Moza bases can feel fantastic in Assetto Corsa, but only if you set up your “signal chain” correctly. The goal is not maximum strength. The goal is maximum usable information: tyre grip building, slip starting, kerb strikes, and steering load changes that help you drive consistently.
This guide gives you starting-point settings for Moza wheelbases and a workflow to tune them for any car. Use it as a baseline, then adjust based on your preference and your hardware (wheel rim weight, mounting stiffness, and rig rigidity).
Step 0: mount stiffness decides how good your FFB feels
If your wheel deck flexes, your hands feel “mush” even with perfect settings. For Moza bases, a rigid cockpit and a solid wheel mount are the difference between “good” and “wow”.
- Use a stable rig such as SIMGASM Club simulator or SIMGASM Sport simulator.
- Match the mounting style with front wheel mount or bottom wheel mount depending on your base and ergonomics.
Moza Pit House baseline settings (starting point)
These values are designed to keep the wheel calm and detailed. They are not “the one true answer”; think of them as a clean baseline.
| Setting | R5 bundle | R9 / R12 | R21 / R25 | Why it matters |
|---|---|---|---|---|
| Max torque | 100% | 100% | 100% | Keep the wheelbase “honest”; control final strength in game. |
| Steering angle | 900° | 900° | 900° | Use car-specific rotation via soft lock / in-game rotation. |
| Damping | 10 | 8 | 6 | Reduces oscillation and calms the wheel without killing detail. |
| Friction | 6 | 4 | 3 | Adds “weight” around centre; too high makes the wheel feel dead. |
| Inertia | 10 | 8 | 6 | Controls how quickly the wheel changes direction; lower feels more “snappy”. |
| Wheel spring | 0 | 0 | 0 | Let the sim generate forces; spring often feels artificial. |
| Road sensitivity | 4 | 3 | 2 | How much “texture” you feel; high values can mask tyre slip. |
Assetto Corsa in-game baseline settings
Start here, then fine-tune per car:
| Assetto Corsa in-game setting | Baseline | Notes |
|---|---|---|
| Gain | 60–75% | Lower if you see clipping on kerbs or high-speed corners. |
| Filter | 0–3% | Use the lowest value you can tolerate; filtering hides detail. |
| Minimum force | 0% (DD) / 2–5% (R5) | Only needed if centre feels “empty”. |
| Kerb / Road / Slip effects | 0–15% | Keep these subtle; the physics FFB is more important than effects. |
| Enhanced understeer effect | Off (start) | Turn on only if you struggle to feel front grip loss. |
How to tune in 5 minutes (the workflow)
- Pick one reference car and track (e.g., a GT car on a track with kerbs and one fast corner).
- Drive 3 laps and watch for clipping: if forces “flatline” on kerbs or long corners, lower in-game gain by 5–10%.
- Fix oscillation (wheel shakes on straights): add a little damping (Pit House) before adding a lot of in-game filtering.
- Restore tyre slip feel: reduce road sensitivity/effects if everything feels like constant vibration.
- Save the preset as your “AC baseline” and only tweak gain per car category.
Wheel rotation tips (don’t guess)
Assetto Corsa feels best when rotation matches the car. Keep Pit House at 900° and manage the final rotation with in-game settings/soft lock. If you are unsure, read: Steering angle guide: wheel rotation, soft lock and car types.
Recommended Moza gear from the SIMGASM shop
- Moza R9 wheelbase: the sweet spot for detail and strength.
- Moza R12 wheelbase: more headroom for high-downforce cars and heavy kerbs.
- Moza R21 wheelbase or Moza R25 wheelbase: for maximum authority and lower in-game gain (less clipping risk).
- Wheel rims: Moza KS wheel, Moza GS V2P wheel, Moza FSR2 wheel.
Recommended SIMGASM gear for this guide
- Entry level: SIMGASM Hobby simulator for a clean first rig foundation.
- Most universal: SIMGASM Club simulator with a stiffer 80x40 profile for almost any wheelbase/pedal set.
- Best for frequent tweaking and cable routing: SIMGASM Sport simulator with built-in pass-through routing for tidy builds.
- Flagship: SIMGASM Pro simulator for maximum rigidity and adjustability with high torque and heavy braking.
- Comfort option: SIMGASM Core Recline seat if you don’t want a fixed bucket.
- Bucket options: SIMGASM Atlas GT seat for GT-style driving, or SIMGASM Atlas Formula seat for a more laid-back formula/hypercar position.
- Adjustability: dual locking slider set for quick driver changes.
- Triples: Apex freestanding triple monitor stand for a stable screen reference, or Core integrated triple monitor stand if you prefer an integrated look.
- VESA alignment: VESA mounting bracket to make mounting cleaner across VESA sizes.
If you are unsure what fits your hardware, SIMGASM support can help you match mounts, bolt patterns and upgrade paths before you buy.
Quick troubleshooting
- Feels too heavy: lower in-game gain first, not Pit House torque.
- Feels too “buzzy”: reduce road sensitivity and effect sliders before adding heavy damping.
- No detail on centre: reduce friction/damping slightly; avoid high filtering; consider a small minimum force only on lighter bases.
