Although calipers may be on your spindles, that weight isn't rotational, and in all realism, really doesn't do almost anything especially given that there isn't any more than a couple pounds to be saved. Aside from that, you can get the willwood calipers, inluding larger rotors and lines for half the cost of just the spoon calipers. That's a case where you really are just paying for a name.

As far as weight savings, with no spare, and a carbon hood, and almost no gas, mine weighed in at 2540 at the scale at Moroso. In order to dump some weight, without having to sacrifice on convinience, the spare tire, a carbon hood, carbon fenders, aluminum a/c braken, lighter wheels, lighter axles (carbon drive shafts), lighter rotors (two piece, or if you have bog money, carbon/ceramic), lightened flywheel, knife edged crank, manual steering rack, rather than power, in which case you save the weight on the rack it self as well as the pump, and parasitic drag, plus, the manual won't lock up if you run it without power steering fluid, and is also easier to turn without power steering fluid. Lighter cam gears, but don't do underdrive pulleys, as they are larger, so what ever weight you saved, you probably got back on size, it just puts a little less strain on the crank. Electric water pump, if you have some cash laying around is cool, as it removes one more thing from your crank pulley. Lighter pistons and rods, um.....well, other than the remainder of your interior, I'm not sure there is a lot else you can do. I'm sure there is some stuff I didn't remember to list, but that's pretty much it that I can think of....
