Yikes. I saw an STi at Lime Rock this past season lose braking and slide off into the grass with the left front on fire. Brake caught on fire and probably ignited the plastic fender liner. Pretty scary.
Enjoy the StopTechs. I have the same front/rear combo and love them. I finally trusted myself enough to do my first pad change on my own a couple of weeks ago, taking out the RS29s and putting back in the Street Perf pads for the winter. Not too bad. Did it while putting on the winter wheels/tires.
Do you have a StopTech setup on the 330Ci as well?
