2023-06-01 B-Spec BoB Adjustments

#34208 from Club Racing Board · Rule change · TB 23-05 (2023-05 Fastrack)

Summary

As printed in Fastrack

The popularity of BSPEC has brought heightened attention to the Balance of Performance (BoP). Given the wide diversity of
eligible cars and their designs, driving ability, car preparation/tuning levels, and other variables outside of SCCA’s control, the BoP
in this class has been remarkably close. As compared to IMSA’s job of balancing cars which are all professionally prepared, driven,
and highly instrumented, the job of our advisory committees and CRB is considerably more difficult. There are most certainly
outliers and cars which are superior under certain conditions, but in the absence of BoP regulations which vary from track to track
a perfect balance every weekend is not to be expected. The BoP is set by SCCA for what is perceived to be the ultimate tune and
best driver in a given car across the entire racing season and over as many tracks as can be reasonably sampled. If a car is not
prepared, tuned, and driven to its ultimate capability we cannot expect that it will be on par with cars of other manufacture which
