The Indianapolis 8 Hours weekend served as the final round for both the Intercontinental GT Challenge (IGTC) and GT World Challenge America powered by AWS. Lost underneath the main event was that Indianapolis also served as the final weekend for the 2026 SRO America programme.
There are five support series that make up the programme that also crowned their champions at the Racing Capitol of the World. Let’s take a look at who emerged victorious in the races and took home ultimate honors.
McLaren Trophy America
The start of the final round of McLaren Trophy America at Indianapolis on Friday
We begin with the final race in a tripleheader weekend for McLaren Trophy America. (To catch up with the first two races, click HERE.) This is the final race for the series in the SRO family before moving over to IMSA next season. James Li and Sam Neser took victory in Friday’s final race of the season. Behind them, third place was just enough for Patrick Liddy and Tanner Harvey. The Forte Racing duo, after extensive review, would be crowned Pro champions.
Over in the Am class, father and son duo James and Jenson Sofranos competed together for the first time. Following their first weekend, they may consider driving together more often. Fifth overall was good enough for class honors. Meanwhile, Cooper Broll had clinched the Am championship Wednesday after winning the Miami make-up round. Broll gave Forte two championships in the series and more impressive considering he drove the entire season solo.
Finally, Pro-Am would see their championship conclude at the green flag. With Oliver Webb taking the start, the title was clinched for he and Ryan James in the Greystone GT entry. In the race, it would be a victorious end to the season for Alexandra Hainer and Jesse Lazare. The Motorsport in Action team scored their first win of the season.
TC America
The tight and close racing of TC America at the Brickyard
Friday’s Race 1 saw a dramatic swing as points leader Andre Castro started from pole to lose the lead to teammate Justin Gravett. To make matters worse, his closest rival Brayden Arthur would pass Gravett for the lead on Lap 2 and would not relinquish the lead until the checkered flag. Meanwhile, Castro would fall back to fifth before regaining fourth, which is where he would finish. Arthur’s win would swing the championship advantage in his favor by five points over Castro. The Skip Barber Racing Acuras of Dean Landros and Logan Anderson would round out the podium.
Onto Saturday and a damp track would greet the field for the championship decider. Dean Landros started from pole, but was one of the few in the field that gambled and chose the slick tires hoping the track would quickly dry. By Turn 5, it looked as if his gamble would not pay off. Significantly, it would be Arthur would storm by and take the lead. Similarly to Friday, Arthur took the lead and never look back. Andre Castro and teammate Matan Rosenberg could not keep pace with the Canadian. Rosenberg would have to settle for second with Castro finishing third. For Arthur, his weekend sweep would earn him the 2026 TC America Championship by 15 points over Castro.
GT America
Peter Dempsey and Risi Competizione came to write their own headlines with the GT2 Maserati in GT America
With Memo Gidley clinching the championship at the previous weekend at Barber, the final weekend at Indianapolis was all for fun in GT America. Champion Gidley would start Race 1 from pole in his SKI Autosports Audi. But it would be Peter Dempsey starting twelfth in the Maserati GT2 that would quickly grab the headlines.
While Gidley led the race from pole, Dempsey would carve his way through the SRO3 field. By turn 1 on Lap 2, Dempsey would already be up to second. The champion would prove to be a little tougher. Dempsey would stay on the back of the Audi for the majority of the race. Eventually, with three minutes to go, Dempsey would find his way past the Audi. Dempsey would pilot the Risi Competizione prepared Maserati to the win, a first in GT America for a GT2-spec car.
Dempsey would make it a clean sweep, dominating Sunday’s Race 2. Nevertheless, it would not a trouble-free run as Dempsey would go off at Turn 7 on Lap 2, but would not lose the lead. After getting back on track, Dempsey would maintain his advantage up front. Dempsey would beat champion Gidley by 2.7 seconds with Ross Chouest rounding out the season with another podium.
