Don't knock it until you try it. The tiny wheels on that jack are narrower, which means less rolling resistance. Plus the jack weighs less than the removed parts, so there's less unsprung weight. When you consider that the jack is just holding the car up and not actually connected, that means NO unsprung weight. Since the wheels are smaller they'll spin faster, plus that they are metal, they'll give you more of a flywheel effect and we all know how flywheels store power for later use. And also being metal there won't be any sidewall flex. That'll make his LS the fastest, best handling one here!
At least, until someone adds NAWS, MSD, and Eibach stickers to their hoods and fenders, that is.
