Andy @ South Bend replied to me and asked a few key questions (what exact clutch kit, what FW, etc, etc) and went on to recommending that I re-break in the clutch as it's been seen before that the Feramic can glaze over.
Keep in mind that I bought this clutch kit from Avalon quite some time ago through one of their specials and didn't install it until I put in my 605's. I ordered their Stage 4 (at the time) which was the hybrid full face Organic/Feramic disc with the HD PP which I then mated to the TTV single mass steel flywheel.
And while the clutch didn't see more then 9k miles, it did get to see quite a bit if hard driving, launches and track time... All that abuse and it was still easier to drive then the old OEM clutch that was in the car, I was amazed.
So, I re-broke in the clutch but same thing happened it would slip every time I would get into boost from 3rd gear (from boost on-set), I then tried dialing down the boost ramp and the clutch no longer slipped. So it was obvious to me the clutch had to come out and that it just could no longer hold the power. I didn't understand why or what could have caused it to fail so soon but that was the case.
Either way, once I had a chance to pull the clutch kit from the car (after it was recovered by the Police, etc) it became clear that it was no normal failure. Both materials had lots of life left the PP looked good as the flywheel. Then I noticed the clutch disc itself had crack leading from every spring causing the disc to flex.

I emailed the pics to Andy and he said that is an older disc design and that they no longer use it because of similar failures.
That said, I sent the whole kit and FW back to SB to have the disc replaced and the rest of the kit checked and machined back to new. I can honestly say that at this point there is no other Clutch manufacturer that I would give my money to before South Bend. Even before this I was recommending SB to my friends looking for a good solution for their cars (some did end up buying a SB) and now of course I am even more inclined to do so again for my new project and anyone else that happens to ask me for my opinion.
After some of the negative threads recently about Clutches and such I thought it would be good to share my story and know now why I made the right choice going with SB, and believe me it was a lot of reading and research before I came to terms with my choice as many of you know there are a lot of options out there and the S4 is not nice to clutches when driven hard.
