My clutch was slipping on v6 Sti, so change with new excedy kit and it's still slipping not as bad but still slipping on boost.
Is there any other reasons why it would still slip, other than worn fly wheel?

 

What power are you running, which clutch kit exactly are you using and where from?

Did you notice any oil contamination on the clutch when you took the old one off?

 

Answers above

 

Does any body know if there is any adjustment on either clutch pedal or master cylinder?

 

Right have checked slave... There's no problem there.
Have removed and refited fork all lined up with bearing. So no problem there either.
Visually there was no wear on flywheel.
So everything seems to be pointing to a flauty pressure
plate.
Has any one had any problems with exedy kits?

 

Did u resolve this??? Ive fitted excedy blue today with no oil contamination but still slipping!!!! Standard boost wrx classic??? Arghhhh!!

 

Yes bud, take it to a steep hill try a hill start. I had snapped my drive shaft in the cv boot. So was being held by the cv boot and not banging about. Only found it on hill start as it was spinning and banging on the hill.
Good luck with it.

 

Glad u sorted it mate,ive had all my driveshafts out today well the back two coz ive converted it to rear wheel drive and there fine,anyone got any other ideas????

 

I would still take the boot of to check as mine all look and felt ok. Untill I took to boot of.

 

U did replace your flywheel or at least re skim

 

Is your front diff welded then?

 

Yess re-skimmed fly wheel mate,ive welded my centre diff

 

That's properly were the problem is as the power will be taking the easiest route through the diff. Causing similar symptoms to clutch slip.

 

Do i need to weld/remove the front diff then mate?

 

I wouldn't bother as it will never be able to hold for any length of time. The best way would be to fit a rear wheel drive box from say something like skyline. Then fit a conversion ring for bell housing. Rear running gear would also need modding. Or just fit a a type r dccd box and running gear.

 

All sorted now it was the slave cylinder holding the clutch off a little
