[DeTomaso] Any interest in dual (no booster) brake MC conversion?

You can easily increase the mechanical advantage by mounting the balance bar a bit higher in the pedal arm and mounting the MCs a bit higher.
 
Next question?

I can email photos to anyone interested.  It really cleans up the front trunk.  Maybe not a good idea with stock calipers, but if you have big brakes, seem like the way to go.
 


FWIW, Geoff Peters has been struggling to make his GT5 stop after he ditched the brake booster to save weight (!?)

He's got six-piston Wilwoods on the front and four-piston in the rear.  He has gone through numerous different sized master cylinders in an attempt to get the car to stop properly, to no avail.  It still requires an enormous amount of pedal effort.  I drove the car from England to Modena and back, and it wasn't nearly as pleasant as it might have been otherwise.

The fundamental problem is that the pedal doesn't have enough mechanical advantage.  Normally when cars are available either with, or without power brakes, they have a different brake pedal depending on the application; the one without power has a much higher leverage ratio.

What is your reasoning behind getting rid of the power assist?
