What is Autocross?
Autocross, also known as Solo, is a sport that tests and sharpens your driving skills in a safe, controlled environment. A new course is set up for each event on a large, paved surface using soft rubber traffic pylons (that will not damage your car) to define a variety of turns and maneuvers. One driver at a time tries to negotiate the course in the lowest possible time. Speeds are normally between 40-65mph (most cars stay in second gear). Cars are grouped into classes based on performance potential and modifications. Autocross is a performance driving event and a safe way to learn how to drive your car at its limit. You not only learn how to handle your car at speeds that you drive daily, but you also:
- Gain confidence in your driving ability
- Enhance your driving ability on the street
- Learn the limits of your car's acceleration, braking and cornering
- Learn correct seating, hand, and feet positions
Autocross is also a social gathering of new and old friends, and above all, it's LOTS OF FUN!!!

NCR PAX Information
What is PAX?
The PAX (Professional Auto-X) Index has been used by SCCA® and other clubs for years. It is a handicapping system that attempts to account for performance differences between car classes allowing the drivers' performances to be compared. A PAX factor, based on performance potential, is assigned to each base class. The fastest cars have a PAX factor of 1.000; other PAX factors are a percentage relative to the fastest cars. Each driver's actual time around the course is multiplied by their car's PAX factor to calculate their PAX time. This PAX time is also called their indexed time or factored time. PAX times can then be compared across classes.
It is impossible to come up with a PAX index that is perfect just as it is impossible to come up with a class system that is perfect. Everyone believes that someone else has a softer(i.e. easier) PAX factor.
What is an Indexed Class?
An indexed class is a class that combines several classes into one class and uses factored times to compare the results. We do not get enough entries to populate the individual classes so we need to combine multiple base classes to offer competetive classes. By forming indexed classes. the factored (aka indexed) times provide a more equitable comparison of the results than the raw times.
2023 NCR PAX Index
The NCR PAX Index is based on the PAX/RTP Index developed by Rick Ruth that is based on hundreds of autocross events nationwide. The NCR Porsche Street Category is separated into base classes that map to SCCA® classes. The PAX factors for the corresponding SCCA® classes are used for the NCR base classes. The exception is Street Class 6 which contains street Porsches that are excluded from the SCCA® Street Category. For class 6 we use a PAX factor between the SCCA® Super Street (SS) and SCCA® Super Street Prepared class (SSP) classes.
NCR Class | SCCA Class | PAX Factor |
---|---|---|
1 | ES | 0.792 |
2 | CS | 0.810 |
3 | BS | 0.818 |
4 | AS | 0.821 |
5 | SS | 0.830 |
6 | SST | 0.841 |
For the NCR Porsche Race Category and for all non-Porsche classes, we use SCCA® classes as base classes so we use the SCCA PAX for the base class.
