Okay you have talked me in to ordering a 10# for the rear and not worrying about the front discs . I have tried since I last read this thread to see if there was any difference in brake travel, and the pedal does seem to come up just a little bit higher if I hit it twice. Barely noticeable , but it is noticeable . I am all about safety and optimum braking so I'm going to place an order NOW .
