Believe it or not, there are a bunch of tweaks you can make to your tires to increase the feel of power in your car. Zurschmeide suggests starting with a more aggressive alignment. Dial out the toe-in that manufacturers specify so that the wheels are pointed straight ahead for more straight-line speed. Swap out the regular tires for a set of shorter tires to increase acceleration. Sure, this will make your speedometer read incorrectly, but it's a small price to pay for a quick time off the line. You can always get a new set of light weight wheels to mount those short tires on, too, but be careful here if you're pinching pennies. A set of carbon-fiber wheels may lighten your load, but they'll lighten your wallet by far, far more.
