im looking 4 sum input.after the clutch started slipping in my stage 3 sapphire,i didnt know which one to go 4.so i phoned matt lewis who i use alot and i asked him.he basicly told me that you dont need all these fancy deer clutches,just a LUK clutch kit and a wee skimm off the flywheel to get rid of the hi points.i was a bit warey of going 4 it but he asured me that they were rated up to 25psi a boost and sells loades of them.so thats what i did,got flywheel skimmd and put clutch in,and the cars slipping on boost not bad but is slipping top end of boost and in hi gears.iv double checked the clutch fork is fully releasing the presure plate and it is.i also checked that the new clutch plate was thicker than the old one,and it was. the only thing im thinking now is that the presure plate is mibi faulty? anyone any other adeas???
