Switching out your vehicle's heavy, factory steel or alloy wheels is one of the easiest bolt-on performance upgrades for your track vehicle. Just by switching to a lighter weight wheel, your car will instantly feel quicker and respond better compared to your stock wheels. The rotational force to get a lighter weight wheel to move and stop is less, therefore the engine and braking system of the car can now respond quicker. Reducing the unsprung weight by switching to a wheel with less weight will also reap benefits when cornering - as the shocks and springs will have less weight to dampen during rebound and compression - keeping the car more stable on the track.
Typically, the answer to a lighter wheel is purchasing a fully forged alloy wheel, however, this option can be expensive. There are many highly engineered cast alloy options that are more affordable and provide a great bang for your buck.

These wheels are designed to achieve the strongest wheel possible using the least amount of material. Many cast wheels are created the opposite way from a track wheel: form over function. The wheel looks good, so people want to put it on their car and dress up their ride. A track wheel is designed to provide the function of being lightweight over the appearance of the chrome clad bling you can add to your car.
