Screw 14 piston i want brakes that go all the way around the rotor. 
I bet the torque on that lug nut is like 380lbs.

Not too smart (very little heat dissipation), but just for fun I'd like to see it too.

Little more info:
"507hp T5 motor
The factory C30 T5 gets a 218hp 2.5 liter five cylinder motor. Not a bad start, but "we wanted to be creative in every aspect," Don told us. So the team added sequential twin-turbos - a small one for instant spooling that runs up to 2800rpm, then a machined-barrel valve with its own Turbosmart wastegate operated by Turbosmart's e-boost controller switches over to the big turbo. There's a check valve on the "push" side of the turbos, and a Turbosmart BOV to prevent the turbos stalling each other.
In addition to the turbos, Mano decided a regular intercooler wouldn't cut it. So he developed an idea from Don who studied top fuel dragsters as a boy. The result was the Charge Air Cooler; an air-conditioned plenum chamber that super-cools the pressurized air as it passes through. It does this with a second AC evaporator coil that should provide consistent coiling and is a neat packaging solution that definitely deserves closer investigation.
The motor also received bigger injectors, a 3" exhaust and Powerchip software. With the turbos spinning at 25psi, the motor is claimed to produce 507hp and 468 lb/ft."
"Brakes
The team felt cutting-edge carbon/ceramic rotors were the way to go, but when they got to thinking about calipers they didn't want to do what was typical. "Since we were partnered with machine shop Sirius Custom Engineering in Duarte, CA, we decided to design our own calipers," Don explained.
The team eventually opted for 14-piston front calipers. Each side required a total of 137 separate parts to be machined. The calipers themselves are aluminum but each 25.4mm piston was machined from stainless steel.
The design also called for the calipers to be built in two parts, a front and back plate with a 15mm air gap in between. Each piston cylinder was then finned to take advantage of the air-cooling this gap would provide.
If you look at each front caliper, they are completed by two six-piston calipers, with a two-piston subdivision being used for the hydro-mechanical parking brake.
The rear calipers are again custom, this time restricted to six-pistons manufactured in the same way.
The front rotors are internally vaned 386x34mm with billet hats and a fully floating assembly. The hats and rotors are actually drilled internally to channel more air, while Evolve's logo was machined into the front face. The rear rotors are 362mm in diameter."
