770 curbs. Every one set by hand.

Three miles of perfect racing surface, five inches deep, laid in three separate lifts — each one a different mix doing a different job.

Twelve inches into the soil at Turn 14. Drainage rebuilt at 4 and 6. All of it in a hot Willows summer, working a temperature window where 5 degrees the wrong way makes a whole load useless.

Most of what these crews built is already buried. That’s the job. Swipe through. Full story, link in bio.

“We’re completely blowing up and rebuilding the entire racetrack in 45 days… the way we did the curbing was driven really heavily by how is this going to drive or ride on a motorcycle”
