There’s wheeling… and then there’s proving grounds.
These are the places that don’t care about your Instagram. They punish weak parts, expose bad setups, and reward builders who do it right the first time.
Here are 3 of the most iconic wheeling destinations—and the TMR-built rigs that get it done.
Utah — Slickrock & Precision
Baja, Mexico — Wide Open, Full Send
Rig: Vintage Ford Bronco
Owner: McCrossan Motorsports
Baja isn’t technical—it’s violent.
High-speed desert runs, endless whoops, and terrain that will shake your rig (and your confidence) to pieces. If your setup isn’t dialed, it won’t last long out here.
McCrossan Motorsports built this Bronco to survive—and thrive.
Running TMR:
This is the kind of environment where drivetrain support and suspension geometry aren’t “nice to have”—they’re the difference between finishing the run or getting towed home.
Backdoor, Johnson Valley — Straight Up Brutal
Rig: TMR Chassis
Owner: Steven Donovan
Backdoor is exactly what it sounds like—no easy way in, no easy way out.
Steep climbs, loose terrain, and zero room for error. This obstacle has humbled a lot of builds over the years.
Steven Donovan’s buggy doesn’t hesitate.
Running TMR:
Simple, strong, and built to take abuse. When your chassis is getting twisted and loaded from every angle, the small details matter.
Outer Limits, Johnson Valley — The Ultimate Test
Rig: TMR Chassis
Owner: Tim & Mike Rogers
Outer Limits isn’t just a trail—it’s a statement.
Massive rocks, brutal lines, and the kind of terrain that defines events like King of the Hammers. This is where real builds prove themselves.
And yeah—this one’s ours.
We don’t just make parts. We run them.
Running TMR:
This is what “race-proven” actually looks like. Not theory. Not marketing. Real abuse, real terrain, real results.
Built to Get You There!
Whether you’re bombing through Baja or crawling through Johnson Valley, the goal is the same:
Get out of the garage—and into it.
That’s what we build for.
TMR parts aren’t made to sit on a shelf. They’re made to take hits, keep moving, and bring you back for more.
