A. VEHICLE ELIGIBILITY: Competition is open to all vehicles conforming to the Open and Ladies National classes and National Supplemental classes, as defined by the 2024 Solo Rules. CAM, Xtreme Street & Club Spec Rules can be found here.

B. DECALS: 

  1. The Tire Rack® is the title sponsor for all 2024 SCCA® National Solo® events. Participants in these events are required to run the title sponsor decal, which is a windshield decal that is to be used at the top of the windshield. Vehicles without windshields or with plastic windshields may place the decal on the front of the car in a highly visible location approved by the Chief of Compliance. Decals other than the official Tire Rack® decal, except those required by National Tour Staff, are prohibited on the windshield.
  2. Additional required event decals are one SCCA® (on the front) and 2 CAM decals (one on each side).
  3. A 2D-style barcode is used by National Solo for each competitor's helmet. This barcode should be affixed to the competitor's helmet in an accessible location for scanning at the start line. Any and all other barcodes (SCCA Regional or for other events) must be covered during the event so the National Solo barcode is the only one visible.

C. TECH PROCEDURES:

  1. Safety Inspections (Solo Rules 3.3.3) should be completed at the event site and will be completed by competitors using a Self-Tech Form.
  2. Solo Rules 3.7 Vehicle Identification will be checked. The official Tire Rack decal and tech stickers are the only decals permitted on the windshield.
  3. Drivers should come to tech with completed Tech Forms, helmets and their vehicles should be "race ready" with numbers and class shown on the sides of the vehicle. Tech will provide any required decals.
  4. Competition vehicles that have a required minimum weight (CAM, XS, Street Modified, Prepared, Modified, and Kart) will inform Tech of that weight so the weight and vehicle wheelbase can be posted on the tech sticker. This is to allow other competitors to know the declared minimum weight and to reduce any delays at the scales during event impound procedures.

D. PENALTIES FOR INCORRECT NUMBERS OR BARCODES:

  1. Tech will confirm vehicle identification (Solo Rule 3.7) and helmet barcodes are compliant. The vehicle will not pass tech if not compliant.
  2. Competitors at the start line with the wrong number on their car, 2 sets of numbers, or the incorrect class showing will receive a warning for the first offense, a cone penalty for the second offense, and may receive a DSQ for three or more offenses at the same event.
  3. Competitors at the scanner with more than one (1) barcode showing on the helmet will receive a warning for the first offense, a cone penalty for the second offense and may receive a DSQ for three or more offenses at the same event.
  4. A driver at the scanner or the start line without the appropriate helmet decal (Solo 2025) will be directed away from the start and lose the run.

E. IMPOUND PROCEDURES: 

  1. All competition vehicles will be impounded per Solo Rules 6.10 to assure that competitors have complied with the SCCA National Solo Rules and the Supplementary Regulations for the event. Car information verification will also be conducted in Impound.
  2. Vehicles will be impounded on both days of competition in your assigned grid area. After your last run each day, return to your original grid position, except as noted in section E.7 below. The driver of each vehicle or a designated representative must remain in the grid/impound area near the vehicle during the impound period. Karts will be allowed to be driven to the scales under close supervision by event officials. Impounded vehicles may be held until the results are audited.
  3. Impound officials may inspect cars during impound and may require removing wheels and or components as part of the inspection procedure. Competitors are responsible for performing these procedures as required and for using proper equipment (e.g., jack stands to safely support a raised vehicle). Competitors are responsible for having appropriate rules and documentation of specifications
  4. Competitors may observe but Impound inspectors must not be hindered in their assigned duties by anyone in any way.
  5. Impound does not act on hearsay information regarding competitor concerns. If competitors suspect a rule violation, they should file protests in accordance with the National Solo Rules. Section 8, Protests.
  6. Vehicles under protest will remain in impound. They may be escorted by a designated Impound or Protest Committee official to another location as instructed by the Protest Committee.
  7. Classes that have minimum weights are required to be weighed. It is the competitors’ responsibility to know if their vehicle has a minimum weight requirement.

F. SOUND POLICY: Refer to Solo Rules Rule Appendix H. Sound requirements are strictly enforced.

G. TIMING AND SCORING: Refer to Solo Rules Rule 7

  1. The total score for class competition will consist of the best-timed run from each Day 1 Session, combined with best-timed run from Day 2 Session (all run in one day) to create one time.
