MOZA Racing mBooster Active Pedals – Review

MOZA Racing mBooster Active Pedals – Review

Hardly any other area of simracing has developed as much in the recent past as pedals. In addition to the increasingly widespread Hatpic motors, active pedals in particular are now regarded as the non-plus ultra. This is where the new mBooster pedals from MOZA Racing come into play, with a price tag of €899, they bring the price down a considerable amount. This test will show how the latest highlight in the MOZA line-up performs.

Ordering and shipping

As usual with MOZA, the pedals can be ordered both from MOZA’s own shop and from various third-party suppliers. MOZA offers the pedal individually as well as a bundle consisting of the mBooster Active pedal and the standard components of the CRP2 set (review).

Compatibility

The mBooster Active pedal is currently only intended for use with a computer. For this purpose, the pedal is connected directly with the USB cable (USB-A) supplied. This means that the pedal can also be combined with any standalone pedals. There are several different combination options within the MOZA ecosystem:

• mBooster Active Pedal + CRP2 Pedals: In combination with the pedals of the CRP2 set, the mBooster pedal replaces the controller box and the throttle (and optionally also the clutch) are connected directly to it.
• mBooster Active Pedal + CRP Pedals: Just like the newer CRP2 set, the pedals of the CRP pedal set are also compatible with the mBooster pedal and can be connected directly to it. MOZA recommends the CRP2 base plate, which has mounting holes compatible with the CRP pedals.
• mBooster Active Pedal + mBooster Active Pedal: When using two or three mBooster Pedals, they are connected to each other (see diagram in the instructions!). However, each pedal requires its own power supply unit.

When using a MOZA Wheel Base, it is also possible to connect the pedals directly to the Wheel Base using the cable supplied.

The pedals are basically input devices with normal analogue axes and can therefore be used with any current racing simulation without any problems. The situation is slightly different with the telemetry effects. MOZA has to ensure compatibility here. Here is the current list at the time of the review, which will be significantly expanded in the future:

Mounting

MOZA has given some thought to mounting and has already designed the CRP2 set, which has been available for a few months, to accommodate the mBooster Active Pedals. The appropriate mounting holes are therefore already integrated and the new Active Pedals can be mounted in the desired position in just a few simple steps. A clear recommendation here is the optional Extended Plate, which extends the base plate of the CRP2 pedals to the rear and provides more stability.

Of course, aluminium profiles can also be used to mount the Active Pedal; four M8 T-nuts in combination with the supplied screws are sufficient for secure mounting.

Overall, with a total length of 382.5 millimetres and a height of 234 millimetres, the mBooster Active pedal is still comparatively compact, but of course significantly longer than most conventional pedals. In combination with the CRP2 base plate, a total length of approx. 55 centimetres must be expected.

mBooster Active Pedal

For the mBooster Active pedal, MOZA has opted for a construction made of black anodised aluminium with gold accents and has based its design language on the CRP2 pedal set.

Technology

While most current simracing pedal sets have dedicated pedals for the throttle, brake and clutch, an active pedal can be used universally. This is because instead of using rubber elastomers or metal springs to generate the resistance and thus the pedal feel, you press directly into the controllable motor, which is located at the rear end of the pedal, via a ball screw. MOZA integrates the appropriate hardware to measure the pedal travel and pedal force:

• 2 x 200 kg Load cells sensors:They are located directly behind the pedal plate and measure the force exerted by the operator on the pedal.
• 15-bit angle sensors: Angle sensors are installed in the lower section of the pedal, which operate with a resolution of 15 bits and can determine the deflection of the pedal.

In combination with the built-in motor, the pedal feel can be fully customised to your own needs via a force- travel curve, making it much more individual than would be possible with conventional elastomer combinations.

Probably the biggest advantage over conventional pedals is the ability to adjust settings such as the maximum travel or the required braking force in fractions of a second with just a few mouse clicks, without having to change the pedal mechanically.

Thanks to the closed system, the pedal is surprisingly quiet in operation with peaks of approx. 40 – 50 decibels, especially as a brake, and thus remains within a volume range measured from a distance of one metre that does not have a negative impact during normal driving (especially when using a headset). However, the pedals (as of March 2025) are quite loud in standby mode. The volume depends on the respective setting of the pedal and is clearly perceptible, so that in case of doubt it is better to disconnect the pedal from the power supply when not actively driving.

