Nah, no migraine from the numbers... I run a lot more complicated numbers at work every day. What *will* give me a migraine however is constantly thinking about the various options trying to make the best decision to only buy things once.
I tried a 7/8 bore MC with my current C6/C4 setup years ago when I first put it on... pedal feel was OK but the amount of pressure required to stop the car quickly with street friendly pads was excessive so I went hydroboost. That easily fixed the effort issue but required a lot more "stuff" under the hood.
Now with even more extra "stuff" under the hood from the turbos and with the hydroboost pushing the master too close to the wastegate for comfort I want to go back to manual for simplicity and room. A reasonable pedal effort even though the brakes are manual would be nice too-- and I know that can be achieved with correct component selection.
Still scratching my head on the dual MC with balance bar vs tandem master cylinder arrangement and the best rear caliper selection...
