Justin Swanstrom’s “Prenup” Getting an All-Steel All-Glass Makeover?

Well folks, big things are brewing once again in Justin Swanstrom’s world, and if you're a fan of his infamous Lexus “Prenup,” you’re going to want to stick around for this one.

We’ve been following Prenup since it hit the scene back in 2021. From day one, this car wasn’t just another name on the No Prep Kings roster—it came out swinging with a ProCharged Hemi setup and immediately proved itself by winning two races in Season 4 of NPK. Pretty impressive for a fresh build, right?

But as with most fast cars, it hasn’t been all smooth sailing. After a crash the following year, Swanstrom gave Prenup a serious overhaul—first with a screw-blown Hemi, and later with a Nunan setup. Through it all, the car continued to evolve, and let’s be real—it never stopped being a threat on any surface.

Then came the radial scene.

That’s where Prenup really showed its teeth. Justin dove into some serious grudge and shootout racing with this beast and walked away with some major paydays—rumor has it one weekend alone brought in $250,000. Whether it’s on slicks, radials, or no prep, there’s no doubt Prenup has earned its rep as one of the nastiest No Time cars out there.

Now, with Justin launching Swanfest this October—a big deal in the small tire and grudge world—he’s got his eye on a growing class: All Steel, All Glass.

This class is catching fire across the U.S., and Justin wants in. Only problem? None of his current rides fit the bill. So, what’s the solution? Upgrade Prenup, of course.

Word is he’s planning to rework the front end and doors to meet all-steel, all-glass specs. Sure, it’ll make the car heavier, but in this class, that’s the name of the game. It’s a smart move too—with more races popping up in this category, having a car like Prenup in the mix could be a huge advantage.

Plus, with Justin’s newer NPK car no longer part of the No Prep Kings series and seemingly being set up for radials, it opens the door (pun intended) for Prenup to take on a new role. This isn’t just about staying relevant—it’s about dominating across multiple platforms.

And let’s not forget: Prenup is the only car Justin has publicly said he’ll never sell. That says a lot. It’s clear this one’s special to him, and after everything it’s been through, it deserves a second—or maybe third—chapter.

Between Prenup, the Pro Mod, the now-radial setup for Outdated, and Todd Fon’s car, Swanstrom’s operation is looking as stacked as ever. It’s rare to see someone running four competitive cars across multiple formats and still finding success at every turn. But Justin’s doing it—and making it look easy.

We’re still disappointed that he didn’t get a contract for Speed Promotions this season, but if there’s one thing Swanstrom knows how to do, it’s keep moving forward. Whether it’s behind the wheel of a radial monster or a steel-bodied killer, the man stays in the winner’s circle.

So, will we see Prenup lighting the boards in Radial vs. the World or other big-time classes? We sure hope so.
