How to Choose the Right Wheelbase

It is always a question we get, why get a certain wheelbase. We always tell people to get what your budget can afford. If you have a sturdy Rig you can get a wheel with more NM of toque. This allows you to have a more realistic feel throughout any car, track, wheel, or game. Look at this as the base to your system. All the accessories and different wheels can be added later and you will be able to get the full potential out of them. Hopefully the below lists and points help you narrow in on what works for you. Only doing Go Motorsports Legends on Iracing on a desk? That's awesome, and extremely fun! You don't need a R25 Ultra for a full experience. An R5 would be fine and a R9 or R12 Would be at the top end for your current needs.    

When choosing a direct-drive wheelbase, consider these key factors:

1. Force Feedback & Power (Nm)

  • Higher torque (Nm) = stronger and more realistic force feedback. If you want precise, powerful sensations and plan to use serious sims (like iRacing, Assetto Corsa Competizione), pick a wheelbase with more torque.
  • Lower torque is still fine for casual racing or smaller rigs.

🎯 2. Skill Level & Future Needs

  • Beginners / casual players: Smaller units are easier to control and gentler on your arms.
  • Experienced / competitive racers: Consider more powerful models — they reveal subtleties in traction and car behavior.
  • Plan for the future: a stronger wheelbase now can delay the need to upgrade later.

🧱 3. Rig or Desk Mount

  • Powerful wheelbases exert a lot of force. Make sure your rig or desk clamp can quietly handle the torque (especially 12Nm+ and above). Smaller units are lighter and easier to mount.

🛠️ 4. Platform Compatibility

  • Most MOZA units are PC-focused, though some like the R3 have Xbox versions. Always check compatibility with your platform before buying.

📊 5. Extras & Ecosystem

  • Software features (like MOZA Pit House) let you fine-tune force feedback, steering curves, button mappings, and more — a great bonus.
  • Consider whether you want a bundle with wheel & pedals included or just the base.

Quick Tips Before You Buy

✅ Match torque to your rig: Desk setups may struggle with high torque.
✅ Bundles save money: If you’re starting fresh, a wheelbase + wheel/pedals bundle can be more cost-effective.
✅ Future proofing: If you expect to stick with sim racing for years, lean toward a stronger model you won’t outgrow quickly.

Why have a wheelbase with more NM torque? 

1️⃣ Stronger, more realistic force feedback

Higher torque lets the wheel accurately reproduce real steering loads:

  • Heavy steering in high-downforce cars
  • Big hits over curbs
  • Violent snaps when the rear steps out

Lower-torque bases have to compress these effects so they don’t clip (max out). Higher Nm keeps everything intact.

2️⃣ More detail without clipping

Clipping happens when the wheel hits its max force and everything feels the same.

With more Nm:

  • Small details (road texture, tire slip) stay subtle
  • Big moments (lockups, curb strikes) stay big
  • You feel layers of feedback, not just noise

This is one of the biggest quality upgrades when moving up in torque.

3️⃣ Faster, more precise corrections

A higher-torque motor responds quicker and with more authority:

  • Catch slides sooner
  • Feel the car rotate before it spins
  • Make smoother counter-steering inputs

That translates directly to confidence and consistency, especially in competitive racing.

4️⃣ Better performance at lower settings

This surprises a lot of people 👇
Even if you only use 8–10 Nm, a 15–20 Nm wheelbase will feel better doing it.

Why?

  • The motor isn’t working near its limit
  • Less heat, less fade
  • Smoother, cleaner feedback
  • Think of it like a big engine cruising instead of a small engine redlining.

5️⃣ Essential for heavier wheels & real-world rims

If you use:

  • Formula rims with metal construction
  • GT wheels with lots of buttons
  • Real steering wheels + quick releases

You need extra torque just to move the mass without dulling feedback.

6️⃣ More immersive = less guessing

With enough torque, you can feel:

  • Front tires starting to wash
  • Rear grip fading under throttle
  • Weight transfer mid-corner

That means you drive by feel—not by reacting late or staring at the screen.

Quick torque guidelines (real-world use)

  • 3–5 Nm → Entry level, desk setups
  • 8–10 Nm → Solid realism, great for most racers
  • 12–15 Nm → Sweet spot for immersion + detail
  • 18–25 Nm → Serious sim racers & pro-level feel

⚠️ Important: more Nm also means you need a sturdy rig, not just a desk.

Bottom line

You want more Nm of torque because it gives you:

  • ✅ Better realism
  • ✅ More detail
  • ✅ Less clipping
  • ✅ Faster reactions
  • ✅ A wheelbase you won’t outgrow
