I have been researching wheels for a bit and need to see if you guys can answer a few things for me. I have the 15" steelies on my car and want to go to either 16" or 17" wheels. Main question is, should I just get the 15" wheels or go bigger. I think the stock wheels are fine in either 15 or 16 but have considered 17's. The fact that I have an auto GT means I have to watch the weight of the wheels as well. What size wheels have advantages over others, ie 16 for speed 17 for handling and what should the max weight be? On top of all this, will I need to drop the car. I also need to know if the speedometer needs to be re-calibrated if I go with the bigger wheels. If so, how much???

Thanks
