Simucube 3 Guide: Why are they considered the best on the market is Simucube?

Simucube 3 Sport, Pro or Ultimate? The key differences

Simucube bases feature industrial motors with high-quality Finnish controllers, making them the top bases on the market for many years. A broken Simucube is a legend rarely heard of or seen. If we had to choose one brand, we'd recommend Simucube. The manufacturer has perfected the driving experience over the years, and the hardware is designed to provide thousands of hours of trouble-free use.

The Simucube 3 range includes three Direct Drive wheelbases: Simucube 3 Sport, Simucube 3 Pro and Simucube 3 Ultimate. They deliver 15, 25 and 35 Nm of peak torque respectively.

That does not mean the most powerful model is automatically the best one for you. Your choice should also take into account the weight and diameter of your steering wheel, the stiffness of your cockpit, how strong you want the force feedback to feel and how much headroom you need before clipping occurs.

Sport and Pro are the sensible choices for most home rigs. Pro works better with heavier wheels and provides more torque headroom, while Ultimate is aimed at the most demanding setups and professional applications.

What matters besides peak torque?

The torque figure tells you how much force a wheelbase can produce, but it does not tell the whole force-feedback story. The speed at which the torque changes, motor smoothness, control and the ability to preserve short details through a heavily loaded corner all matter as well.

Torque Slew Rate

Torque Slew Rate describes how quickly the torque can change. A high value helps the wheelbase reproduce kerbs, sudden slides and quick countersteering inputs with clarity. All three Simucube 3 models are rated at 9.5 Nm/ms, so Sport can react just as quickly as Pro and Ultimate. The more powerful models, however, retain more headroom when the wheelbase is already producing high torque for a longer period.

Motor and encoder

Sport and Pro use SPM servomotors, while Ultimate features a spoke-type IPM motor. Every model is equipped with a 23-bit absolute encoder. In practice, signal quality depends on how well the motor, sensor and control electronics work together—not simply on the encoder's position count.

Steering wheel and cockpit

A large, heavy wheel has more inertia and reduces the force you feel in your hands. This is why 15 Nm can feel very strong with a lightweight Formula wheel but more relaxed with a substantial GT or rally wheel. A rigid mounting point is just as important: if the cockpit flexes, some of the finer detail disappears into the frame instead of reaching your hands.

Simucube 3 Sport, Pro and Ultimate compared

Simucube 3 Sport - the best choice for most drivers

Simucube 3 Sport delivers 15 Nm and the full 9.5 Nm/ms Torque Slew Rate. That is enough for strong, fast and detailed force feedback, with useful headroom for kerbs, slides and short impacts.

Sport works best with lightweight and medium-weight Formula or GT wheels. It will also handle a large rally rim, although the lower torque reserve becomes easier to notice.

  • For drivers upgrading from a wheelbase in the 5–12 Nm range
  • For a premium home cockpit
  • For drivers who do not want an extremely heavy FFB profile
  • For lightweight and medium-weight steering wheels

Simucube 3 Pro - more headroom for heavier wheels

Simucube 3 Pro produces 25 Nm. The extra 10 Nm over Sport does not mean the wheel has to feel heavier all the time. Its biggest advantage is the additional headroom, which helps preserve the difference between individual signals when the wheelbase is working hard.

Pro is better suited to large GT wheels, heavy hubs and steering wheels with built-in displays. It is also a sensible option for drivers who spend long hours in the simulator, prefer stronger settings or want to build a final rig without replacing the wheelbase later.

  • For heavier steering wheels and large rims
  • For strong force-feedback profiles
  • For league racing and intensive training
  • For drivers who want plenty of headroom before clipping

Simucube 3 Ultimate - 35 Nm and an IPM motor

Simucube 3 Ultimate is the most powerful model in the range. It offers 35 Nm, a spoke-type IPM motor and the greatest headroom with heavy steering wheels and sustained high loads.

Most home users will never need a constant 35 Nm—and their shoulders may be quite happy about that. Ultimate makes the most sense in professional simulators, training centres, rigs used for many hours every day or no-compromise setups fitted with a very heavy wheel.

  • For professional and commercial use
  • For very heavy steering wheels
  • For rigid cockpits designed to handle 35 Nm
  • For users specifically looking for an IPM motor

Simucube 2 or Simucube 3?

Simucube 3 is the newer platform, but that does not suddenly make the previous generation weak. Simucube 2 Sport produces 17 Nm, while Simucube 2 Pro delivers 25 Nm and remains a very capable wheelbase.

The new generation adds front and bottom mounting, the Simucube Link platform, Link Quick Release and a Control Box for convenient adjustments. Simucube 3 Sport has less peak torque than its predecessor, but a considerably higher stated Torque Slew Rate.

If your Simucube 2 is set up well and does everything you need, there is no reason to rush the upgrade. Moving to Simucube 3 makes more sense when you are building a completely new rig or want to enter the Link ecosystem. A Link Quick Release adapter for Simucube 2 is also available. It lets you use the new mechanical connection, although it does not add full Link connectivity to the wheelbase.

Looking for a steering wheel for Simucube 3? Simline wheels can connect wirelessly

When you select the wireless version on the product page, a Simline steering wheel does not require a USB cable running to the PC. It communicates through the Simucube Link Hub, keeping the rotating assembly free from a trailing data cable.

FAQ — Questions and answers

Is 15 Nm enough in Simucube 3 Sport?

For most users, yes. Sport delivers strong and responsive force feedback. Pro is mainly worth considering if you use a heavy steering wheel or want more torque headroom.

Is Simucube 3 Pro worth the extra cost

Yes, if you use a heavy wheel, prefer a strong FFB profile or want to reduce clipping under high load. If the price gap is modest when you buy, Pro is well worth considering.

Does Ultimate make sense in a home setup?

It can, but Pro already provides more than enough headroom for most drivers. Ultimate is easiest to justify with very heavy wheels, rigs used for many hours a day or professional applications.

What does 9.5 Nm/ms mean?

It is the stated maximum rate at which the torque can change. This affects the clarity of short events such as hitting a kerb, making a quick correction or catching a sudden slide.

Is a higher Torque Slew Rate always better?

It is good to have the available performance, but the maximum setting is not always the best one. An overly aggressive profile can feel nervous and tiring, especially with a lightweight wheel. The setting should suit both the car and the steering wheel.

Is the Simucube Link Hub required?

Yes. Simucube 3 uses the Link Hub to connect to the PC. One hub can support several compatible devices, allowing a compatible Simline steering wheel and Simucube pedals to share the same Link connection.

Can I use a USB steering wheel from another brand?

Yes. An independent USB steering wheel can still be connected directly to the PC. You only need to make sure that you have the correct mechanical mounting solution.

Can Simucube 3 be mounted from the bottom?

Yes. Unlike Simucube 2 wheelbases, the Simucube 3 range supports bottom mounting as well as front mounting.

Is it worth replacing Simucube 2 Pro with Simucube 3 Pro?

The Series 3 features a new controller and a new engine, making FFB more responsive and crisp. Simucube 3 offers many more customization options to suit user preferences. Having had the opportunity to drive the Series 2 and Series 3, the differences aren't dramatic, but they are clearly a plus for Simucube 3.

Where to buy Simucube 3?

It is best to purchase the base from an authorized seller of the brand, such as simline.eu, thanks to which the customer can be sure that the store will provide appropriate after-sales support.

Which model should you choose?

For most drivers, Sport is the best place to start. Choose Pro for heavier wheels, stronger force feedback and more headroom. Ultimate is for drivers and professional users who will genuinely take advantage of 35 Nm, the IPM motor and the greatest available torque reserve.
