MOZA mBooster vs Simucube ActivePedal Pro

What this comparison can tell you

My mBooster review compared its feel with the Simucube experience I already knew. In the separate Pro review, I tested the Pro as a brake alongside my Ultimate and found the experience effectively indistinguishable at my settings. Those findings support this buying discussion, but they do not amount to a fresh, controlled mBooster-versus-Pro test on identical firmware.

That distinction is especially important for the MOZA: I used beta Pit House software in March 2025. I am preserving the strengths and drawbacks I experienced, rather than assuming later updates either fixed everything or changed nothing.

Both made software-adjustable braking useful

The shared attraction was the ability to change the force curve, travel and resistance without rebuilding a spring or elastomer stack. A short, firm brake and a softer, longer response could become different profiles instead of different afternoons under the rig.

The mBooster delivered a strong, consistent response when I applied and released pressure. Simucube felt a little smoother and more accurate to me, but the MOZA still gave me confidence while braking. That smaller refinement difference did not cancel out the usefulness of the core experience.

My argument for either product is about feel, adjustment and feedback. I did not establish a controlled lap-time improvement, so I would not buy one expecting a guaranteed performance gain.

Haptics were the more meaningful compromise

In the mBooster test, ABS vibration was milder than I wanted even with the effects turned up. I could feel it, but it did not have the clarity and strength I associated with my Simucube pedals. Tyre lock-up feedback was useful, particularly the way it built as I approached a lock-up.

The Pro review, by contrast, highlighted ABS as one of the benefits I enjoyed most. If detailed feedback is your main reason for entering this category, I would give that distinction more weight than I would for someone chiefly interested in adjustable resistance.

I also heard the mBooster fan above my PC fans while sitting in the rig. MOZA’s current page makes its own quiet-operation claim; that does not replace my observation, and I did not conduct a comparable sound-level test of both products.

Physical fit still comes before software flexibility

The mBooster’s attachment points were awkward to align with my ASR Pro pedal plates. Its length, extension-plate arrangement and footplate position all deserved planning. I liked the slight curve of the face but wanted it wider, and my test unit did not offer the face-height adjustment I had on the Simucube.

I fitted the ActivePedal Pro directly to my chassis and used a separate heel rest. That worked for me, but the Pro was still a large pedal. A successful installation on my rig does not establish fit on every pedal deck.

The mBooster connected directly to the PC; it did not require a MOZA wheelbase. The Pro used Simucube Link and its own power supply. Compare the full connection and mounting package, particularly when adding an active pedal to equipment you already own.

Compare complete setups, not old headline prices

My March 2025 review discussed US$799 for one mBooster and US$999 for the bundle with a CRP2 throttle, baseplate and extension plate. I contrasted that with a Pro priced at just over US$1,700 before the required Link Hub. Those were the figures behind my original value judgement, not current quotes.

A fair comparison today includes the throttle you intend to use, connection hardware, mounting parts, taxes and shipping. If your existing passive throttle already suits you, replacing it can make the decision unnecessarily expensive.

I was less convinced by the mBooster as a throttle or clutch. My own two-active-pedal Simucube arrangement was a luxury I enjoyed, not a configuration I thought most people needed to copy.

Which would I choose?

I would consider the mBooster first for the adjustable active-brake experience, provided its physical fit and the compromises from my test were acceptable. At the original prices, I did not think everyone would find Simucube’s extra refinement worth the difference.

I would choose the Pro when its feedback, physical adjustment and the Simucube experience I preferred were the priority and the complete price fitted comfortably.

Either way, I would start with the brake. A well-chosen passive throttle keeps the purchase focused on the role where I found the clearest benefit.
