Active pedals are one of the biggest changes happening in sim racing hardware. Instead of one fixed pedal feel, an active pedal can simulate different brake and throttle characteristics, adjust force curves, and give you a very repeatable reference—when it’s set up correctly.
This guide covers the MOZA mBooster active pedal: who it’s for, how to set it up safely, and why your cockpit matters more than ever.
Who should (and shouldn’t) buy an active pedal
An active pedal makes the most sense if:
- You drive multiple car types and want different pedal feels without rebuilding hardware.
- You care about repeatability and consistent muscle memory.
- You already have (or plan) a stable cockpit that won’t move under heavy braking.
It’s usually not the first upgrade for a beginner. Most beginners get more value from a good load cell set (like MOZA CRP2) and a stable rig first.
Safety first: what changes with active hardware
Active pedals can produce strong forces. Treat it like real equipment:
- Mount it to a rigid pedal platform.
- Keep the pedal area clear during calibration.
- Increase forces gradually—comfort and control come before “realism.”
Rig requirements: why a flexible cockpit ruins the experience
If your rig flexes, your active pedal settings become meaningless. You’ll feel movement in the cockpit instead of movement in the pedal. That’s why we recommend:
- SIMGASM Sport for most active-pedal builds (stiffness + internal cable passthroughs).
- SIMGASM Pro if you want maximum stiffness for heavy braking and a true “buy once” cockpit.
Add a consistent foot reference like the SIMGASM heel plate so your feet return to the same position every time.
Setup checklist (the practical version)
- Mount the pedal securely and confirm nothing shifts under load.
- Run calibration and verify the full range is recognized.
- Start with a conservative force profile and build from comfort.
- Match your seating position: correct seat distance and brake leg support is essential.
- Test in one sim first before you create multiple profiles.
Seat and posture: active pedals expose bad ergonomics
With stronger braking forces, your seating position matters more:
- Your seat should support your thighs so you can brake without lifting your hips.
- Your knee should be slightly bent at full brake—no locked legs.
- Your pelvis should stay stable; if you slide, your braking will never be consistent.
If you want comfort without a bucket seat, consider the Core Recline seat. For a locked-in race position, the Atlas GT seat is a great match.
How to think about pedal “feel” settings
Instead of chasing “real car feel,” chase a repeatable reference:
- Choose a force curve you can repeat under pressure.
- Set a firm end-stop so you have a reliable peak braking point.
- Keep it comfortable: endurance consistency beats one fast lap.
