JR Motorsports Signs Another Driver for 2025

What’s Happening?

JR Motorsports has officially added to their 2025 NASCAR Xfinity Series lineup. The team announced Wednesday that Connor Mosack will return to JRM for October’s race at the Charlotte Roval.

• The 25-year-old will drive the team’s part-time No. 9 entry with sponsorship from JRM’s new partner, Registix. This is the only race announced for Mosack at JRM in 2025. Last season, Mosack made two starts with JRM in the then-part-time No. 88.
• Both of those starts were on road courses, with Moscak finishing 6th at the Chicago Street Circuit and 18th at the Roval. Moscak has 28 career Xfinity Series starts, making 24 with Sam Hunt Racing in 2023. He scored his career-best finish of 5th at Watkins Glen that season.
• This year, Mosack is making his full-time NASCAR National Series debut with McAnally-Hilgemann Racing in the Craftsman Truck Series. So far, Mosack has finished no better than 19th and sits 20th in points, the worst of his MHR teammates.
• Mosack will join Trackhouse Racing’s Shane van Gisbergen and Ross Chastain in part-time duties at JRM in 2025. The No. 9’s next race will be on May 31 at Nashville with Chastain, and SVG will make his JRM debut on June 14 in Mexico City.
