Assetto Corsa Competizione (ACC) can feel incredible on direct drive, but it’s also easy to make it feel heavy, harsh, or “dead” if you run too much gain or too much damping. With an Asetek wheelbase, you have enough detail that you can keep the setup clean and still feel everything you need.
This guide gives you a safe baseline and, more importantly, a method to tune ACC without losing tyre detail.
Start with a clean baseline (then tune one thing at a time)
Use this as a starting point in ACC:
| Setting | Baseline | Why |
|---|---|---|
| Gain | 60–70 | Enough strength without constant clipping |
| Minimum force | 0 | Direct drive doesn’t need it |
| Dynamic damping | 80–100 | Helps stability without killing detail |
| Road effects | 0–5 | Keep “effects” subtle; let physics do the work |
Important: these numbers are a baseline, not a universal truth. Your wheelbase strength, your rig rigidity, and even your seat posture change what feels “right”.
The ACC method: tune for tyre load, not for kerb drama
Fast ACC driving is mostly about reading tyre load changes. Your wheel should tell you:
- when the front tyres load up in long corners,
- when the front is starting to wash wide (early understeer),
- when kerb hits will destabilize the rear.
If your wheel mainly tells you “BANG” over kerbs, lower gain and reduce effects. If the wheel is smooth and you can feel tyre load in a long corner, you’re on the right track.
How to check clipping in ACC
Watch the force feedback meter. If it’s red all the time, you’re clipping and masking detail. Reduce gain until only the biggest hits flirt with the limit.

Why your cockpit changes ACC feel more than you think
ACC’s tyre load detail lives in small steering changes. On a flexible rig, those micro-forces get absorbed. Many people respond by increasing damping or gain, which makes the wheel heavier but not necessarily better.
A rigid, adjustable cockpit lets you keep filters low and detail high:
- SIMGASM Club rig works great for most direct drive builds.
- SIMGASM Sport rig adds extra adjustability and a cleaner build.
- SIMGASM Pro rig is the “no compromise” tier if you want maximum headroom (and it’s great if you plan motion later).
Recommended SIMGASM build for ACC on Asetek
- Wheelbase: Asetek La Prima 12 Nm wheelbase or Asetek Forte 18 Nm wheelbase (Invicta if you want maximum headroom: Asetek Invicta 27 Nm wheelbase)
- Rig: SIMGASM Sport rig (sweet spot) or SIMGASM Pro rig (flagship)
- Wheel mount: SIMGASM Front Wheelmount + Asetek front wheelmount bracket
- Seat: Core Recline seat for endurance comfort, or Atlas GT seat for a locked-in GT posture
Don’t forget pedals: ACC is a trail-braking sim
Choosing the right pedal set and mounting it correctly matters as much as wheel settings. If you’re still deciding, read Asetek pedals compared. If you already own pedals, use the Asetek pedal mounting guide.
ACC rewards a stable brake release. If you’re fighting the brake pedal (or your heel slides), it’s hard to be consistent.
- Pedals: Asetek La Prima pedals or Asetek Forte S-Series pedals
- Heel support: SIMGASM heelrest
- Seat stability: Core Recline seat (comfort) or Atlas GT seat (locked-in)
Visual stability helps steering feel
If you run triples, a stable monitor solution makes it easier to judge slip angle and kerb strikes. Consider a freestanding stand like Apex freestanding triple monitor stand to keep screens solid even if you later add tactile or motion.
