Why?!?!?!? It would increase the rotating weight/mass of the rearend and affect torque/launching consequently. If I could I'd run the smallest, lightest rotor's on my FC. Gas slotted fronts, cross drilled and slotted rears I'm thinking.

not only the rear...but ive dirven cars with big brake kits on them in front and rear...13" rotors....jason its the other way around, maybe the unsprung weight becomes a little heavier but they increse the ability to brake by 100 fold...the larger the surface the more area heat has to disperse across....and if its slotted, or xdrilled and slotted, (i wouldnt recommend only xdrilled), then its even better at dispersing the heat

Why do you feel xdrilled is not good alone, but fine with slotted?

And after you have already mentioned the greater heat sinking capacity with the larger disc, why do you want to take a step back by drilling it (removing mass) anyway?

Unless you are running signifigantly larger tires(like diyman25) then the stockers with proper pads for your application, and ducting if your road racing is all the tires can handle. I road race regularly, and with stock brakes, Carbotech XP pads, and 245 R compound tires I can brake just as deep as the ZO6, and 996TT that I run with occasionaly.
Baer makes a big rotor kit with a bracket to move the calipers out. It requires 18" wheels, but I think that is what diyman has.
