Since the SRT-6 has a lighter wheel for additional help in 0-60 speed. I would guess light wt. wheels would help slightly. But light wt. wheels bend and brake alot easier BEWARE. And they don't guarantee that. My guess stock wheels 17-19 lbs front, 19-22 rear. Light wt wheels are under 15 lbs. The SRTs are probably over that because of factory LIABILITY !!!
