Convertibles and Safety:
- It is highly recommended that all convertible vehicles be equipped with an aftermarket roll bar that meets or exceeds the standards set in the Time Trials Safety Standard Level 2 (see those standards here).
- However, minimum safety standard requires the vehicle meets at least one of the following criteria and is not subject to any of the listed exceptions:
  - 1. Convertible vehicles up to and including the 2005 model year must have rollover protection meeting one of the following criteria:
    - A. The vehicle is equipped with documented factory installed roll over protection. (Examples of manufacturer-documented roll over protection include hydroformed and reinforced a-pillars or windshield frame and factory installed roll bars and/or “pop-up” bars that are designated as roll over protection.)
    - B. The vehicle is equipped with a commercially produced roll bar or roll cage which is described by the manufacturer to provide track-appropriate rollover protection. (E.g., “style” bars are not acceptable.)
      - 1. Braces and portions of the main hoop subject to contact by the driver’s or passenger’s helmet, as seated normally and restrained by seatbelt and harness, must be padded with a non-resilient material such as Ethafoam® or Ensolite® or other similar material with a minimum thickness of 1/2 inch. Padding meeting SFI spec 45.1 or FIA 8857-2001 is strongly recommended.
    - C. The vehicle is equipped with a roll bar that meets the Safety Level 2 standards for material and construction.
  - 2. Convertible vehicles of the 2006 model year or later must have a roll bar that meets the Safety Level 2 standards for material and construction unless one of the following criteria is met.
    - A. The vehicle is equipped with documented factory-installed roll over protection or a commercially produced roll bar or roll cage which is described by the manufacturer to provide track-appropriate rollover protection.
    - B. The vehicle is six (6) cylinders, with the OE drivetrain and may only be naturally aspirated.
    - C. The vehicle is four (4) cylinders or less, with the OE drivetrain, including any forced-induction equipment.
    - Note: This means that for 2006+ vehicles, if the engine is not the original equipment model as delivered in that vehicle, aftermarket forced induction has been installed, or the vehicle has more than six (6) cylinders or six (6) cylinders and forced induction of any type, the vehicle must have aftermarket rollover protection or documented factory rollover protection.
  - 3. T-tops and targa top cars:
    T-top and targa top cars are not considered convertibles, and do not fall under the convertible requirements.
Time Trial Licenses:
- TT Licenses are not required for this event.
- Drivers can log TrackSprint experience toward qualifying for an SCCA Time Trials license.
- Be sure to let the Registrar know that you want a logbook when you come to the SCCA check-in table!
Run Groups:
- We typically have 3-4 run groups for TrackSprint: Advanced, Intermediate, and Novice. (We typically split the biggest group into an A group and a B group to minimize wait time between runs -- but this can shift depending on enrollment.)
- These run groups are based on the driver's skill and experience. You don't have to drive any faster than you feel comfortable, but comfort levels and speed tend to increase with experience, which is why we offer different run groups.
- Remember, TrackSprint means one car at a time with no passing, so choose the group that fits you best!
Vehicle Classing:
- Please do your best to class your car as accurately as possible before the event. The most up-to-date classing info is available here (see the Time Trial and TrackSprint guide at SCCA Class My Car)
- Not sure? Email us BEFORE the event and ask!
- Want to get out on track but don't want the pressure of competition? Select "Fun Run" as your vehicle class!
- Classes:
  - Cars are classed according to each vehicle's modifications and relative power. Chicago Region SCCA TrackSprint uses most of the same categories as SCCA Time Trials -- Sport, Tuner, Max, and Unlimited -- along with a non-competitive "Fun Run" option. Not sure how to class your car? Please select "NEED HELP" from the pull-down menu and/or contact the registration team -- in advance of the event, please -- and we'll do our best to get you sorted.
  - Click HERE for the full SCCA Time Trials National Classing guidelines -- including the "Class My Car" option if your car is not listed.
