Is a Sim Rig Enclosure Worth It? My Honest Immersion Test (Roof + Ambient Lighting)

By /

I recently built a full enclosure for my sim racing rig.

PVC frame. Blackout curtains. Foam boards. Ambient lighting. The whole deal.

The goal?

Increase immersion.

After building the roof for my sim, I noticed I was still about 10 inches short of fully blocking out my peripheral distractions. I could still see the edge of my desk. Ambient light from the workbench. And on the right side? A full window letting in outside light.

So I decided to run an experiment:

Does enclosing your sim rig actually increase immersion — or is it just a cool-looking upgrade?

Let’s break it down.

Why I Built the Enclosure

After installing the roof (wrapped in carbon fiber vinyl), I immediately noticed something:

The roof made a huge difference in immersion.

But I could still see light leaking in from the sides. That slight peripheral distraction was enough to pull me out of the “in-car” feeling.

At the same time, I went down the ambient lighting rabbit hole.

Watching other creators run dynamic lighting — headlights flashing across walls, lightning effects, track transitions — I thought:

“Okay… I need that.”

So I built a prototype enclosure to test two things:

  1. Would blocking side light improve immersion?
  2. Would ambient lighting inside an enclosure amplify realism?

How I Built the Sim Rig Enclosure

This was never meant to be permanent.

I built it as a proof of concept.

Materials Used:

  • PVC pipe framing
  • Blackout curtains (hung with D-rings)
  • Foam board panels
  • Ambient ring lights
  • Carbon fiber vinyl-wrapped roof

Total Cost:

Approximately $200

And honestly… PVC is not as cheap as you think once you start making multiple Home Depot trips.

The enclosure sits about chest high and wraps around the sides and back. The curtains slide open and closed easily, which made it practical for testing.

The roof also served as a mounting point for the ambient lighting.

What Actually Made the Biggest Difference

Here’s the surprising part:

The roof alone made more impact than the full enclosure.

When I added:

  • Reflective carbon fiber vinyl
  • Foam boards lining the bottom of the rig
  • Light control above eye level

The immersion increase was significant.

But enclosing the entire rig?

Not nearly as impactful.

The Pros of a Sim Rig Enclosure

Let’s be fair — there are benefits.

1. Light Control (If You Have Backlighting)

If you have:

  • A window behind you
  • A spotlight in the room
  • Sunrise/sunset glare hitting your screens

An enclosure absolutely helps.

During my POV test, leaving a light source behind me made the difference much more noticeable. So if you’re fighting room lighting, this could matter more for you than it did for me.

2. Cleaner Streaming Background

For Twitch and YouTube:

  • No visible background clutter
  • No wires
  • No room distractions
  • No fish mounts or decor behind me

It creates a controlled visual environment.

3. Slight Ambient Light Enhancement

The ambient lights pop more in a darker enclosed space.

But here’s the key:

You don’t need a full enclosure for that.

You just need a dark room.

The Cons (And Why I Wouldn’t Do It Again)

Now the honest part.

1. Heat

This was the biggest downside.

The enclosure traps heat — especially with a roof installed.

During longer sessions, it gets noticeably hotter.

2. Harder to Get In and Out

You literally have to crawl into the rig.

That gets old quickly.

3. Cost vs Value

For $200–$300, you could buy:

  • A Buttkicker
  • Higher-end ambient lighting
  • A better custom roof
  • Additional tactile feedback upgrades

Dollar per immersion?

The enclosure loses.

The Real MVP: Foam Board Panels

Here’s the budget winner:

Foam boards.

For about $30 total, lining the bottom of the rig:

  • Blocks RGB glow from the PC
  • Hides messy wiring
  • Eliminates floor distractions
  • Improves visual focus

They’re not glamorous.

But they work.

And you can remove them instantly when needed.

From a cost-efficiency standpoint, this is the best immersion-per-dollar upgrade I’ve tested.

My Final Verdict: Is It Worth It?

Short answer:

No — unless you have major light problems in your room.

Did it increase immersion?

Yes.

Was it dramatic?

No.

Do the downsides outweigh the benefits?

For me, absolutely.

If I were starting over with a $300 budget, I would:

  1. Build a better roof
  2. Improve tactile feedback
  3. Upgrade lighting
  4. Add airflow (before enclosing anything)

What I’m Doing Next

Instead of keeping the enclosure, I’m likely going to:

  • Build a refined roof design
  • Possibly install a simple curtain hanger behind the rig
  • Consider a green screen for content flexibility
  • Focus on airflow and comfort

Immersion matters.

But comfort matters more — especially during long GT3 and GT4 sessions.

The Bigger Takeaway

This is what I love about sim racing:

It’s like running at-home science experiments.

You tweak.
You test.
You compare.
You optimize.

Sometimes the flashy upgrade isn’t the one that actually delivers the best ROI.

If you’re considering enclosing your rig, I hope this saves you time and money.

And as always —

I’ll see you on the grid.
