Default Re: rear big brakes f/s

With the increase in brake pot quantity and diameters is the master cylinder changed? Nobody mentions that so I assume the answer is no.

My calculations show that the increase in oil required to move the SRT brake pistons the same amount as the NA pistons is 20%, this based on the difference in the area of the pistons. This means the MC pistons have to move more in the SRT with a corresponding increase in brake pedal movement. Would this be a correct assumption?
