If you can i would definitely upgrade to the 13" brakes, after driving hondas for the past couple of years with their econo brakes, then getting into my car with the nice cobra brakes, i will never go back to small brakes again. Not only does it make it nice when you really need to stop, but i think that everyday driving is improved because of how much less effort is needed to stop the car. I also just put on stainless lines and i would say that they are worth it, the pedal definitely got a lil stiffer and more responsive, although i havent got a chance to really step on em and see how they preform cuz the rotors and pads are still bedding.
