Great write up, thank you for taking the time to do it. I feel like one of the issues of the stock 1ers is the very soft side to side resistance up front. This allows the front to lean so much that there front tires roll over from added positive camber and you suddenly lose contact patch, grip, and end up understeering while all kinds of rubber flexes and keeps it unpredictable. This is why a lot of people like the e92/93 m3 front sway bar. I think it and the strut brace both keep the front flatter which helps avoid some of those problems. Glad you like it.
