about how much lighter are 15x10 aluminum wheels as compared to 15x8 steel wheels? i have a feeling its a lot, which is probably killing my gas mileage. so i'm thinking about buying some new wheels.
also because i have the fabtech spindle lift in the front, would these wheels fit? i'm not sure because of the backspacing. i think its no more than 3.75" backspacing for the spindle lift wheels
one more question. my old stock 16" sport wheels and tires are sitting in the backyard, so I want to sell them. how much should i sell them for?
