Chris,
You stated, "The front circuit cylinder should be on the bottom of the pedal box as it gets actuated first, and the rear cylinder on top. If they are installed wrong, then the rear brakes will be actuated before the front."
Is Shelby still using the basic original design of the pedal box with a bias bar placed vertically between the master cylinders?
Thank you,
David

In the 4000 series, both master cylinders are .75" with the upper one feeding the front. Admittedly this may not be the same as the 7000 series. But if it is, possibly the lines were originally connected to the wrong master? (Also, on my car, the front & rear calipers are the same size both the Girling [original] and Wilwood [replacement].)
