We can’t let the weekend pass by without giving a special shout-out to the Super Modified teams putting on a show at the Diamond Cup! 🏁🔥

A huge shout-out to NatAttack for those incredible qualifying laps! What a performance! 👏💪

And a big shout-out to Natalie Waters, Nate Little, Mike, and Matt Elliott MMFE! We love watching these cars and drivers push the limits and put on an incredible show for the fans.

Good luck to all the Super Modified teams this weekend. Keep digging, keep chasing speed, and most importantly, stay safe out there! 🏆🏁

The Diamond Cup is here, and we’re proud to have FOUR Big Willie Chassis hitting the track this weekend! 🏁🔥

Good luck to all of the drivers, crews, and families representing the Big Willie family. We know the hard work, late nights, and dedication it takes to get to race day, and we couldn’t be more excited to see what this weekend brings.

Race hard, stay safe, and most importantly, have fun. We’ll be cheering for all of you as you chase that Diamond Cup glory! 💎🏆

We rolled into Meridian Speedway yesterday with two challenges laid down during our team meeting:

1️⃣ Have fun and do our thing.
2️⃣ Lay down the fastest lap we’ve ever run at Meridian Speedway.

William Ginn looked at those challenges and said, “Challenge accepted.”

After a solid practice day yesterday, it was time to qualify this afternoon. When the helmet went on, W***y was ready to show off—and show off he did!

🏁 P4 Qualifying
⏱️ 11.391 seconds

That makes it the fastest lap W***y has ever run at Meridian Speedway!

We’ve still got work to do, but what an awesome weekend it’s been so far. Nothing beats spending time with friends, family, and fans who come out to cheer us on, celebrate with us, and support us while we all roast in the Idaho sunshine. ☀️😅

The car is fast, the team is having fun, and we’re just getting started.

Next up: Heat races! 👊🏁

While the race cars are out making laps, Irwin is out here living his best life. 😴🐾

Apparently, the sound of sprint cars roaring around the track is the perfect lullaby. Who needs white noise when you’ve got race engines?

Practice is in full swing, and our favorite shop dog is catching up on some much-needed beauty sleep. Wake him up when it’s time for treats… or victory lane. 🏁❤️

We had a solid practice day yesterday and got plenty of laps under our belts! The car felt good, the team worked hard, and we’re ready to kick off Day 1 today.

If you’re looking for something to do, come join us at Meridian Speedway and cheer on the #61 Big Willie Chassis team! We’re excited to get back on track and see what the weekend has in store.

See you at the races! 🏁🏎️

Well… we let the weather fool us last weekend. 🌧️😔

After watching the forecast and trying to make the best decision, we made the call to stay home and ended up missing Round 2 of the Northwest Sprint Tour in Penticton. As it turns out, Mother Nature had other plans, and let’s just say… we won’t be making that mistake again! 🤦‍♀️

Lesson learned.

The good news? The car is loaded, the team is ready, and we’re headed to Meridian Speedway for the Diamond Cup! 🏁🔥

We’re excited to get back on track, put last weekend behind us, and see what we can do. Time to chase some laps, make some memories, and have some fun.

See you at Meridian! 👊

Good luck to all of the teams and drivers wheeling Big Willie Chassis in the second Race For The Million event at Owosso Speedway this Wednesday, June 3rd!

We’re incredibly proud to see so many Big Willie Chassis taking on some of the best competition. The hard work, late nights in the shop, long miles on the road, and dedication from every crew member are what make opportunities like this possible.

Now it’s time to strap in, hit your marks, and chase that checkered flag! We can’t wait to watch all of teams represent on one of the biggest stages in pavement sprint car racing.

Race hard, stay safe, and make us proud!

We wish we were there! We will be watching on FloRacing!

The shop is busy tonight as we get the #61 Big Willie Chassis prepped and ready to load up tomorrow for our trip to Penticton, BC! 🏁

The final checks are underway, bolts are being tightened, setup sheets are being reviewed, and the crew is making sure everything is ready for another weekend of racing.

This one is going to be a little different. Penticton Speedway will be a brand-new track for William Ginn and our entire crew. We don’t know exactly what to expect, but that’s part of the fun. New tracks mean new challenges, new lessons, and new opportunities to see what we’re made of.

We’re excited to hit the road, learn a new facility, and see how the #61 stacks up. The hard work in the shop happens long before the green flag drops, and tonight is all about making sure we’re ready when it does.

Penticton, here we come! 🇨🇦🔥
