Flex fan

I'm using one, 17" if I remember right, and either a 1/2" or 3/4" spacer to move it closer to the aluminum radiator... It weighs a LOT less than the stock fan. I didn't weigh the original after I took it off. I'd like to see how much weight I'll have shaved off when I get done. I bet it's a LOT. (Gotta make up for my fat ***).
