Built by a racing driver, not a brand
Julien Raidelet
I design the tools I need to drive, and that other racing drivers can use too.
HSIMRACING is the direct result of my journey, my frustrations, and my obsession with real feeling in simulation.
What I do exists today because, at one precise moment, I could not find on the market what I needed to progress.
Trained on track, not on screen
Before simulators, there was real competition. Cycling (French F.F.C.), then karting (Rotax DD2). Disciplines where body, mechanics, and mind are linked. Where you learn early that details decide performance:
- Tire pressure slightly off
- Braking a touch off balance
- A rushed camber setup
In karting, I learned to tinker, repair, understand. To build with few means, but guided by the engineer of the DD2 European champion team of the time.
This period shaped my way of thinking: practical, solution-oriented, always focused on efficiency in real conditions.
Driving with the body, not just the head
What interests me is not the accumulation of features, but the quality of truly useful information sent to the driver.
Flow. Feeling. Fatigue. Dexterity. Heat. Stress management. Gesture repetition. Muscle memory.
Anything that disturbs the driver's physical balance reduces performance. Anything that strengthens it becomes a legitimate tool.
This logic guides all my technical choices.
Nothing on the market. So I created.
When I turned to racing simulation, I realized how little attention was given to the real sensations of driving. There were few options for those who wanted to customize, experiment, and push the limits. Most products felt more like toys than true tools.
So I started as I always have: testing, modifying, building.
From 2013, I built extreme installations: triple projectors, wood structures, homemade systems. Technology changes, but the philosophy stays the same: maximize coherence between body, machine, and perceived information.
Pioneer of immersion since 2013. See for yourself.
⚠️ Warning: Loud music at start
Each HSIMRACING product was born from a real problem in session.
Excessive heat.
Loss of concentration.
Imprecise gestures.
Mental fatigue.
I design nothing that I have not personally faced while driving.
A workshop, not a showroom
I do not work in a glass office. I work in a workshop. A living space, sometimes messy, where we test more than we tidy. The products are precise, finished, demanding.
Disorder belongs to the process. Precision belongs to the result.
Everything is designed, assembled, and tested with the same demand: last over time, not just impress in a photo.
No marketing, just direct
No marketing team. No prepared speech. No empty promises.
When you buy an HSIMRACING product, you speak directly with the person who designed it.
Some systems have found their place in environments I did not expect: professional installations, private showrooms, extreme simulators.
I do not chase logos. I solve problems.
My clients speak better than me:
Why I do this
HSIMRACING exists because I refuse to let sim racing become a simple mainstream product; stripped of its passion and authenticity, closed to creativity, devoid of real engineering, reduced to nothing more than flashy hardware or casual console gaming.
What interests me are the drivers who seek:
- to understand
- to feel
- to customize
- to go further
For pleasure. For immersion. For racing.
Not to kill time. To really race.
Stop playing. Start driving.
Behind the workshop
No project of this size holds without human support. When the body gives up. When fatigue sets in. When doubt blocks momentum. There is a presence that allows to start again. The one who is there, every day. Constant. Essential. The invisible engine. Love in daily life.
HSIMRACING is a personal project. But it is never built alone.
