[QUOTE=J08M3;4897947]Frank, Interested to see your pics and hear your review. Good work contacting AC about the product. But I can tell you it's clearly not billet aluminum.
+1 on the not billet point. I noticed this once I received my bar. It's not solid. Yet ACS still said it was billet.
But they might be confused because other braces, like the front strut brace they make for the E60 M5, are billet aluminum.
