Asetek’s direct drive lineup is easy to understand on paper: La Prima (12 Nm), Forte (18 Nm) and Invicta (27 Nm). The trap is assuming the decision is only about torque.
In practice, the “right” wheelbase depends on three things:
- How you drive (smooth vs aggressive, sprint vs endurance, drifting vs precision)
- How you tune (high gain and soft filters vs lower gain and more headroom)
- How stable your cockpit is (rig flex can turn great detail into noise)
Quick comparison: La Prima vs Forte vs Invicta
| Wheelbase | Peak torque | Who it fits best | What you’ll notice |
|---|---|---|---|
| La Prima | 12 Nm | Most sim racers upgrading from belt/gear wheels, or anyone who wants a clean DD experience without going “extreme” | Clearer tyre detail, better counter-steer control, and enough headroom for most road/GT driving |
| Forte | 18 Nm | Drivers who want more calmness at the same on-hands force, heavier GT/prototype feel, or more room for filters without losing detail | More headroom, less clipping risk, more “weight” when you want it |
| Invicta | 27 Nm | Drivers who want maximum headroom, motion-ready builds, or very heavy steering with low in-game gain | Effortless strength reserve, extra smoothness at the same perceived force |
If you’re shopping on SIMGASM, you can jump straight to the wheelbases here: Asetek La Prima 12 Nm wheelbase, Asetek Forte 18 Nm wheelbase and Asetek Invicta 27 Nm wheelbase.
What “more torque” really gives you (when you don’t run max strength)
Many experienced drivers don’t run a 18–27 Nm base at 18–27 Nm. They run it at a comfortable level and use the extra range as headroom.
- Less clipping: spikes over kerbs and compressions can still fit inside the wheel’s range.
- More texture at lower gain: you can reduce global gain and still keep detail.
- A calmer wheel: the wheel can feel smoother because it isn’t always “at the limit”.
That’s why a 12 Nm wheelbase can feel amazing for one person, while another prefers a 18 Nm base even at similar on-hands strength.
The overlooked part: your rig decides how much detail you can actually use
Direct drive is brutally honest. If your cockpit flexes, you often compensate by cranking damping, friction, or smoothing. That makes the wheel feel “safer” but can hide the information you paid for.
This is where an adjustable aluminium profile cockpit helps. With SIMGASM aluminium rigs, you can:
- mount the wheelbase rigidly (so detail stays in the steering, not the frame),
- adjust wheel height/angle and pedal distance precisely (so you can drive longer without fatigue),
- add accessories later (shifter, handbrake, button box, stream deck, motion, tactile) without rebuilding.
Which SIMGASM rig tier matches each Asetek wheelbase?
Here’s a practical “no overthinking” pairing that works for most people:
- La Prima (12 Nm): SIMGASM Club rig is a great match for most builds; choose SIMGASM Sport rig if you want more adjustability and cleaner cable routing.
- Forte (18 Nm): SIMGASM Sport rig is the sweet spot for rigidity + adjustability; go SIMGASM Pro rig if you want maximum stiffness, future motion, or heavy endurance usage.
- Invicta (27 Nm): SIMGASM Pro rig is the sensible option if you want to use the headroom without adding filters to hide flex.
For mounting flexibility, start with SIMGASM Wheelmount base set and add a dedicated solution like the SIMGASM Front Wheelmount or the Asetek front wheelmount bracket when you want a front-mount style setup.
Recommended SIMGASM setup (clean and upgradeable)
- Rig: SIMGASM Club rig (most users), SIMGASM Sport rig (best all-round), or SIMGASM Pro rig (flagship headroom)
- Seat: Core Recline seat for comfort and long stints, or Atlas GT seat/Atlas Formula seat for a locked-in race posture
- Monitor solution: Core integrated triple monitor stand for an all-in-one clean build, or Apex freestanding triple monitor stand to keep screens stable even if you add motion later
One last note: SIMGASM rigs are made to be modular (and available in multiple colours). If you’re unsure which tier, mount or seat configuration fits your body and hardware, our support and sales team can help you pick the cleanest path without overspending.
