I'm still considering 17" Wheel and tire combo that comes in at 6lbs per corner lighter. Although I'm not sure if I want to speed that much money for wheels and tires. Time will tell.

I would be very interested in your results after the pulley mod.
I am under-driving my Acura with aluminum pulleys that saved a bunch of weight, but I only had the car a couple of months before I did the mod, so my driving style was still evolving. I don't know how much of a FE difference it made. I figure turning the power steering pump, water pump, alternator, and AC at a slower rate should save some power. It will probably take 20yrs to recover the cost of parts alone, assuming a 1% fuel savings.
I still say all of this is lunacy when you can just go MT and outperform the most outrageously modded auto. It may be fun lunacy though.
