CZP lightweight flywheels are CAD designed and manufactured from a solid piece of forged chromoly steel. They are designed to reduce weight and inertia for better engine response. Our chromoly steel flywheels have a combination of low weight and high thermal capacity that is specifically designed for all types of street or track racing such as Drift, Drag, Rally, Time Attack, and more. The reduced weight and inertia gives you a sharper throttle response and quicker shifts as mentioned earlier. These types of flywheels are designed to increase the main airflow which helps cool the entire clutch. It has been tested up to 18,000 rpm without failure. CZP flywheels are designed and tested to ensure the safety and quality of each flywheel. Years of R&D have given us the knowledge and first-hand experience to wisely choose the best material to manufacture steering wheels that will exceed your expectations. All CZP steering wheels are made from 4140 CHROMOLY-STEEL. CZP steering wheels are SFI certified and meet the performance standards of the automotive and motorsports industry.
