MOZA Racing mBooster Pedal Review

Going back a few years to the end of 2021, sim racing saw a big change with the introduction of affordable direct drive wheel bases. Fanatec had just launched the CSL DD, and this was followed a few months later by MOZA Racing with the R9, the R5 wheel bases.

This change at the end of 2021 signified the end of direct drive wheels being seen as premium-only technology. The same is now happening in 2025, this time with sim racing pedals.

Simucube has released two versions of its ActivePedal over the past few years, which was originally the world’s first true force feedback pedal. Much like direct drive wheels back in the day, these ActivePedals are extremely premium.

MOZA Racing has now broken down some of the barriers to entry for ActivePedals with the mBooster pedal. This is a pedal that packs a lot of the same punch as a £/$2,000+ Simucube ActivePedal, for well over half the price.

Thanks to MOZA sending us an mBooster pedal to test, in this review, I’m going to be putting this pedal through its paces to see if it is as innovative and game-changing as those small, affordable direct drive wheels from a few years ago.

Below is our in-depth MOZA mBooster Active Pedal Review.

What is the MOZA Racing mBooster Pedal?

So lets start at the top, with the question, “what is an active pedal?” Up until recently, sim racers have become used to the three forms of pedals available.

• Potentiometer pedals: You have potentiometer pedals, your typical angle sensor, budget pedal option, think Logitech G923.
• Load cell pedals: Moving up in realism and cost are load cell pedals. These measure the force applied to the pedal, and allow for much better consistency.
• Hydraulic pedals: Then at the top of the tree were hydraulic pedals, which use a hydraulic cylinder, which replicates the system used in a real-world car.

Active pedals sit above hydraulic pedals in terms of cost, and differ from all of the mechanical pedals just listed. The mBooster pedal, and other active pedals use an internal ball screw motor to control all aspects of the pedal travel and resistance.

Detecting the input are dual load cell sensors which can detect up to 200kg of input force each. There is also a 15-bit angle sensor which can work alongside the load cell sensors to enhance the input precision.

It’s this motor that is responsible for the brake pressure and pedal travel, but it also brings some additional tricks to the party. The motor can produce force feedback, just like a racing wheel. This opens up a huge amount of FFB effects that can be sent through the pedal for extra feedback while on track.

You can set the pedal to rumble when your ABS or traction control activates. You can opt for feedback to tell you when your wheels are locking, or when you’ve reached a specific amount of brake input.

Another benefit of an active pedal is that the motor is software-controlled, allowing for quick adjustments without needing to physically adjust the pedal. The beauty of this approach is that you can quickly change your pedal for different scenarios. One preset could be for a short-travel and really stiff F1 experience, and then, with a click of a button, you can load in your GT preset, which has less brake pressure and a much longer travel.

Price of the MOZA mBooster Pedal

So how much does this mBooster pedal cost? Well, you can buy the mBooster pedal in a few configurations. Buying a single pedal will cost you $799, £799 or €899.

That will net you just one mBooster pedal which will need to be paired with a throttle, although the beauty of an mBooster pedal is that you can use it with any other pedal from any brand, as it connects directly to your PC.

You can choose to buy a two pedal combination of the mBooster and a CRP2 throttle, plus the baseplate. This will cost $999, £999 or €1,099.

How does this price compare to the Simucube ActivePedal?

At the time of release, there are only two other active pedals available, and both are from Simucube. So naturally, this is a great time to compare them to the mBooster pedal.

Simucube’s entry-level active pedal, the Pro, is available to buy separately for £1,470, $1,720, or €1,700. Depending on your region, that’s close to double the cost of the mBooster. Simucube also has the ActivePedal Ultimate, which boasts a few additional features to the Pro. It costs £2,115, $2,300, or €2,420, almost triple the cost of a single mBooster pedal.

The feature set does differ slightly from the mBooster, and there are reasons why you may want to opt for an ActivePedal over the mBooster, which I’ll touch on more later.

Unboxing and what’s included

Lets go back to the mBooster pedal, and see whats included in the box. To start, you’re greeted with the standard instructions, followed by a large PSU brick and a range of connection cables. You can connect this pedal to a PC directly, or to a MOZA wheel base, and cables are included for both options.

