Would you not need 4 of those as opposed to just the one 1g valve?

Just by looking at the 1g valve, it looks like the two out puts of the master cylinder go into the front of the proportioning valve, and then on the sides, comes out the four brake corners.

The 1g valve, two stainless braided lines from the master into the valve, and some pipe bending and magic to finish the job with stock tubing feeding all four corners.

Seems like it would look professional, and perform, if some care and time is taken.

Im sold on the 1g valve.
