I can tell you what I have experienced.
Car: E46 M3
Brakes: AP Racing with full floating front rotors.
Pads: Cobalt XR-1 front and rear
Tires: Yokohama A-005 race slicks
I share the car with the builder. He is a fast driver......could drive Grand Am if he had the proper sponsorship. I can almost keep up with him if I have some practice. We bought the BBK from an endurance team that runs the 25hours of Thunderhill. The pads will last 13+ straight hours in that race. Rotors much longer. (The only reason they sold us the kit is that they wanted an enduro BBK that could go all 25 hours without a pad change.....he wants the AP BBK back )
This last season we both ran HPDE, Open lapping days, Time trials, customer joy rides, test & tune and one race. I am guessing the equivalent of 25-30 days. Went through two sets of used front rotors and two sets of used front pads that came with the BBK. So I paid Zero $ for pads and rotors in 2013.
Performance: From either first hand experience or watching a GoPro I can tell you that the car will out brake any Porsche including 911 cup cars (haven't gone up against a 911 RSR), AMLM Audi R8, VLN Audi TTRS, World Challenge Viper, Trans Am cars (850 whp Nascar engine in a tube frame).

Not me nor my car but Eddie driving the E46 M3 Stammer car with Cobalt XR-1.
Seriously. E46. I just watched this again since the race finished...staggering driving from Eddie and car set-up...against a couple of "VW's"... Entry and mid corner is epic. His commentary sums up the rest for this track at least. Love it!
