Just wanted to update everyone on the kit.
I've had about 10 track days on the BBK using the Street Sport pads. Car's been driven by friends, professional racers, and me. Everyone's very happy with the bite and consistency of these brakes.
I am still on my first set of pads, and they have about 5 mm left on the front. Rear has a lot more.
