when it doesn't slip ? If it's because it's stiff/heavy then this is usually related to the release mechanism rather than the clutch itself. I had the on/off pedal effect but this was cured by simply lubricating the release arm bushes.
