The USAC AMSOIL Sprint Car National Championship will headline the 59th Avanti Windows & Doors Western World Championships at Central Arizona Raceway in Casa Grande, Arizona, scheduled for late October on the track’s 3/8‑mile dirt oval. Sources differ on the exact date — Release 1 lists October 24 and Release 2 lists October 23 — and organizers said the program will include Avanti‑branded CRA and Southwest sprint car divisions; both releases list Kirk Spridgeon as race director.

The two releases provide different on‑track schedules. Release 1 lists pits opening at 2:00 p.m. MST, gates at 3:00 p.m., a drivers’ meeting at 4:00 p.m. and hot laps at 5:00 p.m., while Release 2 lists pits opening at 2:00 p.m., gates at 4:00 p.m., a drivers’ meeting at 5:00 p.m. and hot laps at 6:00 p.m. Release 1 also specifies a mandatory driver radio frequency of 464.5500; that frequency does not appear in Release 2.

The releases also differ on competitive format and payout. Release 1 describes qualifying races with top‑five transfers, a multi‑segment Underwood Dash that pays $5,000 to the winner, a 12‑lap semi‑feature and a 35‑lap main for 24 starters, and lists the feature winner purse at $35,000 (second $5,000, third $3,000). Release 2 describes two‑lap qualifying with multi‑heat inversion formats, a 30‑lap feature and reports the feature winner would receive 70 USAC points and a $7,500 purse.

Ticketing, entry and broadcast details are consistent across the releases on the main items: general admission at the gate will be $40 for non‑reserved seating and $50 for reserved seating, with children 10 and under admitted free; entry fees are $30 for USAC members and $40 for non‑members, and drivers must be USAC members to earn points and contingency awards. Both releases state fans can watch on FloRacing, listen via the USAC app (via Mixlr), follow live timing on MyRacePass and Race Monitor, and get updates on USAC’s Facebook and X pages; Release 1 describes pit passes as being “priced by age group,” while Release 2 provides amounts of $45 for ages 13+ and $30 for ages 5–12. The principal inconsistencies to note are the exact event date, the on‑track start times and the competitive format/prize structure; consult Release 1 and Release 2 to confirm which schedule and payout details you should follow.