Pirelli GT4 America
Tyler Gonzalez and Westin Workman were the class of the field all weekend
Race 1 on Saturday saw Westin Workman and Tyler Gonzalez score a crucial win to keep their Silver class championship hopes alive. The RAFA Racing Toyota Supra controlled the race throughout, eventually winning by three and a half seconds over a pair of McLarens. While Michael Cooper and Tony Gaples would win Pro-Am, Kenton Koch did just enough. His second-place class finish would secure the championship for co-driver Sam Craven with one race to go. In the Am class, Michael and Alex Garcia beat out Tyler Stone and Frankie Muniz to ensure the class championship would go down to the wire.
Race 2
Workman and Gonzalez’s chances to win the championship earn a massive boost when drama struck Luca Mars. Mars was spun by Werner Neugebauer in another RAFA Racing Supra, then colliding with Josh Green in the Random Vandals BMW. While Mars and Green were taken out, significantly the Advance Motorsport McLaren of Parker Delong was also taken out. With all three Silver class cars out of the race and Mars covering more distance, that would be the difference in the championship. As Workman and Gonzalez swept the race victories, the seventh place would be enough for Mars and Spencer Pumpelly to win the Silver class championship for RS1 by just one point.
Dome Motorsport had a banner day with victories in both Pro-Am and Am. Allen Patten chased down Matt Travis to deny Nolasport and get victory for he and Marc Miller. Over in Am, Laura Hayes drove solo and won decisively. Behind her, a late penalty to Michael Garcia with fifteen minutes left took he and his brother Alex out of championship contention. Meanwhile, Frankie Muniz would pass Jake Walker Jr. and pull away. Second place in class for Muniz and Tyler Stone would make them Am class champions.
Finally, in a class act, Sam Craven asked if his four points from Road America could be forfeited so he could share the Pro-Am with his season-long co-driver Kenton Koch. Koch had to miss the Road America round for the birth of his daughter. SRO obliged and accepted the request. Officially, Koch and Craven are your Pro-Am champions for Random Vandals.
Toyota GR Cup North America
Finally, we have our two-horse race in Toyota GR Cup North America. Spike Kohlbecker held advantage over Jeremy Fletcher going into Indianapolis. Kohlbecker led the field from pole in Race 1, but not for long. Parker Delong would take the lead and open the door for Fletcher to get head of Kohlbecker. After a festive mid-race battle, Kohlbecker would emerge ahead of Fletcher and Will Robusto among others. Delong would pull away and despite Kohlbecker closing in and giving him issues late, Delong held on for his first GR Cup win.
Race 2
Delong would take pole for the title decider with Fletcher starting ahead of Kohlbecker and needing help. On the start, Fletcher and Kohlbecker would overtake Delong for first and second respectively. The contenders would give each other no room and it almost cost them both. On Lap 6, Kohlbecker tapped Fletcher on the frontstretch – almost into a spin – but heads up driving from Fletcher and both continued on. Later on that lap, Patrick Brunson had a heavy crash exiting Turn 11 causing a yellow.
After a lengthy yellow for clean-up, drama on the restart as Kohlbecker would lose the lead and then an excursion through the grass would send him down further. Kohlbecker fell as far back as tenth and Fletcher would work his way back to the lead. But as the race came to its conclusion, numerous factors decided the championship. Firstly, Delong passed Fletcher to assume the lead on Lap 21. Secondly, Kohlbecker had worked his way back to seventh by this point. Thirdly, there were multiple five-second post race penalties. Among them were Delong, Fletcher and Kohlbecker. Finally, as all this was happening, a second yellow froze the field for good.
After all the penalties were tabulated, fourteen year-old Niko Colby who was third on the road inherited the win. Consequently, with both Fletcher and Kohlbecker failing to score due to the penalties issued, Spike Kohlbecker is the 2026 Toyota GR Cup North America champion.
Reset and Start Again
What a Sunday to conclude the SRO America season. Congratulations to all the champions on their well-earned and deserved accolades. The teams will now go into hibernation until Spring 2027. SRO America convenes again to kickoff the new season in April at Sonoma Raceway in California.
