i get such a kick out of people wanting to go racing in the g6. it is a nice 4 door sedan. was not made to exceed 120 mph. people wanting to put superchargers and get these cars tuned. are you kidding me.:crazy: if you wanted a fast car and something to race. you shouldn't of bought a g6. it is made to be a great everyday driver. i've been over 150 mph many times in my corvette. and i can't even imagine going that fast in the g6. tires aren't ratted for high speed. the brakes definitely wouldn't with stand a sudden stop from that speed. it doesn't handle like a sports car because it isn't a sports car. it is nice modding our cars to add a little spunk under the hood. but a performance car or sports car you are wasting your time and money. if you want to go fast might want to buy something else. :bash:
