I'm currently upgrading to rear disc brakes and the car has had no proportioning valve for years running a 15/16 bore Chrysler style master. I'm doing so due to the fact that I've been killing Wilwood rotors on the front after only a few events and always using the last turnouts at the tracks I attend. I'm putting a valve on the line going to the front brakes (race car only). In searching around on this there seems to be quite a difference in opinion on it's location.... Noted a few of the brake parts manufacturers recommend this. Thoughts?
