This is where the quickest cars at LS Fest Texas battle it out in a no prep competition on Texas Motor Speedway's pit road! Experience the ground-pounding action from some of the fastest LS and current generation LT-powered cars in The Lonestar State.

Each Participant Registration includes two (2) event passes - one for the Registered Participant (Driver) and one for a Crew Member OR Guest. All Crew Members MUST complete the waiver and present a state-issued ID at Check-In to receive Crew Member wristbands. Crew Member passes do NOT have a QR code. All Crew Member Passes are included with the Registered Participant's QR code (received after registration is completed) and all Crew Members must arrive with the Participant to receive credentials.

There will be a tire changer for those who end up needing to install a fresh pair to continue their donut pit, drifting, or drag racing efforts through the course of the weekend. Racers will be responsible for their old tires.

Important notice for all drag racers!