Ports

The pedal connections are located on the right and left sides:

• Left: On the left-hand side is the connection for the power supply as well as a port for the clutch and a port for the optional direct connection of the pedal to a MOZA base.
• Right: The connection for the throttle pedal is located on the right-hand side. The USB port for connecting the pedal to the PC is also located here.

The connections are arranged so that the cables can be routed either directly to the side, to the rear or downwards through the slot in the base plate.

Pedal Plate

The pedal plate is a familiar sight. Thanks to its textured surface, the milled aluminium plate offers a successful compromise between grip and a surface that is not too rough. This makes the pedals very comfortable to use both with and without shoes.

The inclination can be adjusted in a range of approx. 15° using slotted holes and the tool supplied. In addition, the position can be further adjusted by dynamically setting the start and end points of the pedal travel via the software.

Use as a brake pedal

The mBooster Active pedal’s speciality is undoubtedly its use as a brake. This is where it can realise its full potential and offers a wide range of adjustment options:

• Pedal Force Feedback Curve: The behaviour of the pedal can be set here in a freely configurable curve (pedal travel depending on the force).
• Force: Two sliders can be used to configure both the force required for the maximum pedal travel in a range from 30 to 200 kilograms and a dead zone (up to 30 kilograms).
• Pedal Travel: The software can be used to set the maximum pedal travel in a range from 4.3 to a maximum of 32.1 millimetres. The start and end point can be freely adjusted within a range of 3.8 to 49.7 millimetres.
• Natural damping: The damping of the pedal can be set separately in two phases. The first phase relates to pedal actuation and therefore to damping during braking. Very low values have proven themselves here during testing. The second phase relates to release. The higher the setting, the longer the pedal takes to return to the starting position. This can be helpful when trailbraking, for example, but of course also makes the pedal less direct.
• Natural Friction: This setting simulates additional friction. During testing, this setting was almost always deactivated.
• End Stop Feeling: The hardness of the respective end stops can also be set, again separately, in a hardness range between 1 (soft) and 10 (hard).

But what really counts is the practical experience. And this is where the mBooster Active Pedal does an excellent job as a brake pedal. In just a few minutes and with a little effort, you can imitate a ‘normal’ Loadcell brake, for example, which you have become accustomed to over hundreds of hours of driving. The pedal feels very natural and the very smooth operation means that you never feel like you are working against a motor.

What definitely sets the pedal apart from normal systems, however, is its adjustability. With just a few clicks, you can make adjustments that you would otherwise have to use a tool for. Changing a setting, driving a few metres and then refining it further is so incredibly easy and intuitive. It also makes switching between different vehicle classes with very different characteristics even more fun. Whereas with a normal brake pedal you generally choose a certain universal middle ground and usually only adjust the required braking force, you can now theoretically create and use a completely individualised profile for each vehicle.

There is also the option of adding various brake-specific telemetry effects:

• ABS: Probably the most important effect is the ABS function, which can be adjusted in terms of intensity, frequency and smoothness. This causes the pedal to pulsate noticeably when ABS is active and can be very helpful in iRacing, for example, to avoid using too much brake pressure.
• Brake Threshold Vibration: Another aid can be the vibration function, which provides clear haptic feedback from a pre-set point (adjustable between 50 and 100% brake pressure). This can help to find the right brake pressure for different vehicles, especially during training. The effect can be used independently of the simulation and does not require any sim-specific telemetry data.
• Wheel lockup: This can be used to emit a vibration when the wheels lock, if this is supported by the simulation.

The effects for TC and Engine Vibration can also be assigned to the brake pedal, but if in doubt, they are better placed on the other pedals.

For the test, the pedal was operated with a sensor output ratio of 100% on the side of the angle sensor. This means that the set maximum force must be applied over 100 % of the travel. The behaviour up to this point can be set in freely configurable curves so that, for example, very progressive or even degressive settings can be simulated.

