Racing and HPDE on-track events
Watch some of the best road racers in America compete on the famed Sebring Raceway and participate in the HPDE courses. The HPDE consists of classroom and on-track time with a qualified instructor riding along in your car while you drive at speed (Levels 1-2 only)! Higher level and more experienced drivers can advance to levels 3-4 where you are doing everything but racing the other cars on track. Serious racers can apply for a competition license.

A list of requirements and costs for the events:
Any car in good working order... (so long as you pass tech)!
Join NASA: $45 (if you have an existing or NASA-sanctioned car club membership, such as INEX, you're fine)
Pay entry fee: $299.00 for the day
Have approved safety equipment (helmet)
Pass technical inspection. If you don't pass tech, your entry fee will not be refunded! (can be run through pre-tech locally, check website for details) The table under Event Rules should be a good baseline to start with.
Be dressed appropriately. No need for a firesuit and HANS, but you need to wear a long-sleeved shirt, long pants, and closed-toe shoes.
Have a state driver's license
Knowledge of Club Codes and Regulations
Seat belts in good working order
Mufflers (depends on track policies)
Convertibles require a 4 point roll bar
