MOZA R9 (RS V2) vs CAMMUS C12 — Battle of the Compact Powerhouses

ByNeo Sphinx

Today we’re diving into a head-to-head comparison between two powerful compact wheelbases — the MOZA R9 (v2) paired with the RS V2 steering wheel, and the CAMMUS C12.

Both are direct drive systems aimed at sim racers who want a compact yet immersive driving experience.
But with differences in torque, build, and eco-system, which one delivers the better overall value? Let’s find out.

⚙️ Hardware Overview

The MOZA R9 v2 brings a few key upgrades over the original v1 model:

  • An RJ port that allows direct connection of MOZA pedals to the wheelbase
  • Compatibility with the MOZA ES steering wheel

The CAMMUS C12, on the other hand, has received firmware updates but no major hardware changes since its release.

Technically, these are two very different beasts:

  • R9 uses a traditional servo motor, delivering up to 9 Nm of torque.
  • C12 uses an external rotor servo motor, generating a constant 12 Nm torque — with higher peaks possible.

💡 Ideally, this comparison would pit the C12 against the MOZA R12, but due to availability and cost (about €100 more), we’re comparing the R9 and C12 as two similarly positioned packages.

🧩 Design & Build Quality

Both bases feature metal housings and a solid, premium construction. Neither shows any structural weaknesses, but their designs reflect different philosophies.

  • MOZA R9 feels minimalistic, clean, and industrial.
  • CAMMUS C12 looks slightly more aggressive with sharper lines and a smoother finish.

Build quality overall is excellent on both, though the MOZA’s quick release system gives it an extra edge in daily usability — something completely absent on the C12.

🛞 Steering Wheels — Feel & Function

🧠 Layout & Controls

  • C12 Wheel: 30 cm diameter, smooth faux leather finish
  • MOZA RS V2 Wheel: larger 33 cm diameter, wrapped in real leather

Both offer a similar control layout, but the C12 includes four extra rotary encoders, giving it a slight advantage in customization.

Each wheel features:

  • Mechanical push buttons with LED backlighting
  • Rotary encoders that turn smoothly and click precisely
  • Rev lights across the top
  • Carbon fiber paddles, with the RS V2’s being slightly adjustable and including dual clutch levers

When it comes to tactile quality, the RS V2’s genuine leather and forged carbon fiber detailing elevate its premium feel, while the C12 delivers impressive craftsmanship for its price point.

💻 Software & Customization

Both ecosystems include robust tuning software — but MOZA takes the win for presentation and usability.

The MOZA Pit House software:

  • Offers presets for GT, Sport, and F1 profiles
  • Provides intuitive adjustment for gain, damping, road effects, and inertia
  • Makes it easy for beginners to get solid results quickly

The CAMMUS software is functional but more basic. It lacks the preset flexibility and polish of MOZA’s interface.

✅ Winner for software & ease of tuning: MOZA R9

🏎️ Driving Impressions

On-track, both deliver convincing feedback — detailed, smooth, and engaging.

  • MOZA R9: Excellent detail reproduction but starts to feel underpowered in heavy corners or high downforce cars.
  • CAMMUS C12: Noticeably stronger, especially in high-load situations and when fighting lateral forces. The extra torque translates into a more dynamic and intense drive.

In ACC, the C12 clearly feels more powerful, but both bases maintain a similar level of detail and smoothness.

🚗 BeamNG Drive

BeamNG’s feedback system is lighter and less detailed overall.
Here, the R9 feels just as good as the C12, since the game doesn’t fully utilize the C12’s additional torque.

For casual or open-road driving, both are equally satisfying, though the C12’s wheel controls make it slightly easier to navigate menus and camera views without touching a keyboard.

🔄 Ecosystem & Compatibility

This is where the two diverge significantly.

  • CAMMUS: Offers just two wheel rims — a GT wheel and a larger round one.
  • MOZA: Features an extensive and growing eco-system, covering:
    • GT and Formula wheels
    • A truck wheel and indicator stalks
    • Pedals, shifters, handbrakes, and dashboards

MOZA is currently the most complete eco-system for sim racers who enjoy multiple driving styles — from GT and rally to trucking or casual cruising.

✅ Winner for ecosystem: MOZA R9

💰 Price Comparison

The C12 delivers more power for less money, while the R9 offers better modularity and ecosystem value.

🏆 Conclusion

Both of these wheelbases deliver fantastic performance for their price, but they cater to different drivers.

  • 🧭 MOZA R9 (RS V2):
    Ideal for sim racers who value ecosystem expandability, software polish, and premium materials.
  • ⚙️ CAMMUS C12:
    Perfect for those wanting raw power, simplicity, and great value without the need for constant hardware swaps.

💬 In summary:
If you want one wheel for everything and love fine-tuning — go MOZA.
If you want maximum torque per euro and simplicity — the CAMMUS C12 is unbeatable.

Either way, you’re getting high-quality, compact direct-drive performance that will transform your sim racing experience.
