A DIY sim racing cockpit is cheapest when you start from a bare frame and add your own seat, wheel and pedals, or when you cut aluminium profile to your own drawing. Check that the frame lists your wheel’s brand before you buy.
Once the rig is built, it also works as a base for headset racing, and our guide to the best vr games shows what to drive first.
How a cockpit build fits together
A cockpit is built in a fixed order, because every later part bolts to the one before it. One DIY cockpit seller sets out a five-step build order that works for profile and tube frames alike:
- Frame. Decide profile size, lengths and finish first. Everything else hangs from this.
- Wheel mount. Fit the deck or plate that carries your wheel base.
- Pedal mount. Add the plate or tray for the pedal set.
- Side mount. Add a shifter or handbrake position if you use one.
- Accessories. Finish with extras such as cable management or a monitor stand.
The practical consequence is that the frame decision locks in what fits. Pick the wheel and pedals you intend to own before you order the frame, and work from their mounting patterns rather than from the cockpit’s photographs.
Materials: aluminium profile or a ready-made frame
Aluminium profile gives the most freedom, because you choose every length. A ready-made frame saves cutting and measuring and is the safer first project.
Working with aluminium profile
The seller above uses 15 series profile, 1.5 in (38 mm) wide, which it describes as similar to 40 series. It offers silver anodised or scratch-resistant black powder-coat finishes. It does not sell loose extrusions; it sells assemblies such as shifter mounts, so a full custom frame may mean sourcing lengths elsewhere.
A builder in a GTPlanet forum thread lists the connection hardware as socket head bolts, M8x16 DIN 912. The same thread priced a 40x120mm profile kit at €441 and a 40×80 kit at €363, both including a wheel deck bracket, in a post dated Nov 2019. The builder also noted €30 shipping for profiles alone from a local dealer and that local dealers did not stock black profile. These are euro prices from an older post, so use them to see how the kit sizes compare, not as a UK quote.
Choosing between the two routes
Choose profile if you want to adjust the wheel deck and pedal tray later, or if you want a specific finish. Choose a ready-made frame if you want a working rig from one order. Profile also asks you to confirm finish and lengths before you pay, because the seller above does not accept returns for buyer’s regret and the client pays shipping.
UK parts and prices
The lowest UK entry is a frame-only listing; a cockpit with seat costs noticeably more. Wheel and pedals are a separate purchase unless a listing says otherwise, so the real total depends on the hardware you already own.
| Listing | Listed price | Listed as | Planning use |
|---|---|---|---|
| Adjustable steering wheel stand frame | £103.53 | Frame only; wheel, pedals and seat not included | Cheapest start if you already have a seat |
| Cockpit frame, no seat | £147.99 | Names Logitech G29, G920, G923, G27, G25 and Thrustmaster T248, T300 | Suits owners of one of those wheels |
| Foldable steel-frame cockpit | £173.99 | Names Logitech G29, G920, T300; listed size 70.9 x 33.1 x 37.4 in | Measure your room against this footprint first |
| Thermaltake GR300 | from £349.99 | Adjustable seat and frame, PC and console | Seat included, so no separate seat to buy |
| Frame (50mm round tube) with monitor stand and black seat | £362.51 | Fit for Logitech, Thrustmaster and Fanatec; no wheel or pedals included | The monitor stand matters only if you race on a screen |
| Thermaltake GR500 full-frame rig | from £599.99 | PC and console | Top of a budget range; consider only if the frame is the main spend |
| Anti-shift pedal clamp | £39.99 | Made for a Playseat Challenge cockpit | Relevant only if you own that seat |
Figures come from PriceSpy’s UK racing simulator cockpit listings, which show the lowest price or the marketplace price at the time of checking.
Read the table as a build menu rather than a price ladder. Buy a frame that matches your wheel, then add a seat only if the listing leaves it out. The listed Thermaltake GR300 price sits just below the frame with monitor stand and seat, so compare what is included before assuming the larger listing is better value.
Wheel and pedal compatibility with PC and console
Compatibility has two parts: whether the frame bolts to your hardware, and whether the hardware works on your platform. Frame listings only cover the first part.
Logitech G29 and similar wheels
The frame-only listing at £147.99 names the Logitech G29, G920, G923, G27 and G25, plus the Thrustmaster T248 and T300. The foldable steel listing names the G29, G920 and T300. If you own a G29, both are straightforward matches on paper, and the G29 is the safest wheel to design around because several listings name it.
Fanatec and other brands
The frame with monitor stand and black seat lists fit for Logitech, Thrustmaster and Fanatec. A Fanatec owner should confirm the mounting holes for their specific base against the frame’s wheel deck before ordering, because a general brand name in a title does not guarantee fit for every model.
PC versus console
The Thermaltake GR300 and GR500 listings state PC and console use. For the other frames, the platform depends on the wheel itself, so check the wheel maker’s compatibility page for the title and console you plan to use.
Fitting seat, wheel and pedals to the driver
Set the seat first, then move the pedals and wheel to suit it. If the frame is adjustable, the same rig can change as you or another driver uses it.
One foldable cockpit listing at £694.19 states it fits drivers from 150 to 220 cm tall and carries 90 kg, so use that as a reminder to check both height range and weight rating on any frame. A weight capacity is a ceiling set by the maker, not a comfortable target.
- Seat position. Sit in your normal driving posture and note where your back and hips rest before you tighten any bolts.
- Pedal reach. Place the pedal plate so a full press leaves your leg comfortable rather than locked straight.
- Wheel height and distance. Move the wheel deck until your shoulders and wrists feel relaxed with the wheel straight.
- Record the result. Write down each final position so you can rebuild it after any adjustment.
Adjustable slots or multiple bolt holes make this easy to do. A fixed frame leaves you to adapt to it instead.
Adapting the rig for VR racing
A headset replaces the screen, so a frame without a monitor stand can be all you need. Spend that saving on a better seat or pedal plate, since the rest of the build stays the same.
Screens are still an option. If you want to race on several displays instead, Triple Monitor Setup: How To Maximize Productivity And Gaming In 2026 – Viarama covers how to arrange them.

Frequently asked questions
Can I return parts from a custom DIY order?
It depends on the seller. The DIY cockpit seller mentioned above does not take returns for buyer’s regret, and the client pays shipping costs, so confirm finish and lengths before ordering.
Can I compare forum profile prices directly with UK frame prices?
No. The forum kit prices of €441 and €363 are in euros from a post dated Nov 2019 and include a wheel deck bracket, while the frames above are UK pound listings. Request a current UK quote with shipping before you decide.
Can a cockpit fold away in a small room?
Some can. The foldable listing at £694.19 folds from 136 cm to a 27 cm profile, though the steel foldable listed at £173.99 gives its size as 70.9 x 33.1 x 37.4 in, so measure the space you have for the unfolded rig as well.
