Dome Motorsport ended the Pirelli GT4 America season with victories in two classes at Indianapolis Motor Speedway on October 11, 2026. Mercedes-AMG highlighted the breakthrough in an October 15 customer-racing recap, rather than announcing a new race result that day.

Two entries, two class victories

Allen Patten and Marc Miller won Pro-Am in the No. 39 Mercedes-AMG GT4. Laura Hayes took the Am victory in Dome’s No. 37 car. Mercedes says these were the second-year team’s first wins in the series.

The organizer’s October 11 report places Patten’s decisive pass for the Pro-Am lead four minutes from the finish. Its Am-class account confirms Hayes’ win while a separate fight for championship points unfolded behind her.

Mercedes says officials permitted Hayes to race alone after co-driver Eddie Killeen became ill. Her pit stop was lengthened to account for the difference from two-driver entries. The manufacturer also records a first Pro-Am podium for Off-Leash Motorsports’ Kevin Clifford and Harry Gottsacker on October 10.

Race wins are not season championships

The organizer names Sam Craven and Kenton Koch as Pro-Am champions, Frankie Muniz and Tyler Stone as Am champions, and Luca Mars and Spencer Pumpelly as Silver champions. Mars and Pumpelly’s RS1 title margin was one point despite retirement from the finale.

The official event page lists the No. 68 RAFA Toyota first overall, the No. 7 ACI Porsche second and Dome’s No. 39 third. Dome’s two trophies therefore should not be described as two overall race wins.

For readers following multiple sports-car championships, the distinction is important: a class result, an overall finish and a season title answer different questions. Reporting them separately preserves the significance of Dome’s breakthrough without displacing the championship winners.

This was the October 8–11 Indianapolis meeting, not the Barcelona WEC weekend. For that separate series, see our Genesis Hypercar qualifying report.
