When building a race car, power doesn’t mean anything without a properly built chassis to hold it all together. The frame, suspension and chassis are closely related when designing our 2018 build. #top ten


2018 Wheel Assembly.png

A major difference this year is going from 13-inch wheels to 10-inch wheels in order to reduce the weight of the vehicle. Tires are definitely important because they develop all the forces that cause the acceleration, braking and turning. We select our tires and work our way inwards, frame doesn’t start until suspension geometry is determined based on where the tire is.


Some difficulties encountered with suspension were fitting all the components and redesigning everything in the wheel. A huge opportunity was changing the brake calipers to take less real estate, as a result, it saved a pound and a half. Suspension is important because all the force that occurs at the tire needs to be able to handle maximum amount of acceleration, braking and cornering.

The difference in the frame from last year is modifying how we mount the suspension to the frame, engine mounts, tube sizing, and pick up points.

Modifying the engine mount tubing saved two pounds compared to last year. Being able to handle the stress and driving conditions on the track all play a major factor when designing the frame.
