My Dart is a street/strip deal that runs 10.0's. I started with 73 disk on the front and Wilwoods on the rear, factory non power 7/8" (I think) mc through a 73 proportioning valve. The car stopped great, it was like the car sat down when the brakes were applied. Hemi Fred made me a good deal on a set of Strange fronts so I added them, the mc was leaking so I bought a 1 1/16" aluminum mc to replace it. The car would hardly stop and the pedal was hard as a rock. I installed an adjustable proportioning valve, had it in the front and rear, no help. I them bought a 15/16" mc from Dr Diff. Better but still not what I wanted, in the end I gutted the factory proportioning valve and just running the rear brakes through it. The fronts are on a T with the line directly from the mc.

The car stops fine, just not as good as the original set up. If I ever need to replace the mc I will use a 7/8" bore.
