What to expect at the track:

  1. Entry: When you enter the track, you’ll receive a tech card after paying your entry/participation fee. Entry will be limited to 40 vehicles, first come first serve.
  2. Tech: After receiving your tech card, you’ll drive your vehicle to Tech, where a simple safety inspection will be performed on your car.
  3. Staging lanes: Once you have passed Tech, drive to the rear of the staging lane with your Group A, B, or C and get ready to drift.
  4. Drifting: When it’s time for you to enter the course, an official will motion to you to pull up and then allow you go on course. At the end of your run, slow down and exit the track properly.
  5. Return to the staging lanes and get ready for your next run. We will alternate between groups throughout the evening.


Driver Groups:

This section explains the different driver groups we have at all amateur events. Drivers are broken into Groups A, B, and C based on experience. Driving in the right group gives you and all of the other drivers in the group the best experience on track. Trying to drive in a group that you are not ready for is dangerous and will not happen.

Group A is for the drivers that have all the required safety equipment, meaning fire suit, shoes, gloves, appropriate roll cage, etc. These are the guys that have no issues making it around the track and are working on getting closer to other cars and running a better, faster line. Just because you have a roll cage does not put you in Group A.

Group B is for the drivers who are making it through the course without issues, i.e. not spinning, not understeering. They are running a good line; it may not be the best line, but they are learning. They are starting to go faster and trying new things. Though they may have the right safety equipment for tandem, but their skill set is not up to the level just yet.

Group C is for the new guys. They may still be learning about their cars, the track, etc. This is where everyone starts. There’s nothing wrong with being in Group C – we were all there. These are the guys who are working to link the course and beginning to understand what the right line is. They are figuring out what they need to do in the car to make a good run.
