Sam Mayer heads back to Chicago, Illinois for his second run at the Chicago Street Course on the heels of a top-10 finish at Nashville Superspeedway.
At this course last season, Mayer was on a fast track to the front until the rain delayed chaos subjected the young driver to an 18th-place effort.
The Franklin, Wis. native is no stranger to road courses as he scored three victories on tracks of this kind last season, including the first win of his NASCAR Xfinity career at his home track, Road America.
Mayer and JRM welcome new partner PCI to ride along side the No. 1 Chevrolet Camaro in the streets of Chicago.
Sam Mayer “I am for sure ready for a change of pace in tracks so I am pumped to get back to the Chicago Street Course. Last season at this course, it was hard to really get a feel for the track with all of the different weather hurdles we faced. Road courses have been really good to us in the past so I am looking forward to getting our left and right turns in at Chicago this weekend. Hopefully we get a chance to drive this No. 1 PCI Chevrolet into Victory Lane.”

In three starts on road courses thus far in 2024, Allgaier has amassed one top five and two top 10s, with a best finish of second coming at Portland last month.
Justin Allgaier “It’s great to be going back home to Illinois this weekend and to be racing in Chicago once again. The atmosphere last year was incredible and I think it will be even better this weekend. We had a really quick BRANDT Professional Agriculture Chevrolet here last year; we just didn’t get a chance to really show everything we had due to the weather. Hopefully this weekend the weather will stay clear and we can go out and put on a great show. I know that everyone on this No. 7 team is fired up, especially Jim (Pohlman, crew chief). It’s a home race for both of us and there’s nothing we would like more than to go to Victory Lane on Saturday.”
