How about just putting heavier wheels on your car? I have a set of 15" alloy rims that weigh ~20lb each and I definetly notice a lack of acceleration with them on, compared to my normal 14" steel rims and tires. I should test it but given equal rolling resistance heavier wheels will help a bit with the gliding phase. Of course there are all sorts of downsides to heavy wheels but none of them stop the ricers from putting the biggest rims they can fit on many small cars.
