I believe it was Karl that reached out to Porterfield to get the application for our cars, but I could be wrong. Stuart indeed knows his stuff, though
I remember reading Karl's thread a long time ago and it inspired me to get the pads, too. You are right, they're super quiet and really clean. I just got an Audi S6 and I've been battling the **** out of that dust. Forgot how bad it can be!
