I have several hours in my brake set up and I place a high percentage of good lap times on braking. Right now it is perfect but the radio tray is flexing and I use quite a bit of exponential curve to make them smooth and easy to use. I am going to go back to the drawing board and get the front brake more involved. If it reduces or eliminates the flex, I will be surprised. I have noticed that many of the pro- drivers use stiffeners and they all use brakes at a way higher level than most club racers, some use a ton of drag brake and I'm just not good enough to master that...I've tried and it was a disaster.
