With the 2022 ProSolo Series fast approaching, the ProSolo Index committee met to review and update the ProSolo Index and class adjustments. Their recommendations were submitted to the National ProSolo Staff and the following changes will be implemented into the 2022 ProSolo ruleset:

  • STS to be combined into the S5 class. The STS class has been the least subscribed class and for 2021 it averaged 3.9 entries per event, only 4 times did it make the class minimum. Combining STS into S5 along with the other class adjustment will make the S5 class the third most popular class.
  • FSP will be moved into the S5 class. FSP has been somewhat out of place in the higher-powered S1 class requiring a wide spread in class PSI factors and often creating course-dependent results. The move will place the FSP cars into a class filled with cars of similar type and size while tightening up the PSI factor spread for the S1 class. While traditionally the mixing of tire type (200/R-Comps/Race tires) within a class is not ideal it has been done in other classes, so we feel this to be the right move for the FSP and S5 class.
  • Other notable changes: 
    • Drop the Formula Jr. Class
    • Add the new SST class (2wd) to Street Index class S3
    • Add the new SST class (4wd) to Street index class S4
    • Add XA/XB (2wd) to Street Index class S1
    • Add XA/XB (4wd) to Street Index class S4
    • Add EV as a Supplemental Class that would be eligible for points, contingency awards, and participation in the Bonus Challenge if there are five drivers in the class: not eligible for Super or Ladies Challenges due to unknown performance potential
