Hi, I am in the process of refreshing a 914-6 GT tribute car that was built for PCA solo events in CA and has been mostly in storage for several years. The engine is a 2.4 that was built by GD racing in San Bruno. The suspension and brakes are 3.2 Carerra. I pulled the calipers and they are at PMB. New soft lines are going in. I was somewhat surprised to find the stock 914 brake pressure regulator still in place. There is no after market proportioning valve.
The car will be used a few times a year for vintage wheel to wheel and then some PCA DE events. I have several years of experience racing vintage FV. As I got older and saw several buddies get involved in some nasty open wheel tire to tire incidents I decided I wanted fenders and more metal around me. I am not the most aggressive driver in the world and this car will remain street legal. I also want it to remain as period correct as I can get. I don't want to go down the rabbit hole of cutting a ton of metal out of the car, etc. Should I pull the regulator and put a T in and proportioning valve in the cockpit? Should I leave as is and see how it performs? If I leave it I will send to PMB to have them rebuild it. Cheers, Jerry |

Great looking car. Call up PMB and talk to Eric. He is very busy but still loves to talk about this stuff and is a wealth of knowledge. It's function is to keep the rear calipers from locking up before the fronts. It doesn't limit normal braking.
