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?
