FAQ

Q: What are the specs of a sprint car?

A: Sprint cars have very high power-to-weight ratios, with weights of approximately 1,400 pounds (640 kg) (including the driver) and power outputs of over 900 horsepower (670 kW), which give them a power-to-weight ratio besting that of contemporary F1 cars.

Q: What wheel type is best for racing?

A: Forged wheels are significantly lighter and stronger than cast wheels, and the look can't be matched with cast wheels. If you have a serious race car, they're well worth the investment.

Q: Where do I find the size of my wheel hub?

A: First, start with the wheel size for your vehicle. You can find that on the sidewall of the tires on your original wheels or the inside frame of the driver's door. Check out Tire Size Explained (Reading the Sidewall) for more. The wheel diameter (in inches or millimeters) is the fifth set of numbers and letters.
