Yeah but the LS Cobalt only has like 150hp stock...not really gonna spin tires unless you're trying or launching hard.

If you end up with a "SLIGHTLY" smaller diameter tire overall maybe you'll pick up a 10th of a second. Also, the 17" wheels will probably be lighter then 15" steelies so that will help since you will have a little less weight to turn.

Remember going to a larger size wheel (rim) at the same time you get a tire with shorter sidewall the overall diameter will stay nearly the same.
How is that? Lower weight wheels are easier to accelerate...same idea as a lightweight flywheel. Stock 15's steelies weight like 17-18 lbs, pretty light...most aftermarket 17's aren't that light unless they're low pressure cast shotpeened or forged which would allow them to use less material.
