I haven't decided yet. I'm not adding them right now, but if it looks like I need to then I'll consider it. I don't mind the front being slightly wider than the rear. By my calculations, I think each front will be 1 to 1.5inches wider than the corresponding rear. I'm also considering only installing the highlifter lift on the front. might perform better with a slightly higher and wider front end. I think it's already almost an inch wider on each front from the factory, so I'm not expecting a dramatic difference between front and rear.
