If you want better braking, you can upgrade the front brakes by changing from stock (54mm caliper, 10.25"rotor) to the 60mm caliper with adapter bracket and 11" rotors. Cordes recommended me to contact Rich Byrant to get a set of Hawk HPS pads. Man do they make a difference. I am convinced the 11" and Hawk has saved me and the car more than once with the crazy Toronto drivers.