You then get the pedal itself, wrapped in MOZA’s signature fabric protection bag.

The design & build quality

You can tell the quality of this mbooster pedal simply due to its weight, and that is thanks to the all-metal construction and internal motor. The exterior of the pedal is finished in a satin black, allowing it to blend right into any sim racing setup, and look right at home next to the CRP2 pedals.

The design of the pedal plate and the vertical pedal arm match the CRP2 almost identically, and this creates a really cohesive looking pedal set when paired together. This is almost certainly one area of cost saving that leads to the lower mBooster price.

The design of the motor housing is remarkably different to Simucube’s approach. The entire motor is housed in the moving pedal arm, rather than a static base. This motor housing is hinged at the center point and results in the whole pedal rotating and moving as you race.

It’s different and a bit more fluid than Simucube’s approach, and I kind of like it. The pedal plate has the usual range of adjustments, including the angle and height of the plate. However, outside of this, the pedal itself has no physical adjustments. Everything else is controlled via the internal motor.

Dimensions

With the Simucube ActivePedals, one key area was the increased dimensions due to the internal motor. The ActivePedals which are 418mm in length, do require a lot of room to mount.

The MOZA mBooster pedal is more compact, but not by a huge amount. They measure in at 382mm in length. If you’re using an mBooster pedal with a CRP2 pedal set, you will require an extension plate in order to mount the pedal safely.

Mounting the pedal

At both the front and rear of the pedal, you’ll find two mounting holes, resulting in four total. These mounting points allow you to mount the pedal either directly to your sim rig’s pedal plate, or they fit perfectly on the MOZA CRP2 baseplate.

If you’re mounting to the baseplate, the pre-drilled holes are threaded, making it slightly easier to mount to compared to a sim rig that may require either a nut or a t-nut depending on your setup.

One area to note, though, is just how tricky it can be to mount through the rear two holes. The two pre-drilled holes sit right under the rear of the pedal, and you need an incredibly shallow Allen key to access this area.

I would have preferred that MOZA flaired this section out to make rear mounting much easier. There is plenty of space to do so, as the side-entry data and power cables block any pedal being mounted too close.

Compatibility of the mBooster Pedal

Talking of these cables, there are a range of connection points on the mBooster. On the left side, you have the USB data cable connection which is used to send data directly to your PC. Next to this is a slot for a throttle cable.

On the other side, you’ll find your slot for the power cable, clutch pedal, and another port labelled base. This can be used instead of the USB port, to connect the pedals directly to your MOZA wheel base. You may want to do this to avoid another USB cable entering your PC.

The mBooster is a PC-only sim racing pedal, and unlike the CRP2 pedal, it cannot be used with consoles. This is no surprise at this price point and is common among premium sim racing hardware.

Adjustability & FFB effects

Outside of the excellent build quality which can be found on many premium sim racing pedals, the software adjustments and force feedback effects is the real reason why you’d consider an active pedal.

MOZA uses its Pit House software to configure and adjust everything to do with the mBooster pedal. this software is immediately familiar if you’ve used any MOZA hardware in the past, and the mBooster slots right in.

Within the pedal screen, you have options to configure the mechanical pedals, just as you would if you were using the CRP2 pedals on their own. But its in the brake settings that all of the magic can be found.

Pedal feel

The first page lets you adjust the mechanical feel of the brake. You can change the preload strength, along with the force feedback curve, the brake pressure, and the pedal travel, and it all looks eerily similar to Simucube’s own software.

Scrolling down, you get options to change both the damping and friction of the pedal travel, both of which I’ve set pretty low to avoid the pedal feeling sluggish. You can then change the bump stop feeling from soft to hard using a sliding scale, although the difference between 1 and 10 was barely noticable.

Input mapping

You can adjust your input curve and change the balance between the load cell and angle sensor. Adjusting this can dramatically affect how the pedal input is processed, and there is a fine balance to be found here.

Effects settings

Finally, we have the effects settings. Here, we can enable or disable various settings and fine-tune each one. There are a good amount of effects to tinker with, although admittedly not as many as the Simucube pedal at launch. The notable exception is the lack of G-force effects, which is one of the more immersive effects on the Simucube pedal. I have been told, though, that this effect is coming with an anticipated launch date of late March or early April.

