I have done something like this. Well used orginal rs master. The outlet closest to the bumper goes to a t piece in left wing . From this it goes to the left caliper and also over to the right caliper. For the other outlet it goes to a bias valve on the left strut then under the car where it splits left and right to the wheels. I did use a xr3i res bottle though.

Pretty sure this is like other setups in here
