    * The "Speed" of the animated Race Car does not correlate to the speed of your car on the track. It just gives you an indication of the "relative speed" between products. Our Speed tests lists the actual track speed measurements.

    What Makes the Wheels Important

    Wheels are the biggest source of speed. With the right wheels, your car will race past the competition to victory. Less friction between the axles and the wheels and between the wheels and the track will help you bring home the trophy!

    Weight Tips and Placement Hints

    Lighter wheels turn easier (they require less inertia). Lighten your wheels, as much as your Rules allow, which will give you a fast start out of the gate and faster speed down the track.

    A lathed wheel means the wheel was turned at a high speed and "sanded" with a cutting tool. Lathed Wheels are perfectly tuned around the axis of rotation giving you the highest performance.
