TRSCCA Autocross
Autocross
Autocross, also known as SCCA Solo, is a competitive driving program that challenges drivers to navigate a course marked out by traffic cones in the fastest time possible. The events are designed to be accessible to drivers of all skill levels, with classes based on modifications and experience. Participants are timed on a course, with the fastest time in each class declared the winner. Autocross emphasizes skill and precision over outright speed, making it fun and challenging for enthusiasts of all levels.

#Class Championships
Competitors who complete a full season within the same competition Class will be eligible for the TRSCCA's Year End Championship for that Class. Competitors must be a registered member of the Tennessee Region SCCA
  • The minimum number of Events that must be attended in order to qualify for a TRSCCA Year End Championship is >50% of total Points Events in the year.
    • Example: If 8 or 9 Events, 5 are needed to qualify; if 10 Events, 6 are needed to qualify.
  • The Solo Chair will determine the number of dropped (and scored) Events used for Year End Points accumulation; Generally it is one more than the minimum qualifying number.
    • Example: If 10 Events, 6 are needed to qualify, highest scoring 7 Events are counted, lowest scoring 3 Events are dropped.
  • The Solo Chair will determine the minimum number of points to earn a Year End Championship, based on the number of Events. Minimum Points will NOT apply to the Novice Class.
    • Examples: 70 points for a 9 event season (counting top 6 Events), 80 points for a 10 event season (counting top 7 Events)
Novice Class: New competitors may compete in the Novice Class for up to one (1) full calendar year, or three (3) class wins, whichever comes first. Then they will be asked to graduate into the normal class for their vehicle. Novices (and new, non-Novice Class competitors) may be selected for the annual "Rookie of the Year" award.
Bump Class: After an event concludes, all drivers in a single-driver class will be grouped into a Bump Class and awarded points by PAX finish. Trophies and points for their original class will still be awarded. Bump Class will not include Pro or Novice competitors.
The 2025 Solo Championship is to be announced.

#Your Vehicle

Classing: Cars are classed by both their modifications and general potential. The SCCA has a brief "Introduction to Autocross Classes" that can help familiarize you with the basics, and the SCCA 2025 Solo Rule Book has specific class rules in Section 13 thru 20 and a comprehensive list of vehicles/classes in Appendix A.

Need help? Send your car's Year, Make, Model, Tire size & type, and any modifications to our Solo Chair and they will contact you to help class your car correctly!

Tech Inspection: Your vehicle must pass a Tech Inspection before every event.

Tech closes at 9:00a - there will be a $5 charge to tech after that time.

Items checked include:

  • Tires - no cords showing or other damage such as bulges, nails, etc.
  • Wheel bearings, shocks, steering, seat belts and suspension in good operating condition
  • Brakes - firm pedal with no detectable drop with car not running and proper level of fluid in reservoir
