Uhhhh think guys...

The materials are far from optimal...with optimal materials you could brake better on a smaller rotor ..... (you know why Porsche can use such a small (radialy) clutch on the Carrera GT>?? its ceramic...its tiny, it acomplishes what you canot with other materials with a smaller surface friction area)

I really beleive you could outperform these brakes with Ceramic brakes Of a smaller diameter...and smaller rotors might weigh just a tad more..

2Pi X Rad = Perimeter of Circular object (rotor here)

Like a 10 inch rotor..the material on the perimeter surface has to moove 31.XXX inches every rotation of the wheel

While a 14 inch rotor the same material has to travel 43.xxx inches every rotation of the wheel

For example a Ligher Material 14 inch rotor will require more energy (tq) to spin than a rotor with the same weight but smaller 10 inch radius
