Cool. I was under the impression that 3M treatment was more like $1500 so good to know it's cheap. Yeah I have an Audi S6 & had some break squeak issues due to "performance" brakes but once I had them replaced w/ something other than OEM the problem went away but even when they squeaked it wasn't as terrible as I read here. Man o man looks like I'm getting closer to ordering my first M! Thanks!
