Horto and Juncos moved up to the Indy Lights series on a limited basis, while the team signed Connor De Phillippi, Bruno Palli, Martin Scuncio, and Diego Ferreira for their Star Mazda cars.

In 2013, the team would enter Ferreira and Scott Anderson in the series, now renamed the Pro Mazda Championship.

For 2014 the team entered four cars full-time in the series, driven by Spencer Pigot, Kyle Kaiser, Julia Ballario, and Jose Gutierrez.

[10] For 2015, Gutierrez returned to the team[11] along with new drivers Will Owen,[12] Timothé Buret[13] and Garett Grist, who moved over from Andretti Autosport.

[18] Pigot began the 2015 season with five straight podium appearances, including winning both races of the doubleheader at Barber Motorsports Park.

The facility, called the Juncos Technical Center, would cost three million dollars and be 41,000 square feet in size.

For the 2021 Indianapolis 500 Juncos leased their chassis to Paretta Autosport on behalf of Team Penske, with Simona De Silvestro driving the car.

De Silvestro managed to qualify the Juncos car in the last available spot for the Indianapolis 500 but ultimately retired from the race.

In a statement, the team said, "After a period of collaboration and shared goals, both parties have mutually decided to part ways, effective immediately.

[40] Following fan harassment and death threats towards Arrow McLaren driver Théo Pourchaire following an incident with Canapino at the Detroit Grand Prix and the ensuing social media furor and fallout, Arrow McLaren released a statement announcing the termination of their technical partnership with Juncos Hollinger Racing effective immediately.

[41] Canapino would soon after be withdrawn from competing at the 2024 XPEL Grand Prix of Road America, with the team stating he would be taking a "leave of absence"; he was replaced by Nolan Siegel at the event.
