Simagic wheelbases are popular because they deliver clean detail without feeling “digital”. But the best Simagic setup is not just a software profile. It is a whole chain: wheelbase → mount → cockpit rigidity → seating position → monitor and FOV.
This guide gives you baseline settings you can copy as a starting point, then a simple workflow to refine them for iRacing and Assetto Corsa Competizione (ACC) without chasing your tail.
Step 1: make sure your mount is not the weak link
Before touching filters, remove flex. If your wheel deck moves under load, the force feedback signal gets “blurred” and you will compensate by turning the wheelbase up until it feels heavy, not detailed.
- Entry to mid torque (up to ~12 Nm): a rigid cockpit like the SIMGASM Club simulator is a strong foundation for most hardware.
- High torque (15 Nm and up) or frequent endurance sessions: choose the SIMGASM Sport simulator or SIMGASM Pro simulator for maximum stiffness and adjustability.
- Mounting style: pair your rig with the right wheel mount: front wheel mount, bottom wheel mount or a side solution depending on your base and plates (large side plate).
Step 2: choose a clean “baseline” in SimPro Manager
Different Simagic models have different max torque, but the tuning logic is the same: keep the wheelbase stable, keep filters light, and let the sim provide the detail.
Baseline profile (starting point):
| Setting | Suggested starting value | Why it matters |
|---|---|---|
| Overall strength / max torque | Set to your wheelbase max, then tune in game | Gives full headroom; you control real driving force in the sim to avoid clipping. |
| Mechanical damper | 5–15% | Stability on straights without killing micro detail. |
| Friction | 0–10% | Adds “weight”; too much hides tyre slip signals. |
| Inertia | 0–10% | Controls how quickly the wheel changes direction; keep low for responsiveness. |
| Smoothing / filter | Low (1–3 steps) | Removes grain, but too much makes the wheel feel numb. |
Tip: If you feel oscillation on the straight, increase damper slightly before adding heavy smoothing. Smoothing can hide the very detail you bought a direct drive wheel for.
Step 3: iRacing settings that work with Simagic
In iRacing, the key is setting the correct wheel force and then choosing a strength that does not clip in your fastest corners.
- Calibrate wheel and pedals first (especially if you changed steering angle).
- Set Wheel force to match your wheelbase max torque (example: 12 Nm wheelbase → 12 Nm wheel force).
- Use iRacing’s auto FFB as a start, then reduce 5–15% if you see frequent clipping.
- Keep iRacing’s extra damping minimal; do stability in SimPro Manager.
If you want a repeatable workflow, follow the clipping checklist in our guide below.
Step 4: ACC settings for a detailed but calm wheel
ACC can feel “busy” if your base is too sharp. Your goal is clear tyre load, not extra road noise.
- Gain: start around 60–75 and adjust down if you clip.
- Minimum force: usually 0 on direct drive.
- Dynamic damping: keep low; let the wheelbase do the damping.
- Road effects: low (0–10) so kerbs do not drown out grip detail.
Common problems and fast fixes
- Oscillation on straights: add 3–5% damper, reduce in game strength slightly, check that your rig does not flex.
- Feels heavy but not detailed: reduce friction/inertia, reduce smoothing, lower gain and increase wheelbase headroom.
- Kerbs feel like a jackhammer: reduce road effects and reduce overall gain before adding filters.
Recommended SIMGASM gear
- SIMGASM Club simulator (stable base for most DD wheels)
- SIMGASM Sport simulator (more adjustability and clean cable routing)
- Front wheel mount for direct drive bases
- Wheel mount base set (build the mount that fits your wheelbase)
- Atlas GT seat for long sessions
- Apex freestanding triple monitor stand for a clean sightline
