I read a long time ago someone posted that Spec had changed the formula or something like that. It was basically a bad batch. Chime in with any info please. I have a spec1 with that is on my daily driver and its already slipping. It is less than 6 months old. The shop I had put it in does great work. He called to see about getting another clutch and they are giving him crap. They will not warrant the part.
