Tim,
I have been following along with your 914 brake upgrade as I had done the similar swap to 320i calibers a few months before. I followed an other train of thought and removed the original proportioning valve and replaced it with a Tee. Now, it feels like the rears are underpowered. Now the front wheels lock well before the rears come close. Your article on brake bias was right on time and explained the importance of the issue clearly, but left me wondering how it was that you needed a proportioning valve on your 914 with 320i calipers? With it backed out all the way, would the rear wheels lock before the fronts? My experience is quite different.
I am considering changing to a high performance street pad, or putting different ones on the back, but I don’t want them to grab too much because I do not have any proportioning valve. Are you running magnum/KFP on both the front and rear?
I think that my best move would be to put an APV in the console and install the original front calipers in the rear.
Your thoughts?
