Stock 24lbs alum 12lbs when I changed mine. If you are really desperate to save the weight it's an option. I personally would not do it again. I understand there are different versions of the aluminum one and I had alot of hours putting one in my car.
I got to get weight out of the front of the car. I'm running Limited 8.5 at my local track. http://www.maliburacing.com/iceman/lightweight_radiator_support.jpg This is what i was planning on going with and using a smaller radiator, fiberglass hood and bumpers. Tubular support only weighs 7 pounds.
