I thought in your initial post you got Brown's Engineering to do the work for you? What went wrong with that?
Personally after the terrible customer service offered by CG on their 666 clutches, I wouldn't trust them as far as I could throw them. There must be a way of holding the PP face solid without having to disassemble it.
Yes they did it but it was not true. They had great difficulty mounting it in their lathe.
When fitted it had worse vibration than with knackered DMF and also bad clutch judder, though the action and bite point were good with no slipping. But the juddering got worse and the vibration was driving me nuts. It also trashed the DMF in 8 months.
I spent ages going to different machine shops, drop it off, "Yes we can do it" only to get a phone call later that they couldn't.
It's like couldn't they tell me that in the first place instead of driving all over the place just to pick up another failed attempt? It was the last place that told me "no way can you machine this true as it is sprung loaded" and said they never touched the pressure plate for that reason. So even though it would fit their lathe, they would not do it.
So there I was with a brand new Type S plate and no-one to machine it, or worse, it just could not be done here, despite the Polish having success.
Then I thought I would try a proper clutch manufacturer and that's when CG said "No problem, we strip the clutch down and rebuild it." It only cost the same as just machining it anyway. And at last I was like "Yes! This sounds like the proper way to do it".
What could go wrong?
Well, you know when your at a point when you have make a decision that will take your life in one of two directions? One is sensible and involves an OEM clutch and torque limited remap, the other, well no-one's done it here yet.
Would you like to hear the rest of the saga?
