Maybe someone can give me a second opinion on whether my car should have a brake upgrade, as a friend of mine keeps insisting. I'm driving a 2007 Cobalt SS coupe, with a swapped-in Hahn turbo and exhaust system, putting out about 380 hp at the engine and 330 at the wheels. Apart from a short shifter, everything else is standard equipment and seems to operating fine. But this friend of mine keeps telling me that I've got to replace the standard brakes with more serious stuff. Is he right? The car has had no trouble stopping so far, but I haven't had to hit the brakes suddenly while traveling at a high rate of speed. Bill Hahn said nothing to me about upgrading the brakes, only that I should have a heavier duty clutch installed when the current one starts to slip. Thoughts from out there in forum land would be appreciated.
