I only had the car a few weeks and had hardly driven it before I repaced the front brakes with a StopTech kit. Perhaps this is why I do not sense much of a difference. I have done this in the past to a different car and the change has heaven to earth. The pedal still requires as much force and there is vibration under hard braking even after new tension rods. Got to take the rotors to a shop for a thin cut to rule out slight run out.
