Vehicle Classing:
- It is a driver’s responsibility to class their car as accurately as possible BEFORE the event. The most up-to-date classing info is available here (see the Time Trial guide at https://timetrials.scca.com/pages/classmycar)
- Classes:
  - Cars are classed according to each vehicle's modifications and relative power. Milwaukee Region SCCA uses most of the same categories as SCCA Time Trials -- Sport, Tuner, Max, and Unlimited.
  - Not sure how to class your car? If your car is not listed in any category, please contact the National office using the "Class My Car" link and ask them to class it. If your car IS listed, but you’re not quite sure which category it fits, please contact the registration team – before 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 allows only minimal modifications; click HERE for the full Sport Category guidelines. Sport Category 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 is a restricted ruleset. If a modification is not specifically authorized in the Rules, it is not allowed. (If it doesn't say you can, you can’t.)
    - Tuner Category includes allowances for some bolt-on modifications for tuning and adjustment. Click HERE for the full Tuner Category guidelines. Tuner Category is also intended for street-driven vehicles with a treadwear rating for 200 or higher, 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. Tuner Category is a restricted ruleset. If a modification is not specifically authorized in the Rules, it is not allowed. (If it doesn't say you can, you can’t.)
    - 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. Max Category is a restricted ruleset. If a modification is not specifically authorized in the Rules, it is not allowed. (If it doesn't say you can, you can’t.)
    - 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).Click HERE for the full Unlimited Category guidelines. Remember that ANY car running on sub-200 treadwear or race tires must be classed in Unlimited.

  - The Vehicle and Driver Equipment Safety Rules are as follows, with descriptions of each level below:

Sport, Tuner and Max categories must meet Safety Level 1.
- Production vehicles prepped within Sport Category allowances on aftermarket (non-OE) D.O.T. approved tires with a UTQG rating of 100-199 may meet Safety Level 1 and will be classed in Unlimited Category.

Vehicle Notes:

Vehicle Eligibility: SCCA CenDiv Time Trials are typically open to four-wheel vehicles that are street-legal, -licensed, and -insured, have completed the vehicle self-tech BEFORE the event, and pass the safety-equipment inspection at the track. Such vehicles must
- meet all of the Safety Level 1 Standards;
- be properly muffled;
- not have a high center of gravity:
  - potentially unstable vehicles with a high center of gravity – determined by whether they are wider than they are tall – are excluded from SCCA Time Trials.
  - Width is the average track width of the vehicle (measured from center of tire tread to center of tire tread on BOTH axles), and height is measured from the ground to the highest point. Extra caution should be exercised with non-traditional vehicles (e.g., trucks using racing slicks or tires with less than 200 tread wear rating.)
  - extra caution should be exercised with non-traditional vehicles (e.g., trucks using racing slicks or tires with less than 200 tread wear rating.)
Safety Level 1 Standards: The full guidelines are available HERE and cover the minimum standards for
- seats and seat belts;
- interior;
- brakes;
- tires and wheels;
- suspension and steering;
- engine and drivetrain;
- roll bars (if required and/or present);
- glass and mirrors;
- recording devices.

The SCCA Milwaukee Region reserves the right to exclude vehicles that do not meet the safety guidelines or general spirit of the SCCA Experiential Program.
Convertibles:
- 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, Safety Standard Level 1 requires the vehicle to meet 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 Time Trials Safety Level 2 standards for material and construction found at timetrials.scca.com.
  - 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.
  - 4. Factory Hard Tops: Convertible vehicles with a removable factory hardtop (e.g., a bolt-on) must now meet the requirements for convertibles.
  - 5. Retractable Hard Tops: Any retractable hardtop vehicle that has its B-Pillar move is considered a convertible and must meet any and all Safety Level requirements for both Time Trials and Track Days.
