Get on the grid with us.
Whether you're running our parts or want to help build the next ones, there's a way in below.
Development program
Test parts that don't exist yet. Prototypes ahead of release, in exchange for structured feedback from real track mileage — we ship parts to you, or you bring the car to us.
Racing program
Put us on a competitive car. Parts and technical support for cars running real championships, in exchange for prominent branding, results and content from every round.

Internships
Rolling intakeWe're specifically after a CAD automotive designer, a content creator and a graphic designer. Small team in the Netherlands, so you'll work on parts that actually ship.

Test parts that don't exist yet.
A small group of drivers who run our prototypes on track and tell us what's wrong with them before anyone else can buy them.
What this program is
The fastest way to find a weakness in a part is to put it on a car we didn't build, at a circuit we don't run, under a driver who doesn't care how long it took to design. Our own testing gets a part 90% of the way there — this program is how it gets the rest.
You get parts that aren't released yet, and in return you run them hard and tell us the truth about them. Some prototypes turn out great. Some come back and get redesigned. Both outcomes are useful, and honest criticism is worth more to us than praise.
We keep the group deliberately small — a handful of people we actually speak to every few weeks beats fifty names on a list.
Two ways to do it
Remote development
The car stays with you. We ship prototype parts to your door and you run them across your season.
- We send the parts — unreleased, at no cost or heavily discounted
- You fit them and run them hard over a season
- You send back data, lap times, photos and honest feedback
- You run our sticker on the car
- Works anywhere — you never have to travel to us
In-person development
You bring the car to us in Etten-Leur and leave it for a few weeks so we can develop directly on it.
- 3D scanning of your chassis for exact-fit parts
- Prototypes designed, printed and test-fitted on your car
- You get the finished parts fitted before it goes home
- Fastest route to parts for a chassis we don't cover yet
- Best for people within reasonable driving distance
How it works
- You apply with your car, and which of the two tracks suits you.
- We talk. A short call to check the fit both ways and agree what you'd be testing.
- Remote: parts ship to you. In-person: we book a window for the car to come to Etten-Leur.
- You run them across a season, back-to-back with the old setup where possible.
- You report back with lap times, data, photos and a plain verdict.
- We iterate. Your feedback goes into the production version — and you keep testing the next one.
- Pre-release parts, free or heavily discounted
- A direct line to the people who design them
- Real influence over the final product
- Scanning and test-fitting on your car (in-person track)
- 5+ track days or race events a year
- Fitting prototypes yourself or via a shop you trust
- Structured feedback — data, photos, honest verdicts
- Our sticker on the car, and discretion on unannounced parts

Be direct here — an honest "five days a year, but I log everything" beats an inflated CV.
We're looking for 5+ track days a year. Below that, the gallery is the better place to start — we'd still love to see your car.
Put us on a competitive car.
Parts and technical support for cars running real championships, in exchange for prominent branding and content from every round.
What this program is
Racing is where this company started and it's still the part we care most about. A car being pushed for a championship generates more useful information in one weekend than a road car does in a year — heat, kerbs, contact, sustained load, everything at once.
So we back a small number of competitive cars with parts and engineering time. In return we want to be visible: proper decal placement, photos and footage we can use, and a report after each round. It's a genuine two-way deal, not sponsorship in the charity sense.
This isn't only about exposure either. If your class rules allow it, we'll develop parts specifically for your chassis and setup, and you get them first.
How it works
- You send a proposal — series, class, confirmed rounds, car spec and the branding space you can offer.
- We review it against the season calendar and what we're developing for that chassis.
- We agree the deal in writing: parts, support level, livery position, content expectations.
- Parts and decals ship ahead of your first round.
- You race. After each round we want results, photos and footage.
- We build on it — setup input during the season, and co-developed parts if the rules allow.
- Parts support for the season
- Engineering and setup input
- Co-development on your chassis
- Coverage across our site and channels
- A confirmed season in a recognised series
- Prominent decal placement — not a small sticker
- Photos, footage and a report each round
- Honest feedback on how the parts performed
Apply for racing support
Tell us about the season, not just the car — the series, the rounds and the branding are what decide this.

Running our parts? Send us your photos. We feature customer cars across the site, product pages and socials — always credited.
What this program is
The best photos on our website aren't studio shots, they're customer cars being used properly. A splitter covered in rubber after a session says more than any render we could make.
So if you're running our parts, send us your photos. We use them on product pages, the gallery and our social channels, with your build spec listed and the photographer credited every time. Any chassis and any level — a clean street car is as welcome as a race car.
Nothing goes live without checking with you first, and you can ask us to take something down at any point.
How it works
- You send a link to your photos plus your build spec — two minutes, no account needed.
- We review submissions in batches and pick what fits what we're working on.
- We check with you before anything is published, and confirm the credit.
- It goes live on the gallery, a product page or our socials — tagged and credited.
- Your car featured on the site and socials
- Your full build spec published alongside
- Photographer credit on every placement
- A heads-up before anything is published
- Photos you own or have permission to share
- 3–10 shots, ideally 2000px+ on the long edge
- At least one ST part fitted
- The photographer's name for the credit
Submit your car
Send a link to your photos and your spec — Drive, Dropbox, WeTransfer or even an Instagram post is fine.
Work on parts that ship.
We're specifically looking for a CAD automotive designer, a content creator and a graphic designer — in a small team in the Netherlands, on parts that end up on real cars.
What this program is
We're a small company, which means an intern here isn't handed one narrow task. You'll see a part go from a sketch to CAD, to a prototype on the bench, to a car at Zandvoort, to a product page — and you'll have worked on more than one of those stages.
Track days and test sessions are part of the job, not a perk. School placements and self-initiated projects are both welcome.
Roles we're specifically looking for
CAD automotive designer
Turning ideas into manufacturable parts, and working on the CAD side of new prototypes.
- Part design in SolidWorks, Fusion 360 or similar
- Working from 3D scans of real chassis
- Design-for-manufacture on parts that get made
- Test-fitting your own work on the car
Content creator
Shooting and cutting the material that carries the brand — track days, workshop, product.
- Photo and video at test sessions and race weekends
- Editing for social, product pages and the blog
- Building out the development blog
- A portfolio full of real motorsport work
Graphic designer
The visual language across product pages, packaging, decals and campaigns.
- Product page and campaign graphics
- Decal and livery design
- Packaging and print
- Working directly on the webshop look and feel
How it works
- You apply with a CV or portfolio link and what you want to work on.
- We have a chat — informal, mostly about what interests you.
- We agree a project with a real deliverable, plus your dates and days per week.
- You start, embedded in the team rather than off to one side.
- You finish with something concrete: a part, a study, or a body of content that shipped.
- Real responsibility on parts that ship
- Exposure to the whole process, not one slice
- Track days and test sessions
- A portfolio piece you can actually show
- A CV or portfolio link
- Clear dates and days per week
- Own transport helps — we're not city-centre
- Willingness to get your hands dirty
