Hey guys I was just wondering if any one here got BC's? Ive had a few friends that have had them and never complain but I read threads before and some Audi owners say they are not that good. So if anyone can clear this up a little more for me that actually had them. I'm a new Audi owner so I done my research but haven't been to successful with some searches and I just want to see what you guys that been part of this family longer then me think? Thank you in advance!!
