A. VEHICLE ELIGIBILITY: Competition is open to all vehicles conforming to and/or eligible to run within the 2025 National Solo Rules and the CAM, Xtreme Street & Club Spec Rules, which can be found here.

B. DECALS:

  1. The Tire Rack® is the title sponsor for all 2025 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) (legacy SCCA wheel decals are no longer accepted) and 2 National Tour 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, bar codes for other events or for other drivers if you are sharing a helmet) must be covered during the event so the National Solo barcode for the driver pulling to the start line is the only one visible.
  4. Solo 2025 Tech decal on each competitor helmet, signifying that it has been teched and is compliant throughout the 2025 season.
  5. Event Tech decal placed on the upper or lower left of the windshield of the vehicle (or other pre-approved location), signifying that the driver has gone through check-in/tech.
    • "2" decal placed next to the tech decal if the vehicle has two drivers in the same class.
  6. Decals, including Class letters & Car numbers, must be placed on the vehicle as shown in the document below. Class letters and car numbers must be in a color that strongly contrasts with the car’s paint color for maximum visibility. (Pro tip: Wondering if your letters and numbers contrast? Take a picture of your car in grey scale, are your Class letters and Car numbers clearly and easily seen? If not, they do not have enough contrast).
    • All SCCA- required decals and some contingency decals are available at Tech. See below for details regarding placement of required decals.

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. Vehicle Identification verification is the sole responsibility of the competitor (Solo Rules 3.7).
  3. The official Tire Rack decal and tech stickers are the only decals permitted on the windshield.
  4. Competition vehicles are required to have a tech decal complete with the following information, affixed to the upper or lower left hand corner of the windshield (or other pre-approved location by the CTI or their designee). Vehicles that present to grid without a current event tech decal will not be allowed to proceed to the start line until a new tech form is complete for each driver and a current event tech decal is placed on the car.
    • Car Number(s)
    • Class(es)
    • Event Name
    • Event Dates
    • Minimum Weight (if applicable)
    • Wheel Base (if applicable)
    • 2 Driver vehicles may receive a "2" decal to place beside the tech decal to indicate to Grid/Impound that you are a 2-driver vehicle.
  5. When you have made your way through the tech line, you should have:
    • Received all your required vehicle decals
      • Including your Event tech decal & "2" decal, if applicable
    • Had your helmet teched
      • Received your Solo 2025 decal, if necessary
    • Turned in your completed & Signed tech form
  6. The CTI can, at any time, be asked by the Chief Steward to conduct an inspection of a vehicle per Solo Rules 5.6.B.

D. PENALTIES FOR MISSING DECALS, INCORRECT NUMBERS OR BARCODES:

  1. It is the sole responsibility of the competitor to ensure vehicle identification is compliant with Solo Rule 3.7, that helmet has been teched and has a Solo 2025 Tech decal, that the barcode is compliant and that any non SCCA National issued bar codes are completely covered (including covering non-driver barcodes if a helmet is being shared).
    1. Penalties may be assessed if class letters/numbers are not compliant, if helmet tech decal is not affixed and/or if helmet barcode is not complaint.
    2. Unused class letters or car numbers should be completely covered or removed from the vehicle so that times or penalties are not issued to the incorrect driver by Timing and Scoring or by Course Workers.
  2. Competitors at the start line with non-compliant car numbers or class letters will be allowed to complete the heat they are running. An event official (Chief Steward or Event Lead) will inform them of the non-compliance and let them know the deadline for remediation. If remedial action is not taken by the deadline, a penalty may be assessed; penalties include the addition of cones or a DSQ (See B.4. above for decal information).
  3. Competitors at the start line with the wrong number on their car, 2 sets of numbers, or the incorrect/too many classes 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.
  4. Competitors at the scanner with more than one (1) or an incorrect 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.
  5. A driver presenting to grid without the appropriate Event Tech decal or helmet tech decal (Solo 2025) will be directed to the Tech/Impound area to complete a new tech form and receive an event tech decal or get the helmet inspected and decal applied.

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.
