I am putting together a 4 cylinder vintage race car a friend who passed 5 years ago had started. I'm getting calipers from PMB, going with stock brakes for now. How many are running the stock brake pressure regulator in their race/track cars? Should I remove it and put in a proportioning valve?

With stock brakes I'm not sure I would do it. In my case I have one, with 911 Carrera brakes, but it stays full open all the time and I just as well could have a 'tee'. I've left it in the car mainly in case of rain where I figure I may at some point want to dial-down the rears, and also cuz changing any of this stuff would be a PITA.

... I've left it in the car mainly in case of rain where I figure I may at some point want to dial-down the rears... Actually, it is better to increase braking pressure to the rear in wet conditions. Reduced overall grip from the wet means less weight transfer to the front is possible, thereby allowing the rear brakes to do a greater proportion of the work. I am an advocate for adjustable brake bias in any race car. If you don't have it you are leaving time on the table. If you have it but don't know how to use it, you need more practice with threshold braking. |
