It's odd that the three main hotspots are equidistant and matching. The three on the flywheel are where bolts are fitted to the other side. Also there's a lot of play (not rotational) between the centre boss and main mass of the flywheel.

There are some other areas of heating but I would estimate they cover no more than 15% of the surface. My guess is these are all high spots and represent the total clamping area.. Might therefore explain the slipping which should not be that bad, even with a standard clutch cover.

Really pleased it's finally working.

It IS a good clutch,but there was clearly something seriously wrong with your one from the start.

Thanks Alex. I think you're right. Can't wait to drive it now. Unfortunately gave myself a hernia ten days ago and having an op tomorrow - then no driving for ten days!!!!! :Flush:

Funny you say this.

Because i had the same problem with the kit that i got from aps as well. And had the same issues as you have described, and you would be the 5th person now i have read with the same issue with the S3 Clutch

3 months of having it in, i cracked it and removed and went a LOBA Motorsports SMF kit and i am 10x happier. (running sachs organic clutch though).

That sounds very likely.

You'd need it checked for flatness to be sure,but what else could cause that.

Good luck for the op!
