No racing this week, but here’s the video from last weekend. Enjoy, like and share 😉👌🏼🏁

We rolled into Park Jefferson Speedway in Jefferson, South Dakota, for the final night of the Iron Cup, unloaded the #07 B-Mod, and were ready to GO!

Unfortunately, things didn’t exactly go according to plan.

In the heat race, a car spun right in front of us, and somehow WE ended up getting the black flag! That put us in the B-Main with one last chance to race our way into the feature.

And that’s where things got interesting! 🔥

After a couple
Weeks off we got back to racing this weekend and got our best finish of the season. Considering all the struggles and learning with this car this year this feels like a big win! Check it out, the video link is below.

This week we traveled to I-90 Speedway—and somehow managed to be fast and awful at the same time! Video link in comments.

We started the night third quick in hot laps, and the car showed plenty of speed. That put us on the outside of the front row for the heat race, but one huge driver mistake sent us spinning all by ourselves.
After rebuilding the side of the car, we made a few setup adjustments before the feature. Those changes paid off—the car was finally balanced, comfortable, and working well.
We started 14th and drove back to a 9th-place finish. The car had even more speed than the result showed, but the driver needed to do a better job behind the wheel.
The speed is there, the balance is getting closer, and now it’s time to put together a complete night!
Subscribe and follow along as we continue working to make this B-Mod faster every week.

Other than a little sheet metal from 1 of like 5 restarts and spinning all by my self in the heat and taking some damage from that, the car was good last night. Finally feeling like it should. Slick smooth track top to bottom 👌🏼

Video coming soon! 😎🏁
