The benefit of Non-Wing Sprintcar Birdcages

Increasing the rear arm angle by running the torsion arm on the lower pick-up point on a non-wing sprint car birdcage (available for sale here) can potentially provide more drive, especially coming out of turns. The rear arm angle is a crucial aspect of the car's suspension geometry, affecting how weight is transferred to the rear wheels during acceleration.

By increasing the rear arm angle, you :

Increase Forward Bite: The term "drive" in racing often refers to the ability of the rear tires to grip the track and propel the car forward. A higher rear arm angle can enhance forward bite, allowing the rear tires to maintain better traction as the car accelerates.

Improve Weight Transfer: A steeper rear arm angle can influence weight transfer to the rear of the car, pushing more weight onto the rear tires. This added weight on the rear can enhance traction and help prevent wheel spin during acceleration.

Enhance Mechanical Grip: The change in rear arm angle can affect the mechanical grip of the rear tires, influencing how efficiently they interact with the racing surface. This can be crucial for gaining traction on different track conditions.

However, it's important to note that adjusting the rear arm angle is just one element of a comprehensive suspension setup. The impact of this adjustment can vary based on factors such as track type, surface conditions, and the overall car setup. Experimenting with different rear arm angles and closely monitoring how the car responds on the track can help fine-tune your setup for optimal performance.

The biggest part of being a successful racer is all the preparation that goes into the car before going to the race track. Take the time to make sure the chassis and suspension components are square - straight in all planes when measured against a common reference point.
