Having had an ABS unit fail on me once was not a nice thing to have, the pedal went rock hard and did nothing at all just as the lights changed to red.
There was no traffic and the seat still bears the grip mark of the buttocks that were clenched on it.

Nice idea, but my own personal opinion is it's a lot of hassle for limited gain and dont forget the IVA and you need a 60/40 split for effort front to rear.
Ford fit neat little valves to reduce rear pressure and again for the IVA bias adjustment must be fixed and non adjustable so negating any benefit.

Do all these "adjustments" after the IVA.;)
