3S Challenge

Holley LS Fest Texas 3S Challenge

3S Challenge stands for Speed, Stop, & Steering. It 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 setup, and brakes along with driver skill and focus will be the keys to fast times. The Baer Brakes 3S Challenge will be fun for both participants and spectators alike. It will be open to all participants who are registered for autocross.



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. The 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. In order to earn a timed run, each segment of the run must be clean.
