944 and CB brake bias question

[DWP]

Gotten to a point of total confusion Time to make a decision.
I am using a sandrail type frame to build a street Car.
1.7 porsche engine 944 rear brakes with single caliper.
CB performance front brakes, lowered spindle, ball joint.
CNC brake pedal assembly with bias adjuster bar.
I can drill the front drum for 5-130 stud pattern.
AS most if not all the weight is in the rear of the car any problems with this setup? My concern is too much brake in the back,
Dave
