This is a universal set up for anything really, due to space constraints I need the M/C's coming back into the cockpit to which there will be a heel plate over the top.
Interestingly, the M/C's that come with it as standard are 0.625" for the front and 0.75" for the rear. Funnily exactly the same I had for my red top powered Mk1 escort donkeys years ago on a homemade bias pedal box.
From what I remember the brakes were phenomenal on my escort with no servo. I was running Austin Princess 4 pots on front and sierra calipers on the rear.
I know a lot can do with bore sizes (area) of each caliper piston in comparison to how much fluid each M/C can move.
As a ratio between front and rear, I know the bore sizes of the M/C's are right but I havnt gone to deep in calculating the total area of pistons in comparison at this stage. But theres a simple formula I have from my days at college doing fluid dynamics to work that out.
As you rightly said, you dont have the luxury of road test shakedown, and need to drive in anger from the start.
I have the luxury or buying different bore sizes of M/Cs if need be. My gut feeling from experience, is it "should" be fine, or certainly as a starter for 10.
Ill let you know either way.
My biggest concern is floor mounted brake with top hung RX8 loud pedal.......... Ive never had the need to practice heel and toe braking and changing down on the road.
And at my driving abilty on the track ( or lack of) , Ill probably still not need it for several months/years.
I just hope the funny arrangement doesnt hinder the option.
