Y ou can do this your self as long as your flaring tool will handel the SS line.

The upgrade MC will have 2 outputs, one for the front and one for the rear. Plumb the line lock between the MC and the distribution for the RH an LH front wheels.

There is no reason to have the brake lines the same length so why the coil is there I can't say. Manufactueres do coil the lines from the master to the PPV to compensate for flex in the firewall when the pedal is pushed though.
