So, because this bothered me so much, I did a quick analysis between my setup that was pulling hard left braking into turn one and the setup Scott sent me, which I then modified a little.

I was surprised how similar our setups were, mostly very minor differences, the only significant differences where in the spring rates, but i have summarized below the major differences:

                                               Scott's                    Mine
Front Springs                             219                        210
Rear Springs                              175                        201
Rear Slow Rebound                      3                            6
Rear Fast Rebound                       2                           6

The rear rebound does directly effect the cars behavior under braking, the weird thing is that you would normally need a higher number to slow the transfer of weight off the rear tires and keep more weight on them under braking.  So reducing this number should have made the problem worst  .
