Nice looking brakes!
Curious as to why you upgraded. Were you having problems with your stock brakes or is this just a safety margin? I've owned two sets of stoptechs in the past and was very happy with them (I put their kids through college from rotor purchases alone)
I was hoping to get by without a BBK on the M. So far I feel like I'm borderline with race pads but am hopeful that some sort of ducting will get me by. Running 19's is not an option for me. What kind of tires are you running on the track?
