    Do you need a/c where you live? I pulled 120 lbs out of an s14 by deleting the a/c (and all related accessories).

    well that about sums it up then if you can't even go without a/c then you are left with only 1 option as far as I can tell and that is buy some really light weight wheels and get some 2 piece slotted cross drilled rotors with aluminum hats. so you can cut down on rotating mass instead of dead weight. it is call sprung weight vs unsprung weight. if you were to lose about 8lbs of sprung weight it is the same as removing 100 lbs of unsprung weight. so basically if you were to save lets say 16 lbs of weight from all 4 wheels and all 4 rotors then that would be the same thing as removing 200 lbs of dead weight in your car.

    hope that helps-

    ^^+1. Lightened crank pulley, too. GFB or kartboy without any CEL issues.

    That sub is pretty useless in my experience, needless weight, if not but 8lbs of it.
