As far as I know, all the people I have talked to that replaced the prop valve with a tee were sorry they waited so long. They experienced no early rear wheel lock up or other strange braking behavior. They did like the much more solid Pedal and easier brake bleeding. I also think those who say never to do have never tried it which is fine. What you do have to get used to is a harder/more solid pedal so a slightly different brake pedal feel is required. I have a tee on both our 914 cars and the race car has equal brakes front and rear and as far as I know all wheels lock at the same time if I goof!
Good luck.
