El elemento más importante que te une al coche virtual. Qué es, cómo funciona, por qué mejora el tiempo por vuelta… y cómo calibrarlo como un profesional.
FFB stands for Force Feedback — the technology that makes your steering wheel (and, in advanced setups, your pedals) physically react to the simulation: road texture, kerb strikes, weight transfer, and grip loss. If the wheel only steered, you would be driving blind; FFB is how the car "talks" to your hands.
/// Signal Path
Cómo funciona realmente la retroalimentación de fuerza
Every simulator runs a physics engine that calculates, hundreds of times per second, the forces acting on the virtual steering rack: tire grip, slip angle, suspension load, kerb impacts. That value travels down a chain before it reaches your hands:
01 · PHYSICS
Sim Engine
Calculates tire & steering-rack forces in real time.
02 · SIGNAL
FFB Output
Signal sent to the wheel base: gain × effects.
03 · MOTOR
Wheel Base
Converts the signal into torque on the shaft.
04 · DRIVER
Your Hands
Read grip, weight transfer & slides instantly.
Cualquier punto débil en esa cadena —una señal filtrada, un motor poco potente o una ganancia mal calibrada— destruye la información antes de que te llegue. Y en las carreras, la información es el tiempo por vuelta.
2 Nm → 32 NmThe torque spread across the current market: a Logitech G923 produces roughly 2 Nm; a Simucube 2 Ultimate peaks at 32 Nm — sixteen times the force. Everything between is a trade between price, detail and fatigue. (Manufacturer specifications)
333–360 HzWhere the signal is born: Assetto Corsa Competizione outputs its FFB at 333 Hz, iRacing at 360 Hz. Modern Direct Drive control loops run at 1000 Hz. A belt drive physically cannot track detail that arrives faster than its drivetrain can move. (Kunos/iRacing documentation, Simucube True Drive)
60–70%Where serious endurance drivers actually run their base strength — far below the peak the marketing page advertises. A wheel you wrestle for three hours hides the micro-signals that warn you the rear is about to go. Fatigue is the silent lap-time killer.
0% clippingThe only correct target on the FFB meter. When the trace flattens against the motor ceiling, peaks are being cut — and every clipped peak is grip information deleted before your hands receive it. Try the Signal Lab below to see it happen. (iRacing FFB black box; ACC HUD widget)

The orange dashed lines are your motor ceiling. When the red trace flattens against them, the peaks are cut — that's clipping, and every clipped peak is information your hands will never feel.

Esta lección sorprende a la mayoría de los conductores: una señal más potente no implica una mejor respuesta. Una señal calibrada de intensidad media, sin distorsión, supera siempre a una señal al máximo de potencia. Es mejor una señal en la que puedas apreciar los detalles que una con la que tengas que luchar.

How The Fastest Drivers Set Their FFB
FFB is not a strength contest — it is applied signal calibration. This is the method used at the top of iRacing and by real-world drivers who train on simulators.
Rule 01 · Zero Clipping
Calibrate with the meter, not by feel
Every serious sim has an FFB meter — the iRacing black box, the ACC HUD widget. Pros watch it on a representative corner (fast, loaded, kerbs) and lower gain until peaks stay out of the red. Guessing by feel always ends 20% too hot.
Rule 02 · Strength ≠ Detail
Enough torque to read, not to fight
Top endurance drivers run far below what their base can do — typically 60–70% of peak. A wheel you wrestle for 3 hours hides the micro-signals that warn you the rear is about to go. Fatigue is the silent lap-time killer.
Rule 03 · Linearity First
Base at 100%, scale in the game
Set the wheel-base software to its native, unfiltered output and do your scaling inside the simulator. Double-filtering (base damping + game damping + game filter) stacks latency and smears the exact detail you paid for.
Rule 04 · One Change At A Time
Tune like an engineer
Change a single value, run five consistent laps, judge one question: can I read the car earlier? If a setting makes the wheel heavier but the information later, it was a downgrade — no matter what the number says.
/// The Pedal Equation
FFB Talks To Your Hands. Who Talks To Your Feet?
/// Engineering note — the feedback loop has two ends
FFB is only half of the sensory loop in a race car. The wheel talks to your hands; the brake pedal must talk to your feet with the same fidelity — because the braking zone is where races are decided and where information arrives fastest. A pedal whose resistance drifts with heat or ages like a polymer sends your feet the same corrupted signal that clipping sends your hands: technically still connected, silently lying.
This is the engineering reason SRP® pedals are pneumatic: the opposing force your legs train against obeys a gas law instead of a wear schedule. Professional drivers preparing real races — Miguel Molina (2024 Le Mans overall winner), Daniel Juncadella (Daytona 24h & Spa 24h winner), Albert Costa (Le Mans class winner) — train on this hardware daily, and the haptic kit closes the loop entirely: ABS and traction-loss feedback delivered at the pedal, the moment the tires cross the limit. Full concept in Force Feedback in pedals: active vs passive.

/// Data, Not Immersion
Why FFB Wins (And Saves) Lap Time
FFB is not immersion — it is data. Through the wheel you feel the exact moment the front tires start to slide (understeer), when the rear steps out under throttle (oversteer), and how much grip is left in the contact patch before you ever see it on screen. Drivers who learn to read that language brake later, catch slides earlier, and stay consistent over a full stint.
In endurance racing — the discipline where professional teams validate our hardware — consistency over hours is worth more than a single heroic lap. As we explore in our racing telemetry guides, consistency relies on a flawless understanding of vehicle dynamics and hardware that translates your intent without degradation.
And once your hands are calibrated, close the loop: a mathematically correct FOV setting aligns what you see with what you feel — vision, hands and feet reading the same car at the same time.
/// Paddock FAQ
Force Feedback Questions
¿Qué significa « FFB »?
FFB son las siglas de «Force Feedback», es decir, las fuerzas que un simulador transmite a los mandos para recrear el comportamiento del coche virtual: adherencia, transferencia de peso, bordillos e impactos.
¿Qué es la retroalimentación de fuerza en un volante?
Un motor situado en el interior del eje de las ruedas aplica par al eje, reproduciendo la textura de la carretera, los golpes contra los bordillos, el subviraje y las colisiones. Las ruedas accionadas por engranajes y correas filtran parte de ese detalle; las bases « Direct Drive » lo transmiten todo sin ninguna latencia.
¿Los pedales tienen retroalimentación de fuerza?
Passive pedals don't — but brake feel is just as decisive. Load-cell and pneumatic pedals deliver pressure-based braking with zero fade, and add-ons like the SRP Haptic Kit bring ABS and traction-control feedback straight to your feet.
¿Es importante el « FFB » para el tiempo por vuelta?
Sí. FFB te indica que los neumáticos están al límite antes de que te des cuenta. Los conductores que aprenden a interpretar el ángulo de deslizamiento y la transferencia de peso a través de las ruedas frenan más tarde y evitan los derrapes antes.
¿Cuál es la diferencia entre la transmisión por correa y la transmisión « Direct Drive »FFB?
Los sistemas de correa suavizan (y pierden) los detalles más sutiles al pasar por la correa y las poleas; Direct Drive monta el motor directamente sobre el eje para ofrecer una respuesta sin latencia y con todo el detalle. Consulta nuestra guía sobre el accionamiento directo (Direct Drive , DD) en para obtener un análisis completo.
¿Una mayor potencia de « FFB » implica una mejor respuesta?
No — clipping kills detail. When the signal exceeds what the motor can output, the peaks are cut off and the information is lost. A properly calibrated mid-strength signal beats a maxed-out one. Try the Signal Lab above to see it live.
