brake master cylinders

[RobMatthews]

Sooo, looking at getting a pedal box for the track car,why is nothing ever easy!
I need help choosing the master cylinder sizes!
I have a kad 6 pot and 355 disks for up front and standard rz brakes on the rear.

from scouring the internet there are calculators out there but they require stuff like static weights on front and rear axle, maximum deceleration rates,center of gavity weights etc

ding dong im an electrician you give it to me i\'ll put it together but this calculation stuff is way over my head

Jon at Atomic has made a few calcs on sizing so he may be able to help.
 
I\'m using the Atomic/OBP box in my car and it\'s a good product but I have added a couple of additional braces to get a better pedal feel. Jon has taken this onboard and is revising the design to refine it.

I\'m using the same box.
