My setup weighed 41.8lbs...thats with spindle, hub w/ 3" arp studs and lug nuts, bearings, lower bj and steering arm, camber spacers, rotor and hat, calipers and pads and all associated fasteners.

It is heavier than the previous setup posted...i kinda missed the OP asking to lose weight, i wanted a max braking setup! However I do run 18×9.5 wheels that only weigh 19lbs each so that helps balace it out lol
