Warped rotors are caused primarily because the rotors are not capable of handling the heat created during hard stops. The G6 is for all practical purposes a heavy car, weighing in at 3500 lbs. plus. Rotor overall size and thickness on the G6 is obviously not up to the task.
Things you can do to help avoid warped rotors.
1. When having to brake hard, and then coming to a complete stop, avoid holding the brakes. This causes the heat to be concentrated and retained where the pads are holding the rotors. This concentrated heat in just one area of the rotor, is what causes most of the problem. Also, when ever possible, pulsate the brakes rather than just standing on them, this also helps with keeping the temperature down.
Once you come to a complete stop, put the car in neutral, and remove your foot from the brakes. If you're on unlevel ground and the car begins to move, use the parking brake to hold the car.
2. Going to a dimpled and slotted rotor, will help evacuate the super hot gases that are created under hard use, and will help minimize warping.
3. The lower grill area of the G6 has ample room to build a cooling duct system for the front brakes. You can find all the parts you need at Home Depot. (don't laugh) One of my corvettes has this, and it has been put to the test at over 200 mph. It works. Most of the parts are found in the vacuum cleaner area. The hose and the attachments you use to scoop up the air are black, so you don't really see them, unless you're looking for it.
4. The next option, is a bit harder, and deals with the proportion brake valve. The trick is finding the right spring, in order to make the rear brakes work a little harder. Right now, as in most passenger cars, the front brakes do most of the work, this also shifts most of the weight to the front under hard braking, causing even more of a load on the front rotors, which contributes to more heat.
5. Ultimately, the best scenario is going to a bigger diameter rotor which is also thicker, this will require different calipers and pads. I haven't had a chance to look at the G8 braking system, but it might be adaptable to the G6 with some modifications.
Hope this helps.
