How much better do the larger 11.75 inch rotors perform over the standard A-body discs? Is it a noticeable difference?
i went from the 10.84 to 11.75 rotor upgrade. it seemed to stop better, but i am now going with the above bracket to put wilwoods on there. why? more clamping force. 4 pistons have more clamping force than a 1 piston pin or slider style.
Some good answers above, but the real increase in braking efficiency is due to the greater 'swept area' of the larger rotor. Because of the increase in diameter, the pad is in contact with more area (square inches of contact) of the rotor per revolution of the wheel. The larger the diameter of the rotor, the more area the pad will contact during a single revolution of the rotor. Therefore, more 'swept area'.

Sounds right, I asume it will give better stoping power but how can a pad of equal size (constant) gain more area of contact from just increasing the size of the rotor? Are you saying that the caliper pad was not making full area contact on the smaller rotor, and now that the rotor is larger, it is? Maybe I'm not seeing the science behind it.