The effects you do find though are fairly comprehensive and let you configure the mBooster as a throttle, or brake nicely.

The full list of effects for the pedal version I tested included;

• Engine vibration: This is a high frequency rumble that increased in line with the engine RPM.
• ABS: The ABS effect vibrates to varying strengths as your ABS activates in game. This is ideal for road cars or GT cars which utilise ABS and are often pushed to their limit while racing.
• Traction control: You can enable a similar rumble to the ABS that triggers as the traction control is activated in game.
• Brake threshold vibration: You can set a specific threshold for how much input you apply, and when you reach this threshold, you’ll feel a vibration in the pedal. This is ideal to prevent you from braking too hard or locking a wheel.
• Wheel lockup: Much like the ABS or TC effects, you can enable the wheel lockup effect, which lets you feel when you lock a wheel.

The beauty of these effects are that you can mix and match as needed. If you’re only running a single mBooster pedal, you can enable all effects to feel the brakes, wheels, engine and traction control all through a single pedal.

To me, trying this muddied the vibrations as the pedal would be constantly rumbling or vibrating. I preferred, disabling some of the effects such as the traction control and brake threshold, leaving me with clear vibrations when I overstepped the mark under braking.

If you are using multiple effects, such as ABS, wheel lockup and brake threshold, which will all combine during the braking phase, you can set distinct frequencies for each effect. This will let you easily differentiate between an ABS vibration and a wheel lockup vibration, as they can feel remarkably different.

Telemetry vs independent effects

Most of the effects on the mBooster are telemetry-based, meaning they activate based on the live telemetry from inside your racing sim. This does mean that the available effects will differ between games.

Assetto Corsa Competizione for example has all effects available to use, while iRacing doesn’t currently support the wheel lockup effect, and sims such as Le Mans Ultimate, don’t support any effect outside of motor vibrations.

One effect that is independent of game is the brake threshoold effect. This is activated by simply setting an input threshold in MOZA’s software. Then, as you reach that amount of input, the effect will trigger.

This isn’t something I regularly use while racing, primarily GT and F1 cars. However, it can be beneficial if you’re racing a car without traction control, like an open-wheeled car or GT Cup car where you can’t apply 100% brake input.

Setting the brake threshold effect to trigger at say 70% input will let you build up muscle memory over time. This can help you improve your precision and consistency with various cars.

Presets

If all of the adjustments seem overwhelming at first, you can load a range of presets that will quickly configure the pedal for you. There are presets pre-built into Pit House for different racing disciplines, as well as presets by various content creators.

The presets don’t currently have the same level of pro racing driver quality as Simucube. With an ActivePedal Pro or Ultimate, you can select presets from legends such as Tony Kanaan and drivers such as Gabriel Bortoleto and Daniel Morad.

Having tried many of the MOZA presets, I can say that they are good for baseline configurations and give you a good starting point. However, most presets have all effects enabled by default, so I’d recommend turning some effects that you don’t need off.

Performance review

So, when you jump onto the track, how does the mBooster pedal perform? Well, the answer is pretty damn good. I would highly recommend setting up the pedal in Pit House, testing all of the effects and trying some presets before hitting the track.

During my first session, with the brake pressure set pretty high, I could barely activate the brakes. After some quick tweaks in Pit House, I was away, and everything instantly started clicking into place.

This is one huge perk of an ActivePedal. To change the resistance, I didn’t need to jump out of my racing seat, grab an Allen key, or make any physical adjustments. It was just a quick two-second change in the software.

The software changes allowed me to tinker with various settings and presets and really try the pedal out in various scenarios. For example, when racing a GT3 car, you want to apply a large amount of brake pressure initially before modulating the input in line with the ABS system activating.

With the mBooster pedal using a GT configuration, I could brake hard on the entry and keep more input applied before I started to modulate it. This confidence came in the fact that I could feel the ABS activating under my foot if I overstepped the mark, and over time, my muscle memory improved.

This effect gives me an instant advantage over using a traditional mechanical pedal, as I can feel the car much more on the approach to every turn. The initial pedal input was also every bit as smooth as a traditional pedal would be.

