“Should I put caster wheels on my sim rig?” is one of those questions that appears in almost every Trak Racer forum thread. Trak Racer sells caster wheel kits for many of their rigs, and the idea is tempting: roll the rig into place, race, then move it back.
The trade-off is simple: mobility can reduce stability if you don’t plan it properly. This guide explains how to choose between casters and fixed feet, and how to keep an aluminium rig stable either way.
Casters vs feet: the real differences
| What you want | Casters | Fixed feet |
|---|---|---|
| Move the rig often | ✅ | ❌ |
| Maximum braking stability | Depends on caster quality and locking | ✅ |
| Low noise and vibration transfer | Usually worse | Usually better |
| Leveling on uneven floors | Harder | ✅ |
When casters make sense on Trak Racer rigs
- You must move the rig for space reasons (shared room, small apartment)
- You have a smooth hard floor and high-quality locking casters
- You can accept slightly more vibration and noise
How to make a caster rig feel stable
1) Lock all wheels and test under braking
The “stability test” is simple: jump in, press the brake as hard as you ever will, and watch what moves. If the rig shifts or twists, you’re losing consistency.
2) Separate monitors from the rig if you use motion or tactile
A rig that moves on wheels plus triple monitors is a recipe for wobble. If you want monitors that stay stable, use a freestanding solution like the Apex freestanding triple monitor stand.
3) Use cable routing that tolerates movement
If the rig rolls, cables need slack and strain relief. Leave service loops and avoid hard bends in HDMI, DisplayPort, and USB cables.
Where SIMGASM fits into a “moveable rig” plan
If you want a clean rig you can still move, start with a cockpit that stays rigid and adjustable, then add mobility carefully. SIMGASM rigs are designed with usability in mind:
- Hobby racing simulator for a compact, affordable starter
- Club racing simulator for an 80×40 all-rounder
- Sport racing simulator for extra space and internal routing (clean builds, easy service)
- Pro racing simulator if you want maximum stiffness for strong DD and future motion
If you’re building in a small space, it’s worth talking to SIMGASM support and sales. The team responds fast and can help you choose a layout that stays stable while still fitting your room and budget.
Recommended SIMGASM gear: Club racing simulator, Sport racing simulator, Apex freestanding triple monitor stand, and Core Recline seat.

Floor types and what to expect
- Carpet: casters can feel “squishy”. Fixed feet often feel more direct for braking consistency.
- Laminate/wood: casters are convenient but can transmit noise. Consider vibration isolation if you race at night.
- Tile/concrete: very stable, but can amplify vibration. Keep cables and accessories tight.
Mobility is great — as long as your braking feel stays consistent. That’s the whole point of upgrading to a cockpit.
