There's a moment in every race car build where a pile of parts stops being a pile of parts and starts being a car. We hit that moment last week with the #19. We've been calling him Ike.
Ike is our newest Spec Miata. An NA chassis, built ground-up, and he makes his debut at our next event. This is the story of what actually goes into a build like this — the parts, the choices, the long nights, and why we do it the hard way.

Why an NA, and why build it ourselves
The NA is the first-generation Miata — the pop-up headlight one. In Spec Miata terms, it's the lightweight. Around 2,100 pounds, a 1.6-liter engine, and a chassis people have been racing for decades.
Most people starting a fresh Spec Miata build today reach for the NB. It's the dominant chassis now, with a slightly wider track and a small aero edge. The advantage is real, but it's small. And the NA has one thing going for it that lines up perfectly with who we are: it's the most affordable way into the class.
That matters to us. We don't build show cars. We build cars that put real drivers on track without a six-figure budget. The NA does that. It's why we picked one for Ike.
We don't build show cars. We build cars that put real drivers on track without a six-figure budget.
Building it ourselves is the other half. When you build the car, you know every bolt on it. You know what's been torqued, what's been checked, and what's going to need attention in three weekends. A car you built is a car you trust. A car you bought is a car you're still learning.
The cage: where a street car becomes a race car
The single biggest job in any Spec Miata build is the roll cage. This is the line where a street car stops being a street car.
A proper Spec Miata cage isn't a bolt-in kit you slap together on a Saturday. It's welded into the chassis, tied to multiple mounting points, with NASCAR-style side-intrusion bars to protect the driver in a hit. Per builders like NASA Speed News, a good cage is fabricated around the driver — the harness bar gets placed at the right height with the driver actually sitting in the car.
That's the detail people miss. The cage isn't generic. It's built around the person who's going to race the car.

Once the cage is in, the interior strips out and the real race hardware goes in: a fixed-back race seat, camlock harnesses, a window net, a fire system, and a master cutoff switch. The floor and a bit of the transmission tunnel get modified, within the rules, so the seat mounts low and solid. None of it is glamorous. All of it keeps a driver safe.
This is also where our partners earn their spot. Every LFR driver gets fitted head-to-toe in K1 RaceGear — suit, gloves, shoes, helmet, and head-and-neck restraint. K1 came out of K1 Speed, the big indoor karting chain, because they couldn't find gear that was both pro-spec and affordable for the racers walking through their doors. That's our whole mission in one sponsor. Pro-level safety at a price a grassroots racer can actually swing. Ike's driver will be in K1 on debut day.
Suspension, brakes, and the parts that make it fast
Here's the fun part. The suspension is what makes a Spec Miata one of the best-handling cars in the world for the money.
For a competitive build, that means real shocks — we run Penske on our flagship #121 — plus sway bars, end links, and the right bushings to take the slop out of a 25-year-old chassis. Spec Miata is a tightly controlled class, so you're not chasing exotic parts. You're chasing perfect execution of a known recipe. Every bushing, every alignment number, every corner balance matters because everybody's running the same basic package.
Brakes get the same treatment. Fresh calipers, race pads, good rotors, stainless lines, and high-temp fluid that won't boil halfway through a session. Stock brake fluid does not survive a race weekend. That's not an opinion — it's the first thing that fails when you push a street car hard on track.
Add it all up and a well-sorted NA Spec Miata lands somewhere in the $12,000 to $15,000 range all-in, per builders tracked by Grassroots Motorsports. That's not pocket change. But against most ways into real wheel-to-wheel racing, it's a bargain. It's a big reason the class exists.
Why we name our cars
We name our cars because they're not just equipment to us. Ike is going to carry a driver. He's going to take hits, get fixed in the paddock, and hopefully cross a few finish lines up front.
That's the heart of what we do. We build affordable race cars so that the barrier to racing is belief, not money. Ike is the newest piece of that. He joins our 1999 flagship (#121) and our 1995 car (#2) — three cars, all pointed at the same goal: getting more drivers on track who were told racing wasn't for them.
If you're a young driver staring at all of this thinking it's out of reach, that's exactly the gap our Kart to Car program was built to close. We provide the car, the crew, the coaching, and the path. You bring the belief and the work. Cars like Ike are how a kid with talent and no budget actually ends up on a grid.
What's next for Ike
The build is in its final stretch. Ike debuts at our next event, and we'll have him at the SCCA race at High Plains Raceway over the July 4th weekend with a new renter in the seat — going for the win.
We'll also have a new face on the crew: Bill James, a professional Level 4 driving instructor, joining us to help our drivers pull more out of these cars. A built car is only half the equation. A coached driver is the other half. More on Bill soon.
For now, Ike is almost ready. New cage, fresh suspension, race brakes, a number on the door, and a driver who believes. That's a race car.
If watching a build like this makes you want one of these seats for yourself, apply to Kart to Car — that's the door in. And if budget is the wall standing in your way, our scholarship program exists for exactly that reason.
