The steering wheel is the part of your simulator you interact with most. Its shape affects how quickly you can work with your hands, its diameter changes how the force feedback feels, and its controls determine how much you can adjust without releasing your grip. There is no single wheel that is best for everyone—but there is a type that will suit your driving better.
Short answer: choose a Formula wheel for formula cars and prototypes, a GT wheel for modern GT and circuit racing, and a round wheel for rally, drifting, historic cars and maximum versatility.
Formula, GT or round—what is the difference?
| Wheel type | Typical diameter | Best suited to | Main strength | Keep in mind |
|---|---|---|---|---|
| Formula | approx. 270–290 mm | Formula, prototypes, fast GT cars | Fast inputs and many controls close to your hands | Less natural when the wheel needs to rotate a long way |
| GT | approx. 295–320 mm | GT3, GT4, touring cars and circuit racing | A strong balance of precision, comfort and control | Not as easy to catch as a fully round rim |
| Round | approx. 320–350 mm | Rally, drifting, historic cars, trucks and mixed driving | Natural with large steering angles and hand-over-hand inputs | A larger diameter can reduce perceived force |
Formula wheel—built for precision and fast commands
A Formula wheel is compact and open at the top and bottom. Its smaller diameter makes direction changes quick and often delivers an intense, direct feeling from the wheelbase. The shape works particularly well in cars with limited steering rotation, where your hands stay at roughly nine and three o’clock.
Formula wheels often include numerous buttons, encoders, thumb wheels, dual-clutch paddles and an integrated display. These controls are valuable in cars where you adjust brake bias, traction control, ABS, energy deployment and engine modes while driving.
Choose Formula if: you mainly drive formula cars, LMP/hypercars or modern race cars and want maximum control without moving your hands.
Choose another format if: you frequently drive rally, drift or cars that require large steering angles. The open shape is less forgiving when the wheel needs to slide through your hands.
Example: SIMAGIC Zeus Formula is a clear Formula option in a 280 mm format.
GT wheel—the versatile circuit-racing choice
A GT wheel sits between a Formula wheel and a round wheel. It is normally wider than a Formula wheel, has substantial grips and may be open or flat at the top and bottom. The larger diameter produces calmer movement and greater leverage while still keeping your hands in a clearly defined working position.
For many drivers, a GT wheel is the best first choice. It is ideal for GT3, GT4, touring cars, one-make cups and many other forms of circuit racing. A well-equipped GT wheel can offer nearly as many controls as a Formula wheel while providing more space for your hands and strong comfort during longer sessions.
Choose GT if: you primarily drive on circuits and want a focused wheel that is not overly specialised.
Example: MOZA KS Pro is a versatile 300 mm GT/Formula wheel for modern circuit racing.
Round wheel—for rally, drifting and maximum freedom
A round wheel can be gripped anywhere around the rim. That matters when it rotates through a large angle, when you steer hand over hand or when you need to catch it quickly after a slide. This makes it the natural choice for rally and drifting, as well as historic cars, road cars, truck simulators and other driving where a traditional steering wheel feels right.
A diameter of around 320–330 mm gives a car-like feel and works across many disciplines. A larger wheel may add realism in certain cars, but it needs more space and reduces the force you feel in your hands from the same wheelbase.
Choose round if: you want to drive many different vehicle types or regularly use large steering angles.
Example: SIMAGIC Neo X Series can be configured with 330R/330T for rally and mixed driving or 350W for drifting.
Diameter changes the force-feedback feel
Two wheels on the same wheelbase can feel surprisingly different. A smaller wheel provides less leverage, making the force feel more concentrated and direct. A larger wheel gives you more leverage, calmer movement and may feel weaker even when the wheelbase setting has not changed.
This does not mean that larger or smaller is always better. Match the diameter to the car, your driving style and the strength of your wheelbase. A compact Formula wheel can feel extremely lively on a powerful direct-drive base, while a larger round wheel often creates a more natural movement for rally and drifting.
Weight and rotational inertia affect detail
The weight of the steering wheel also affects how the force feedback feels, but total weight does not tell the whole story. How the mass is distributed is just as important. Mass positioned near the outer rim creates more rotational inertia than the same amount of mass placed close to the centre.
A wheel with greater rotational inertia requires more torque to accelerate and decelerate. Rapid changes in the force-feedback signal can therefore feel softer, and some fine details may become less distinct. A lighter wheel, or one with more of its mass concentrated near the hub, can respond faster and feel sharper in your hands.
This does not mean that the lightest wheel is always the best choice. Some inertia can create calmer movement, reduce nervousness and provide a more car-like feel. The effect is most noticeable on less powerful wheelbases, but it is also present on strong direct-drive systems. When comparing wheels, consider not only their total weight but also their diameter, construction and mass distribution.
Four things to check before buying
1. Wheelbase compatibility
Always check how the wheel connects. Some wheels communicate directly with a wheelbase in the same ecosystem. Others use USB to the PC and require a compatible quick release or adapter for the mechanical connection. A wheel can therefore fit mechanically without every button, paddle or display function working automatically.
2. Grip material and ergonomics
Suede and Alcantara provide a secure grip but benefit from gloves and regular care. Leather and synthetic leather are easier to clean and work well without gloves. Also consider grip thickness, paddle reach and whether you can reach the controls without changing your hand position.
3. Paddles and controls
Two good magnetic paddles are enough for sequential shifting. Dual-clutch paddles are particularly useful for standing starts. Additional encoders and thumb wheels are valuable in advanced racing cars—but only if you can identify and reach them while driving.
4. Display and software
An integrated display can show gear, RPM, delta, tyre data and warnings. Check which games and telemetry solutions are supported. SimHub support often provides extensive flexibility, while a manufacturer’s own software may deliver a simpler setup inside the same ecosystem.
Choose according to what you drive
- Formula and prototypes: start with a Formula wheel around 270–290 mm.
- GT3, GT4 and touring cars: choose a GT wheel around 295–320 mm.
- Rally and drifting: choose a round wheel around 320–350 mm.
- Mixed driving with one wheel: a round wheel or versatile GT wheel is usually the easiest option.
- Multiple disciplines: choose a quick-release system that makes switching between two wheels straightforward.
Our recommendation
Start with the type of car you drive most—not the wheel with the longest feature list. The right shape and diameter affect every corner, while extra controls only help when you actually use them. For dedicated Formula driving, a compact Formula wheel is hard to beat. For modern circuit racing, the GT format offers the strongest balance. For rally, drifting and maximum variety, a round wheel is the safest choice.

Frequently asked questions
Can I use a Formula wheel for GT cars?
Yes. Many modern GT cars use limited steering rotation and work very well with Formula-style wheels. A wider GT wheel can, however, provide greater comfort and a more car-specific grip.
Is a larger wheel better for a strong direct-drive base?
Not automatically. A larger wheel provides more leverage and can make the force feel smoother. Choose diameter according to car type and ergonomics, then adjust the force feedback.
Do I need a display on the wheel?
No. A display is useful when the screen or simulator instruments are difficult to see, but it is not required for good driving feel. Grip, paddles and compatibility matter more.
Which type is best for a first wheel?
For mixed driving, a round wheel or versatile GT wheel is usually the easiest choice. If you almost exclusively drive Formula cars or prototypes, you can choose a Formula wheel from the start.
