3S Challenge

Holley introduced the 3S Challenge in 2013 which stands for Speed, Stop & Steering. The Baer/SuperChevy magazine 3S Challenge combines elements of autocross and speed-stop into a single event that will test the ultimate limits of car and driver. Car balance- power, suspension set-up and brakes, along with driver skill and focus will be the keys to fast times. The 3S Challenge will be fun for both participants and spectators alike. The 3S Challenge will be part of the Grand Champion competition and will be held in place of the autocross on Sunday. It will be open to all participants signed up for autocross.


2017 Rules:

The 3S Challenge is a competition featuring speed, stop and steering (3S).  The format will be a side-by-side low speed down and back course layout that will feature a 180-degree turnaround, slalom, and a stop box.  Course layout will be dependent on the available space.  Each “run” will be a total of left side course time added to right side course time, plus any accumulated penalties.  There will be a morning practice and qualifying session (competitors will get as many runs in the morning session as time allows) followed by a bracket single elimination session in the afternoon.  Cone penalties  (:02) will be assessed and a stop box penalty (:05) will be enforced.

  1. The registered owner must drive the vehicle for all events.
  2. All drivers will be required to sign a liability waiver. Passengers will not be allowed.
  3. A mandatory drivers meeting will be held prior to the first competition.
  4. All prize-eligible vehicles must represent a street capable vehicle with a strong resemblance to a current or former production model.  No purpose built race cars or kit cars will qualify for awards in the autocross or speed stop event.  The only open-wheeled vehicles allowed are ’34-and-older domestic vehicles and replicas thereof.

  8. Competitors must use a single set of tires for the entire event, no tire changing between events will be allowed.  Tires will be marked during tech.  Tire changes will be allowed in the event of a catastrophic failure, but replacements must be of the same manufacturer and model as those approved during tech inspection.
