Do me a favor and like this post…
This week we rolled into the track with one goal: test a major setup change we've been wanting to try, and finally did.

Before unloading, we made one of the biggest adjustments we've tried in a long time—and from the first lap on the track, the car felt completely different.

Some changes immediately made the car better. Others took some getting used to. Throughout the night we worked to understand what the car wanted, how it reacted in different track conditions, and whether this new setup is something we'll keep in our notebook going forward.

Join us for another night of USRA B-Mod racing as we chase speed, learn more about our race car, and continue searching for the setup that can put us further up front.

We made a BIG setup change…. And it changed everything!

After a tough wreck a few weeks ago, we finally made our return to I-90 Speedway. We weren't exactly welcomed back with easy conditions either.
This track had everything—rough corners, muddy patches, slick racing grooves, and dry slick sections all on the same night. It made for one of the most challenging track surfaces we've raced on this season and forced us to make several setup changes throughout the night.
Some of those adjustments worked, and a few are definitely getting added to the notebook for future races. Early in the feature we got stuck on the bottom lane and probably stayed there longer than we should have, giving up several positions before finding our rhythm. Once things settled down, we raced our way through the field, battled in the middle of the pack, and brought the car home in one piece.
No torn-up equipment, valuable setup notes, and another night of learning—sometimes that's a win all by itself.

We headed back to I90 for the first
Time in a few weeks. We had every track condition all in one track… rough, slick, mud, dusty, and maybe 2 or 3 more I’m missing. Brought the car home in one piece, and working on getting the video together. Got some new camera cases so we tried some new on car angles. Video coming soon! 😎🏁Heather De Thury Aaron De Thury

New video alert!
Unfortunately, we weren't able to hit the track last week.
After damage from
A couple weeks ago, the repairs took longer than expected, forcing us to sit out race night and spend some extra time in the shop. In this video, we walk through everything that was damaged, what repairs have already been completed, and the final work needed to get our USRA B-Mod race-ready again.
While we'd rather be racing, sometimes the work in the shop is just as important as the laps on the track. Follow along as we get the car put back together, check over the rest of the chassis, and prepare for our next opportunity to race.
Will everything be ready in time for next weekend? Watch to the end and find out.

We needed a new 4 wheeler to get around at the track. So, we got the cheapest one we could find on marketplace. Video in the comments. 😎

Nice to pick up a heat race win again. I think we’ve found a little more speed we’ve been looking for with this car. Still more speed to find but we’re headed in the right direction finally.

Week 3 race recap!
Started off good, changes to the car were definitely noticeable in a good way. Car turns much better. Won the heat race from 3 rd. Started the feature 3 rd. Dropped to 5 th, it was a rough but slick track this week. Got turned around in a racing incident that ended our night. We will get it fixed and be back out.
VIDEO COMING SOON! Keep an eye out for the Tuesday video post!
