i'll share my experiences since i've had 13 inch vx wheels, 14inch hx wheels, 15 inch volks, 15 inch 96 GSR wheels and 13 inch steelies on my car in the past 4 months.
for acceleration, 13inch vx wheels were the best, hands down. they weighed 9lbs, like the volks and had yokohama avs intermediate tires in 185-60-13's. now keep in mind, this setup is smaller than your typical rolling diameter. the 14 inch hx wheels had 195-60-14 inch falken azeni's, which are great for the street but are very heavy. the 15 inch 96 GSR wheels were awful, and although my car handled better laterally...it was miserable to drive around town as they must have weighed 18lbs a piece, plus tires...i'd say at least 35lbs.
the volks are second best, for acceleration wise and although they weigh the same as the vx wheels, the falken azeni's are much heavier and make for a larger and heavier tire/wheel package.
while i wouldn't trade for anything else besides vx wheels at this point, i coulnd't be happier with the volk ce28n's that are on my car, despite the 3 or so tenths of a second i'm probably losing in the 1/4 mile.