Use as a throttle pedal

In addition to being used as a brake pedal, the mBooster Active Pedal can also be used as a throttle pedal. The following settings can be made:

• Pedal Force Feedback Curve: As when used as a brake pedal, the behaviour of the pedal can be set here in a freely configurable curve (pedal travel depending on the force).
• Force: Setting the maximum (4 to 20 kilograms) and the initial force required (0 to 4 kilograms). This corresponds to a force range that covers almost all currently available pedals with metal springs.
• Pedal Travel: The pedal travel can also be configured when used as a throttle pedal. This time in a range between 10.7 and 45.9 millimetres.
• Natural damping: Additional damping in both directions can also be configured here. In particular, the effect when releasing the pedal is even more noticeable here due to the reduced force when accelerating. With (unrealistic) extreme settings of 100% damping in conjunction with a minimum force of 4 kilograms, for example, the pedal takes over 2 seconds to return to the starting position, whereas with 0% damping and 20 kilograms of force it only takes a fraction of a second.
• Natural Friction: Additional friction is simulated here. This setting was always deactivated during the short test run as a throttle pedal.
• End Stop Feeling: The hardness of the respective end stop can be set, again separately, in a hardness range between 1 (soft) and 10 (hard).

The mBooter Active pedal also cuts a fine figure as a throttle pedal, but does not shine as much as a brake pedal. Even though it can be just as handy here to make the settings on the fly, the advantages over the regular CRP2 throttle pedal with its two different usable springs are less than when used as a brake pedal.

The following effects are possible for the throttle pedal:

• TC: As soon as the vehicle’s traction control is active, the driver receives haptic feedback on the accelerator pedal, the intensity and frequency of which can be adjusted. This can help to control the pedal more sensitively at the exit of a bend without getting fully into TC.
• Engine vibration: The vibration of the engine can also be displayed as an effect. This is primarily used for immersion, but has no direct influence on the driving behaviour.

Use as a clutch

Of course, the Active Pedal can also be used as a clutch. In addition to the travel-force curve, a bite point can be defined in the range from 5 to 95 percent, which is then indicated with haptic feedback. This effect can be set without telemetry data from the simulation. You should therefore first find out the correct bite point for each vehicle yourself, as very few simulations provide information or even telemetry data on this. There are the usual suspects for the other parameters:

• Pedal Force Feedback Curve
• Force: Setting the maximum (4 to 20 kilograms) and the initial force required (0 to 10 kilograms).
• Pedal Travel: Adjustable pedal travel in a range between 10.7 and 45.9 millimetres.
• Natural Damping
• Natural Friction
• End Stop Feeling

Comparison with conventional pedals

As already mentioned several times, the mBooster Active pedals are characterised above all by their adjustment options and the associated versatility. While with conventional pedals you can spend an hour or two in awkward poses half under your Simrig to adjust them, here you can make almost any desired setting with just one click of the mouse. Be it a different pedal travel, the force applied or the behaviour of the pedals themselves.

Added to this are the telemetry effects, which, thanks to the motor, are significantly more powerful and lively than normal shakers, which are now integrated into many pedal sets.

For the classic GT3-only driver, the advantages are therefore significantly less than for drivers who frequently change vehicles and drive in different classes.

Software

MOZA has dedicated a separate area in the software (MOZA Pit House) to the mBooster Active Pedals. Here you can set the individual effects described, configure the behaviour and perform a motor and pedal travel calibration.

It is also possible to choose between various preset profiles for different classes such as Formula, GT, Hyper Cars and Street Cars.

Driving impression

Conclusion

The mBooster Active Pedals are probably the most interesting new release on the simracing market in 2025 to date. With a price of under €1000, active pedals are becoming affordable for a much wider range of simracers, even if they still remain an absolute high-end product.

In combination with the separately available Extended Plate, the pedals can either be seamlessly integrated into an existing CRP2 pedal set or used individually as stand-alone pedals.

In addition to the various possible effects such as ABS and TC, the main advantage over conventional pedals is clearly the incredible customisability, which allows an mBooster Active pedal to fundamentally change its entire characteristics with just a few mouse clicks. Especially those who are frequently on the track with different vehicle classes will get their money’s worth with the mBooster Active Pedals.
