Guys - I noticed those gouges too. I have not done the "forensics" to determine exactly what's caused them but it was something form the first (cheap) set of adapters that caused my whole dilemma in the first place. The mating surface of those adapters is not smooth so it could have been just the shape of the adapter's face, especially once the nuts loosened and there was nothing to keep the wheel centered. The new adapters are by comparison beautiful! Smooth billet mating surface and everything's staying together now. Moral of the story is either avoid changing your bolt pattern or - if you must - spend the $$$ for real adapters (wheeladapters.com is great!). That all said, I'll be putting Wilwood discs on the back within the next year or so, and the adapters won't be needed thereafter. And shame on TRANSDAPT for selling such a shitty, dangerous product (the first adapters I had).
