The short answer
For most sim racers, a direct drive wheelbase in the 9 to 15 Nm range is the sweet spot. It has enough strength to deliver detailed force feedback without clipping, and it works on most rigid cockpits. Go higher if you want maximum headroom and you have a chassis that can handle it. Go lower if you're on a budget or racing from a desk.
The rest of this guide explains why, and how to pick the right number for you.
What torque actually does
Torque, measured in newton-metres (Nm), is how hard the motor can turn the wheel. But you'll rarely run a wheelbase at 100%. Most drivers set their force feedback well below the maximum because full strength is tiring and unnecessary.
So why pay for more? Headroom. A stronger motor can reproduce big forces (a kerb strike, a slide, a crash) without running out of strength, while still having plenty left over for the small details: road texture, tyre load and the moment the front starts to slip. When a weaker base hits its limit, the signal "clips" and you lose that detail exactly when you need it.
Torque tiers, with examples we stock
Entry direct drive (5 to 9 Nm)
A huge step up from gear or belt-driven wheels. Great for desk mounts, lighter wheel stands and newer drivers.
- Fanatec CSL DD: 5 Nm
- Simagic Alpha EVO 9 Nm version
Mid-range (12 to 18 Nm)
The best value for most people. Strong enough for GT cars and formula cars, and the level many serious sim racers settle on.
- MOZA R12 V2: 12 Nm
- Simagic Alpha EVO 12 and 18 Nm versions
- Simucube 3 Sport: 15 Nm
- Asetek Forte: 18 Nm
High-end (25 Nm and up)
Maximum headroom and the most detailed, unclipped feedback. These need a rigid aluminum profile cockpit.
- Simucube 3 Pro: 25 Nm
- MOZA R25 Ultra: 25 Nm
- Asetek Invicta: 27 Nm
Four questions to pick your number
1. What are you mounting it to?
This matters more than most people expect. A powerful wheelbase on a flexible desk or folding stand will shake the whole setup, and the flex soaks up the detail you paid for. If you're going above about 12 Nm, plan on an aluminum profile chassis.
2. What do you drive?
GT, touring and road cars benefit most from smooth, detailed feedback, which any good mid-range base delivers. Formula cars with high downforce produce heavier steering at speed, so extra headroom helps. Rally and drift reward fast, strong responses.
3. How long are your sessions?
If you do long endurance stints, you'll probably run lower force anyway. That's another reason a mid-range base is often enough.
4. What's your total budget?
The wheelbase is only part of the cost. Budget for the wheel rim, pedals and a rigid cockpit too. A balanced setup (mid-range base, load cell pedals, solid rig) usually feels better than a top-tier base on a weak rig.
Our recommendation
- First direct drive, desk or wheel stand: 5 to 9 Nm
- Most sim racers on a proper cockpit: 12 to 18 Nm
- Want the best and have a rigid rig: 25 Nm and up
