Decrease Weight in F600 W/593HO
#33661 from Carl Wassersleben · Not recommended · Minutes (2023-02 Fastrack)
With regard to performance parity of the Rotax 593 HO with the 600cc motorcycle-based engine cars, the Club Racing Board has
been carefully monitoring class performance at selected U.S. Majors Tour events as well as at the Runoffs, and no clear
advantage has been evident for either drivetrain so far. We will continue to monitor performance and plan to expand data
collection to other tracks this year. Although the effect of adding or removing weight can sometimes be difficult to discern, a
definite correlation between weight and lap times exists, and it has been shown to be a good way to fine-tune performance
balancing. To date, we have not received reports of or observed unusual or extraordinary weight-related chassis failures. In
general, chassis age and adding weight, power, better tires, and heavier power plants each could contribute to additional
stresses on a chassis. As an alternative to meeting minimum weight purely by adding ballast, a higher minimum weight can help

to alleviate the negative effects of such additional stresses on the chassis by allowing the cars to run more structurally sound
frames and strengthened components as the performance increases, which often increases weight organically and overall adds
safety.
