In the case of a class with only one competitor, that competitor will receive 20 points.

12. SCCA Classes & Spokes Indexed Classes

Spokes’ “base” classes mirror the classing structure used by the SCCA. The most current version of the SCCA rules and car classification can be found here. In addition to the SCCA classes, Spokes provides a few indexed classes to run in, outlined below.

All classes are scored using the current nationally based PAX factors (The PAX/RTP values to be used for indexing competition can be found here). Indexed classes cannot combined (i.e. A driver cannot combine the street tire and X class and run in XT).

Street Tire – (shortened to “Tire” class) – Required for all SSR, Street Prepared, Street Modified, Prepared, and Modified cars using standard 200TW or greater street tires.  If a question arises at an event about the legality of a particular tire, the Board members present will decide. The class will be designated by a T preceding the car’s regular competition class (i.e. TASP would be Street Tire – A Street Prepared).

R Class – Required for all SSR, Street Prepared, Street Modified, Prepared, and Modified classed cars that are running non-200TW tires. The class will be designated by an R preceding the car’s regular competition class (i.e. RFP would be R-class F Prepared).

X Class – This is a “Pro” class and is open to any driver. This class is intended for persons seeking the highest levels of competition in the Spokes championship series. This class will be designated by a X preceding the car’s regular competition class (i.e. XCS would be X-class C Street).

Novice (N) Class – Novice Class times shall be determined by a PAX index. There is no year-end Championship for the Novice class. Soft compound, DOT approved racing tires or racing slicks are not legal. If a question arises at an event about the legality of a particular tire, the Board members present will decide. The class will be designated by a N preceding the car’s regular competition class. A driver is eligible to compete in the novice class if they have run no more than 6 autocross events (with any club) prior to running with Spokes. A driver is eligible to compete in the novice for up to one full season, or until they win the novice class at an event, whichever comes first.

U Class – Required for all CAM-C, CAM-S, CAM-T, XS, XA, and XB class cars. The U class is for RWD vehicles in the SCCA CAM or Extreme Street (XS) categories that may have extensive engine and/or suspension modifications, but run 200+ TW tires. The class will be designated by a U preceding the car’s regular competition class (ex. UCAMS, UXA, etc).


1. All entrants that enter the event twice must enter in the D-class as one of their entries.
2. Entry fee for running in D-class will be in addition to your first entry. Register twice, pay twice.
3. The D-class is not a competitive class, will not show up in the Pax or Raw time results, and does not have a points race or Year End Championship.
4. D-class runs must be taken in a heat that occurs after your regular competition class runs.
5. D-class competitors are required to perform 2 work assignments. The work assignments will be coordinated with the Worker Chief.
6. D-class is reserved to pre-register only. If you wish to double-enter the event you must pre-register both of your entries.
7. Only one class prefix will be allowed on your vehicle on a given run. Class prefixes include T, R, U, X, N, and D. Multiple prefixes may result in your times being disqualified. For example if you regularly run CSP in the Tire class, do not show up to the line with DTCSP on your car; mark your car as TCSP for your regular competition runs and DCSP for your Double runs.
8. The class prefix must be placed immediately before your class when displayed on your car. For example: DCSP is correct. CSPD is not correct.
