lol at IA population and their "brake" common senses.
Brakes are more than just Pistons and Sizes.
Pistons alone don't define braking power. 12 pistons are just as good as 1 good floating piston brake if designed poorly.
There are more to braking than just the "pistons".
lol at people calling "unsprung" weight. When "real" company designs BBK, a lot of factors have been involved. There are things called floating rotors that reduce the weight of the rotors, etc. "Unsprung weight" only affects so much to the performance and power that it can be overlooked when compromised by the benefits provided by the BBK system.
Caliper sizes, pistons counts, disc brakes sizes, brake lines, fluid, etc. in the entire brake system is what really determine the brake. If it's that easy to design BBK just to Look cool, then anyone can do it.
The larger the BBK, doesn't necessary mean the better braking power nor the "loss" in HP performance. (this goes out to both the wowsers and the dissers about BBK).
Larger BBK designed right will help with the brake fades, as well as improve surface brake distribution. A good BBK will take less effort to apply the brake over the surface, keep the brake temp down, cool it faster, etc.
There're too much to explain, I suggest some of you do some readings before posting "hear-says".
To sum it up: 12 pistons doesn't really stop that much better. Nor the larger brakes will perform poorly because of the "weigh".
Just my 2 cents.
Back to the topic, OP, good find. I've been following that car nicely and the owner certainly did a great job.
