Put caster wheels under your sim racing cockpit if you need to move it for cleaning, storage or a room that also serves another purpose. Skip them if the rig stays in one spot, because a frame that stands flat on the floor always feels the most planted. The best of both is a metal caster set that rolls the rig away and then stands firm again.
Caster wheels are small swivelling wheels that you bolt under the frame. They turn a heavy cockpit into something you push with one hand. The big question is what happens to stability when you race. Before we answer that, here is the SIMGASM Hobby cockpit in green in a short showcase without speech.
Why add caster wheels to a cockpit?
Caster wheels make a heavy rig mobile, and that solves real problems in a normal home.
A full cockpit with seat, wheelbase, pedals and monitors easily weighs more than you want to lift. Yet you still vacuum under it, move it for guests or push it into a corner after a session. With casters, that takes seconds. They help most in a shared living room, a bedroom setup or a small flat. Our guide on how much space you need for a sim racing cockpit shows why moving the rig often saves floor space.
Do caster wheels make a sim rig wobble?
Cheap plastic casters add play, but a solid metal set keeps the frame calm.
Where the wobble comes from
Wobble comes from two places: play in the wheel carrier and a soft running surface. Plastic wheels flex under load. Thin carriers twist when you brake hard. With a direct drive wheelbase, the rig then rocks a few millimetres at every kerb. You feel that as vague force feedback.
What a good caster set does differently
The SIMGASM Casterwheel Set has a load bearing construction made fully from metal. The wheels roll on a bearing supported mechanism, not a simple plastic hub. Each caster has a rubber wheel that rolls quietly, grips well and protects the floor. So the frame moves smoothly when you push it, and it stays put when you race.

Casters or rubber feet: which is better for you?
The right choice depends on how often you move the rig and how hard you brake.
Choose casters when
You move the rig at least once a week. You share the room. Or you race a belt driven wheel or a direct drive base up to a moderate torque level. Casters also work under SIMGASM free standing monitor stands and support leg sets, so the whole setup rolls together.
Choose a fixed floor contact when
The rig never moves. You run very firm load cell or hydraulic pedals. Or you plan motion, where every bit of play in the base matters. In that case, read how to stop a sim racing rig from sliding on your floor for the best ways to keep it planted.
Does the frame size change the answer?
Yes, because a deeper profile spreads braking forces better over the base.
The Hobby cockpit uses a 40 x 40 mm main profile and measures 500 x 1270 x 580 mm. It is compact and light enough that casters make a big difference in daily use. The Sport uses a 40 x 120 mm profile, measures 580 x 1320 x 720 mm and carries a rated braking load of 300 kg at the pedal deck. It is heavier, so moving it without wheels is harder, and its stiffer frame keeps things calm on casters too.

How do you fit caster wheels the right way?
A few simple steps make sure the rig rolls well and still stands level.
First, fit the casters to the lowest profiles of the frame, one at each corner. Then check with a spirit level that the rig stands straight. After that, tighten all T nuts again after your first race, because new mounts settle a little. Finally, push the rig into its racing spot and check that it does not roll when you brake.

Why metal matters for small parts
Small parts carry big loads in a cockpit, so the material choice counts.
SIMGASM founder Johan Akkerman worked as a technical specialist and workshop manager for brands such as Jaguar and Mercedes before he moved into sim racing. That background in materials and production methods shows in parts like these casters: metal where the load sits, rubber where the floor is. SIMGASM products carry a standard warranty of 2 years.

PC racers who roll the rig around also like a keyboard swivel mount or mouse tray on the frame, so nothing stays behind on a desk.
Questions and answers about caster wheels
These are the short answers racers look for before they put wheels under a rig.
Do caster wheels reduce force feedback detail?
Cheap plastic casters do, because they add play. A metal set with bearings and rubber wheels keeps the frame stable enough for normal use.
Do caster wheels damage wooden floors?
Rubber wheels are floor friendly and roll quietly. Hard plastic wheels leave more marks.
Do casters also fit a monitor stand?
Yes. The SIMGASM Casterwheel Set also fits free standing monitor stands and support leg sets.
Are casters a good idea with motion?
No. A motion system needs a fixed base, so take the casters off or use a separate motion setup.
