Biggest brakes I've heard of

I was reading online, and I found a brake set from Alcon, in Britian, that is just scary big. Imagine if you will; 400mm front rotors clamped by 12(!!!!) piston calipers, and 380mm rear rotors clamped by 6 piston calipers. The cost for all of this? A mere $16 000 USD. Unfortunately, I haven't found any pictures of the set installed; although, I am still looking. Incidentally, I think it mentioned a minimum of 19 inch wheels.
