TMI Products' TRIM Awards Put Custom Interiors Under the Spotlight at SEMA

Most custom builds get judged on the parts people see first: paint depth, stance, and the sound of the exhaust. The inside of the car gets less attention, even though it's the part every owner touches on every drive. The TMI Products 5th Annual 2026 TRIM Awards are built around that gap, and the competition's return to the SEMA Show in Las Vegas puts upholstery and design work in front of the same crowds that usually gather around engine displays.

Where and when the judging happens

The Corona, California, interior manufacturer will hold the trophy ceremony on Wednesday, November 4, 2026, at 11:30 a.m. PST. It takes place in Central Hall at booth 24477. Registered SEMA builds are inspected across 10 categories, and the ceremony is the moment the results go public for the show crowd.

Six judges will do the inspecting: Kevin Oeste, Sean Holman, Sara Morosan, Theresa Contreras, Marcel Venable, and Jason Mulligan. Their scoring covers the work you'd expect from a serious trim shop: seam alignment, pattern placement, stitch consistency, and how well colors and materials match across the cabin.

Open divisions change the picture

Not every class is a sales contest for one brand. Several categories require TMI seats or full TMI cabin packages, which makes sense for a manufacturer running its own awards. The open divisions are different. They accept any custom car, truck, SUV, or wagon, regardless of what's inside it.

That structure matters more than it first appears. The past four Best of Show champions were built with interiors from other manufacturers, so the judging has rewarded execution rather than logo recognition. For a builder weighing whether to enter, that's the practical takeaway: a shop that does clean, well-matched work doesn't need to be running one particular brand of seat to be competitive.

TMI Products Marketing Director Ross Berlanga framed the philosophy plainly: "The TRIM Awards are about recognizing exceptional interiors, regardless of brand." It's a sensible position for a company that wants the contest to be taken seriously by the wider custom community, not just its own customer base.

What winners actually take home

The prizes start with a custom Mothers Polish detail bag and gift certificates, which is the kind of reward that's useful in a shop. The more significant benefit is exposure. Every category winner is automatically considered for the Barrett-Jackson Cup at WestWorld of Scottsdale, running January 23-31, 2027. Barrett-Jackson is one of the best-known collector car auction events in the United States, so consideration there puts an interior-focused build in front of a very different audience than a typical show floor.

Berlanga pointed to how the contest has grown, saying, "The creativity, innovation, and attention to detail showcased by today's builders continues to raise the bar, and we're excited to honor the individuals and teams whose work inspires the entire automotive community." That raising of the bar is worth watching. As more entries come in with higher-end interiors, the margins between finalists tend to narrow to details like panel fit and pattern matching, which is exactly where experienced upholsterers earn their reputations.

Why interiors deserve the attention

Anyone who has fought hog rings onto a seat frame or tried to lay carpet flat over a transmission tunnel knows how quickly sloppy upholstery undermines an otherwise excellent build. A bad seat cover or a wavy headliner shows up on every drive, in every photo taken inside the car, and in every conversation the owner has with a passenger. Engine work can be hidden under a hood. The cabin can't.

That's the case the TRIM Awards are making. Shops that spend months on suspension geometry and engine bay plumbing often treat the interior as the final step, and the judging puts that final step on equal footing. The driver's seat deserves the same care as the powertrain, and a contest that scores it directly gives builders a reason to prioritize it.

If you're following the custom scene, watch the Central Hall ceremony in November and the Barrett-Jackson consideration in January. Those two moments will show whether interior craft is becoming a headline category in its own right, or whether it stays the quiet part of the build that only other builders notice. My read is that the open-division format gives it a fair shot at the first outcome.
