2024 Rules Updates
Interim Rule Changes
PCA Club Racing Rules Committee has published interim rule changes for 2024, effective immediately. Use the topical link to read the specific change or use the button to read the full announcement.
13/13 Abolished!
After careful consideration, and significant input from racers, shop owners, David Murry, and the National team we have decided the time is right to abolish the 13/13 rule.
- At-fault incidents will result in a 9-race or 12-month probation, whichever ends first, with the retention of your national championship points for all races other than the one in which the incident occurred.
- A second at-fault incident during the probationary period will result in a 6-month suspension from the program, after which the racer must apply to the race chair for reinstatement.
- This program change is retroactive to the beginning of the 2024 season and anyone currently on a 13/13 probation or suspension.
PCA Club Racing has been collecting data for many years and that data helped guide the decision to change the 13/13 rule. We believe that our racers will continue to operate at a high level, with a relatively low incident rate while competing for the coveted PCA Club Racing National Championship.
If you have questions or comments about this change, please reach out to me at info@pcaclubracing.org.

The New ME1 Spec Class for 2.7L Boxster & Cayman Models
The new ME1 class rules have been released and are available in the 2024 PCA Club Rule Book. (Download the Rule Book here.)
The driving force behind the ME1 is to create a class for the more than 43,000 2.7 liter mid-engine cars which Porsche sold in North America from 2000 to 2008. These are the less expensive base Boxster and Cayman models.
Conceptually, the rules for ME1 are much like the SPB and SPC in terms of the changes from stock that are allowed. In creating this new class there is an emphasis on potenial number of cars, cost containment, build similarity to SPB, and improved handling and power so that ME1 slots in between SPB and SPC.
A note on ordering the Flash tune for 986 versions of ME1. When ordering the Flash, order from the standard menu on the Softronic Software website. Order the Flash tune for the 2.7L 986 Boxster. Then specify in the instructions box that you want a PCA ME1 Flash tune, PN SFT-ME1-0004. Also provide the year or your Boxster, even though this information is provided when the Flash file is uploaded to Softronic during the tuning process.
