Brake Bias Bar for Street Car 2

[swall]

My younger brother is contemplating building a Cobra kit car and at the moment, he is stuck on the idea of using two master cylinders and a brake bias bar to handle the proportioning. After purusing Gillespie's book, "Fundamentals of Vehicle Dynamics", I have concluded that while bias bars may be fine for the track, where the braking conditions are fairly consistent, this would not be a good idea for a street vehicle, where there is a much more variable range of braking conditions that will be encountered. I'm thinking he should stick with a single master cylinder and use a hydraulic prop valve.Comments?

Use a tandem master cylinder with a Wilwood adjustable proportioning valve to control the rear brake bias.

I wouldn't think that you would want or need abs in a kit car but it would be a fun project.
