MECHANICSBURG, Pa. — The Williams Grove Speedway season opener presented by Hoosier will be the first Yellow Breeches 500 race of the year for the Lawrence Chevrolet 410 sprint cars coming up on April 7.
The event will also serve as the season debut of the HJ Towing & Recovery 358 sprint cars.
The 410 sprints will compete in the Yellow Breeches event, offering $500 to start the 25-lap main while also offering $5,000-to-win.
Timed practice laps will set the heat starting grids for the 410 sprints as will be the case in all Yellow Breeches races during the season.
The 358 sprint cars will compete in a 20-lap feature to begin their season.
The April 7 opener will be the latest at the track since 1979 when the first race of the year was won by Kramer Williamson on April 18.Â
Only once since then has the oval opened in April when Donnie Kreitz took a win on April 1, 1994. All other season lidlifters since 1979 have taken place in either February or March.Â

For drivers, the April 7 Yellow Breeches race will find only the new Hoosier D Series compound left rear tires and D15A and medium right rear tires permitted for use.Â
The same tires will again be mandated for the Tommy Classic on April 21.
