The championship battles in Pirelli GT4 America are set to reach their conclusion at Indianapolis Motor Speedway, with just two rounds remaining and titles still up for grabs across all three classes.
After a season filled with momentum swings, breakthrough performances and championship-defining weekends, the field now heads to the Brickyard for the final two 60-minute sprint races of the year. While some championship leaders have built sizable advantages, others enter Indy with everything still to play for.
Silver Class
Luca Mars and Spencer Pumpelly have been the benchmark in the Silver class for much of the 2026 season, putting together one of the most dominant stretches of the year in their No. 028 RS1 Porsche.
The duo embarked on an impressive seven-race winning streak that began at Circuit of The Americas and continued through Road America. Their run came to an end at Barber Motorsports Park, where they failed to finish on the podium for the first time since the season opener event at Sonoma Raceway.
Despite that, Mars and Pumpelly have built a significant advantage at the top of the standings. The RS1 pairing enters the final two rounds with 243 points, holding a 35-point lead over RAFA Racing Team's Westin Workman and Tyler Gonzalez. That gap leaves Workman and Gonzalez with ground to make up at Indianapolis, but with two races still remaining, the Silver championship remains within reach.
In GT4 America, momentum can change quickly, and with two opportunities left to score points at the Brickyard, Mars and Pumpelly will look to close out their dominant campaign by securing the Silver title.
Pro-Am Class
The Pro-Am championship picture is a little more complicated, with Random Vandals Racing's Sam Craven and Kenton Koch having emerged as the frontrunners despite a midseason change to the lineup for one event at the return of the summer break.
Craven and Koch have shared the BMW for much of the season, but Koch missed the Road America event while welcoming his first child. Craven therefore competed with a different co-driver, Thomas Merrill, for those rounds, resulting in the two Random Vandals drivers carrying different point totals heading into the finale.
Craven currently leads the individual Pro-Am standings with 215 points, while Koch sits second with 211.
Behind them, Tony Gaples and Michael Cooper have put together an impressive run of their own. The duo enters Indianapolis with 174 points following back-to-back weekend sweeps at Road Atlanta and Road America.
Those weekends produced a pair of memorable milestones for the pairing, with Gaples becoming the driver with the most starts in SRO America history and Cooper becoming the driver with the most wins.
They will now face a significant points deficit in their bid for the championship, but with two rounds still remaining, the title will not be decided until the final checkered flag falls at Indianapolis.
Am Class
If there is one class where the championship battle is truly coming down to the wire, it is the Am class.
TechSport Racing's Frankie Muniz and Tyler Stone have surged into the championship lead during the second half of the season, putting together a string of strong results that has completely reshaped the title fight.
The duo began building momentum with a podium at Sonoma Raceway, followed that up with another podium at Road Atlanta and then delivered a breakthrough weekend at Road America, sweeping both races.
Barber Motorsports Park provided another victory in Race 2, pushing Muniz and Stone to 168 points and the top spot in the Am standings, but their advantage is as slim as it gets.
James Clay and James Walker Jr. sit just one point behind with 167 points for BimmerWorld. Their season has included a major points haul at Circuit of The Americas, where the three-hour Lone Star Enduro awarded double points, followed by a victory at Sebring and three consecutive runner-up finishes.
However, the BimmerWorld pairing has been unable to add a podium finish in the last two events at Road America and Barber Motorsports Park, allowing Muniz and Stone to close the gap and ultimately move into the championship lead.
Now, with only two races remaining, a single point separates the two title contenders. Every position at Indianapolis could prove critical in determining who leaves the Brickyard as the 2026 Am class champions.