I’ve primarily used the mBooster with F1 and GT3 cars, so I’ve created presets for both of these racing disciplines. This lets me quickly switch between the two. I can have a long pedal travel and effects such as ABS enabled for GT racing, and shorten the pedal travel, increase the force and disable the ABS effect for formula cars.

With the damping and friction effects lowered, this active pedal is extremely responsive, and you feel an overwhelming sense of control throughout each braking motion. The feel of a traditional brake pedal is controlled via elastomers or a hydraulic cylinder, and they can be incredibly tricky to dial in to feel just right. With overwhelming control over every brake input stage, you can set up the mBooster pedal to feel exactly how you want, even replicating real-world cars very closely.

Immersion vs performance

The effects of the mBooster are broken into two categories, immersion and performance. Effects such as the engine RPM won’t add anything to your performance, however, they do add immersion by letting you feel the car through your pedals.

I did turn this setting right down though, as I found it often overwhelmed the ABS effect as it is always active. Having a big distinction between effects is really crucical to enhance any performance boost.

Settings such as the ABS, TC and brake threshold are all performance-enhancing effects. Over time, these should help improve your consistency as you’ll be able to feel the limit of your braking and throttle inputs in real-time, rather than relying on a flashing ABS light on your dash or steering wheel.

Do the mBooster active pedals make you faster?

One key question is, did these mBooster pedals make me faster? The honest answer is no. However, there is a big caveat with that: I have been racing with the Simucube ActivePedals for over a year. During my transition from a load cell pedal to the Simucube ActivePedals, I definitely did notice an improvement in my consistency, which led to improved lap times in almost all scenarios.

If I had never used an active pedal before switching to the mBooster. I am almost certain that I would have found the same performance and consistency gains as I did when I first switched a year ago.

Issues

No review is complete without discussing any potential problems that I have. While the mBooster pedal is incredibly impressive, there are some small areas where improvements could have been made.

Lack of power button

The first is the notable lack of a power button or standby mode. If you’ve ever raced with an ActivePedal, you’ll know that the internal motor makes a soft humming or whirring sound, even when the pedal is not in use. This is normal across active pedals, however, Simucube factored this in by adding a power button to the rear of each pedal.

For sim racers like myself, who often have my sim racing setup powered on, even while I’m not racing, the power button lets me switch off my Simucube pedal and stop this background noise while I’m recording audio or not using the rig.

With the mBooster pedal, I constantly found myself pulling the power cable out during these moments away from the track. If I’m filming, recording or just working at my desk in the same room, it’s not ideal to have a constant humming noise coming from the pedal. The lack of a power button served as a small, but constant point of frustration with the mBooster pedal.

Mounting trouble

I did mention it before, but mounting these pedals at the rear is incredibly difficult due to the lack of space. Mounting from the bottom up on a sim rig, which features a pre-drilled pedal plate, may be easier.

However, mounting from the top down to the CRP2 pedal plate as intended is a test of your flexibility and patience. While mounting my pedal, I scuffed the rear of the motor housing due to this lack of space, which did genuinely annoy me given that I’ll probably be using this pedal for years to come.

Is the MOZA mBooster pedal worth buying?

With a similar range of effects as a pedal double its price, the mBooster is certainly going to make a big splash in the premium sim racing space. This is a piece of hardware that is targetted solely at sim racers who are looking to maximise their immersion and performance, rather than those jumping into sim racing for the first time.

The pedal itself feels every bit as smooth as its premium competitors, and the ability to instantly switch how your pedal behaves and feels is so valuable. The force feedback effects themselves are highly configurable, and really go a long way towards matching the benchmark that Simucube has laid down.

The key omission of some effects, such as G-force, would typically be a bigger problem. However, due to the software-controlled nature of the mBooster active pedal, new effects can be added at any time.

While I would never recommend buying any product based on its future potential, the sky really is the limit with the mBooster, as MOZA can add new effects, tinker and fine-tune current effects throughout its shelf life.

Simucube may have pioneered the active pedal. However, MOZA’s lower price has opened this style of sim racing active pedal to many more sim racers.
