Excuse my French but i'm lekker gatvol.
I eventually fitted my over priced copper clutch , now its slipping worse then a standard one. Did i do something wrong or is there a trick to it? Should i run it in first?

Clamping force of the pressure plate should be correct.
Was the pressure plate/flywheel skimmed?

And as with any clutch you should run it in, drive like a civilised person for about 500km and it shuold be ready to go.

Did you re-use your old pressure plate? Did they check that it had the required clamping force?

Also the actual thickness of the clutch should be compared to the old one to make sure the flywheel/clutch plate/pressure plate are at the correct offsets.

But if it's slipping under power it's proably a clamping force problem - that's why the copper clutch I took out was originally slipping. Had it fixed and no more slipping...

How and by whom?

Copper clutch will slip for up to 700km, leave it be and it will come right.

Roadrunner. They relocate the pins holding the pressure plate. The old tabs that the original had on couldn't provide enough force.

Can't remember how much it cost, did it with the whole clutch rebuild.

check the fingers of the pressureplate, when bolted down they should point outwards, what I've seen before is that the copper clutches are way thicker than a stock one, then when the pressure plate is bolted down it pulls the diafram of the pressure plate inwards, loosing clamping force.

The fingers are more or less neutral. I measured the plate thickness and its like ,2mm thicker then the newish std one i took out.

0.2mm isn't too bad, just drive it easy for the first few km's, sould be fine afterwards, if the pressure plate have enough force.

my clutch never slipped, worked fine from day one....then again, I had a double diafram pressure plate.....
