iRacing rewards consistency. That means your force feedback should be predictable, not dramatic. With Simagic wheelbases, the biggest win is getting a “clean baseline” that avoids clipping and stays comfortable for long stints.

This guide gives you a practical setup workflow for iRacing with Simagic, plus a few tuning branches for GT, prototypes and formula cars.

Step 0: make sure the cockpit is not the weak link

Before you touch software, check this:

• The wheelbase is mounted rigidly (no plate flex, no loose bolts).
• Your seat and pedals don’t move relative to each other under braking.
• Cables are routed so nothing tugs when you steer.

If you’re building from scratch, SIMGASM Club cockpit (C80) is a great foundation for Simagic in this torque class, and SIMGASM Sport cockpit (C120) / SIMGASM Pro cockpit (C160) are ideal if you’re running higher torque or planning upgrades.

Step 1: set wheel rotation correctly

1. Set a sensible max rotation in SimPro Manager (900° is a common default).
2. In iRacing, calibrate the wheel and pedals.
3. Let iRacing apply soft lock per car where available.

Step 2: set Wheel Force correctly so Auto FFB works

In iRacing, the Wheel Force value should match your base’s maximum torque class (for example: 10Nm, 15Nm, 23Nm). Then:

1. Go on track.
2. Use iRacing’s Auto force feedback strength (usually in the black box).
3. Drive a few laps and check if big kerbs or crashes cause constant clipping.

This workflow is explained in more detail in the clipping guide.

Step 3: build a stable SimPro Manager baseline

Start with a “minimal filter” philosophy:

• Keep smoothing low unless the wheel feels grainy on straights.
• Use small damper/friction only to solve oscillation or an overly light center.
• Don’t chase feel with huge filters if the real issue is cockpit flex.

Branch A: GT cars (GT3, GT4, GTP)

• Prioritize weight build-up and steady mid-corner feel.
• If kerbs feel too violent, reduce “detail” first, then add a touch of slew control.
• If the wheel oscillates on straights, reduce rotation speed slightly and add a small damper.

Branch B: prototypes and high downforce

• These cars can create big spikes. Keep your tuning calm.
• Use headroom instead of raw gain: it’s okay to run lower strength while keeping detail.
• Rig stiffness matters a lot. If the wheel deck twists, the car will feel nervous.

Branch C: formula cars

• Most formula drivers prefer faster response and less damping.
• Consider a slightly lower max rotation and let the car’s steering ratio do the work.
• If the wheel feels too “twitchy”, don’t over-smooth. Fix seating distance and rotation speed first.

Ergonomics tip that improves pace immediately

If you’re reaching for the wheel, you’ll over-correct and tire faster. A cockpit that adjusts easily makes you faster because you can set a repeatable posture.

• SIMGASM Core Recline seat for comfort during long iRacing sessions.
• SIMGASM Atlas GT seat if you want a locked-in braking posture.

• Entry: SIMGASM Hobby cockpit (C40) if you want the lowest price while still getting a real aluminium rig.
• Most popular: SIMGASM Club cockpit (C80) for “buy once, upgrade later” stiffness.
• High torque / motion: SIMGASM Sport cockpit (C120) or SIMGASM Pro cockpit (C160) depending on torque and how hard you brake.
• Comfort seat option: SIMGASM Core Recline seat if you don’t want a fixed bucket seat.
• Bucket seat options: SIMGASM Atlas GT seat for GT driving position, or SIMGASM Atlas Formula seat for a more laid-back formula/hypercar position.
• Mounting: seat bracket set makes seat install and positioning easier on a profile rig.
• Monitors: integrated triple monitor stand if you want an integrated, space-saving setup, or freestanding triple monitor stand if you want the screen isolated from vibrations and future motion upgrades.
• VESA hardware: VESA mounting bracket set for clean, rigid mounting (especially helpful for triples).
• Wheelbase mounting: wheel mount base set + front wheel mount when you want a clean, rigid wheel deck.
• Alternative mounting: bottom wheel mount and large side plates / small side plates for different base/mounting styles.
• Shifter/handbrake: shifter and handbrake mount + universal peripheral deck for rally/drift layouts.
• Ergonomics add-ons: keyboard swivel mount, heelrest and heel plate for a more “finished” cockpit feel.
