Off the top of my head, the rotors are 273mm in diameter. The majority of the upgrade, on the rotor side of things, is that they are ~7mm thicker than standard (266x13mm I believe) while also being both vented and slotted.
The new calipers are 4-piston compared to the factory 2-piston items, and at a rough guess there would be a good 50% extra pad area and 50% extra piston displacement which should give evenly distributed pressure and plenty of grabbing power for road usage and trips to the drags. I wouldn't suggest that these brakes would be ideal for regular circuit work, but certainly all maths suggests that they are up to the task for the occasional visit to the six-weekly sprint sessions we have up here at Queensland Raceway.
Currently the rear brakes are standard, and as they do a minimal amount of work under hard braking I will probably leave them as is unless I experience severe problems with brake imbalance and can't dial this out with a bias valve.
