Luk clutches are fine as a stock replacement. I'd get a better throw out bearing than what comes with it. They seem to be the issue more than the clutch. I used a centerforce tob when I replaced the clutch, way beefier than the stock ones. I think one of the other ones people recommend is from national bearing.
