Remot Brake Servo for 1982 mk1 golf... has anyone used this?

Hi Guys, I am currently running a custom pedal box by Mickey Marrows at GWERKS,

the system is made up of 2 master cylinders and a bias bar to regulate the braking power between the front and rear axles, I am using polo G40 calipers with OMP discs and pads.

I removed the brake transfer bar which normally runs along the bulkhead behind the engine and as a result, removed the servo entirely.

The pedal feels extremely stiff and the brakes are not great,

My questions are:

1. How is the pedal box setup supposed to improve the system?

I have removed the servo which seems to be an anti-modification!

2. Am i supposed to have a servo in here somewhere?

I was advised that I would not need servo as this system is extremely powerful.

3. Is there an original servo which would fit directly behind the brake pedal in place of the old transfer bar linkage?

I apologise for the confusion, this is bending my brain.
Many thanks, Wiw.
