Quick answer
If you need to move your rig regularly, go with caster wheels. If your floor is uneven and you want rock-solid stability, choose levelling legs.
Mobility versus stability
The main tradeoff is simple: caster wheels let you roll your sim rig across the room, while levelling legs lock it in place on uneven floors. There is no one-size-fits-all answer—it depends on whether you prioritize ease of movement or maximum rigidity.
Caster wheels add height and can introduce slight flex if the locking brake isn't engaged. Levelling legs sit lower and distribute weight directly into the floor, which helps reduce cockpit movement under heavy braking.
Floor protection and noise
Both options protect your floor, but in different ways. The rubber feet on levelling legs grip the surface and dampen vibration, while caster wheels roll without scratching—provided you use the brake to stop unwanted movement.
If your rig is on carpet, caster wheels may sink or roll unevenly. Levelling legs with wide rubber feet are usually a better choice for carpeted rooms.
Verdicts
- Claim: Caster wheels make your rig unstable: Verdict: Partly true. Caster wheels with a brake can be locked to prevent rolling, but they add height and may introduce slight flex compared to levelling legs. For most sim racing, the difference is negligible if the brake is engaged. If you drive with very high force feedback, test the rig after installing caster wheels to ensure the brake holds firm.
- Claim: Levelling legs are only for uneven floors: Verdict: False. Levelling legs also reduce vibration transfer and keep the rig from shifting on smooth floors. They are a solid choice even on level surfaces if you never need to move the cockpit.
- Claim: You can use both on the same rig: Verdict: Not easily. The mounting points are the same, so you must choose one set of feet. Switching between them requires unbolting and rebolting, which is not practical for frequent changes. Decide based on your primary need—mobility or stability—before buying.