    - Sport Category, which ranges from Sport 1 (higher performance) to Sport 6 (more modest performance), is for daily-driven street cars on tires with a treadwear of 200 or higher. Sport Category allows only minimal modifications; click HERE for the full Sport Category guidelines.
    - Tuner Category is also intended for street-driven vehicles with a treadwear rating for 200 or higher, but here there are allowances for some bolt-on modifications for tuning and adjustment. Tuner Category ranges from Tuner 1 to Tuner 5, and there is room for your SCCA Solo (autocross) ST cars, too, as long as they run on TT legal tires. Click HERE for the full Tuner Category guidelines.
    - Max Category is where you find "Maximum" street cars: engine swaps, aftermarket or increased forced induction; suspension geometry changes; or even aftermarket wings and bodywork. Max Category ranges from Max 1 to Max 5, and this might be where you enter your approved Kit car; click HERE for the full Max Category guidelines.
    - Unlimited Category is for those production-based vehicles that are not street-going or on DOT tires with less than 200 treadwear ratings, or are on non-DOT, full racing tires. Unlimited is divided into Unlimited 1 (production silhouette, but over the displacement limits or under the weight limits for Unlimited 2) and Unlimited 2 (minimum of 1750 pounds with driver and maximum displacement of 3.0 liters). Remember that ANY car running on sub-200 treadwear or race tires must be entered in Unlimited AND meet the requirements for Safety Level 3 (very similar to road racing requirements for safety). Click HERE for the full Unlimited Category guidelines.
  - What if my vehicle isn't on the competition list? Use the "Class My Car" link, enter your vehicle's information / options / trim level, and SCCA National will review your info and get back to you! Any cars that have not been classed by the National Office before the event will be entered in Unlimited or Max
  - Fun Run: If you're not sure (or maybe just not saying) what's under the hood, or if you want to try the track without the pressure of competition, select "Fun Run" from the pull-down menu when it comes time to select your vehicle's class. Please note: Fun Run vehicles are not eligible for trophies.
Workers:
- To make the event run smoothly, we NEED workers, and we invite YOU to volunteer!
- Don't worry, all workers still get to drive!
- You will be assigned to work either the first or second half of the event, and you get to drive the other half of the event!
  - No Experience Needed (show up on time and we'll teach you everything you need to know):
    - Recorder -- works in the trailer with a radio and writes down finish #'s as called in from the track
    - Grid Assistants -- help get cars lined up, check wristbands and helmet straps, release cars from false grid to hot grid when notified, help announce grid calls
    - Finish Radio -- sit in your car just past the finish timers to record car #s and radio them to T&S)
  - Set-up and/or Take-down -- feather flags, timing lights, antennae for timing system, and so on.
  - Previous Experience and/or SCCA Credentials Needed
    - Timing & Scoring 1 -- must be fluent in Pronto timing software

      - Starter
      - Registration
  - Volunteers still get to drive! You'll work one half of the event and drive to your heart's content in the other half.
  - Note: If volunteering means that you drive more than the standard number of runs, only the "standard" number of runs will count toward your placement. For instance, if non-volunteers get five runs, only your first five runs will count toward your placement.
Drivers' Meeting:
- There will always be a mandatory drivers' meeting for all participants with in-depth instructions on flag rules, safety and track etiquette; this will take place at least 30 minutes before the course goes hot.
- Plan to allow 15-20 minutes to get through registration and prep your car before the meeting. Information given at the meeting is crucial to EVERYONE for a safe and smooth event.
- Any drivers not in attendance at the drivers' meeting will not be permitted to drive until they have met with the Classroom Instructor. No refunds, no exceptions.
Cancellation Policy:
- Please use MSR to cancel, or -- if something happens on the way to the event -- email/text the registrar to let us know. No charge for cancellations made through MSR, email, or phone more than three days before the event.
- Credit cards will not be charged until the day of the event.
- Cancellations made within 72 hours of the event will be held as a credit toward a future Chicago Region TrackSprint, Time Trial, or Track Event.
