Sim Racing Pedals

Potentiometer — measures position

A potentiometer pedal measures how far down you press. It is the same principle as a volume knob. Movement becomes an electrical signal.

The problem is that braking force is not about how far you press, but how hard. A cold brake disc needs more force than a warm one. You vary your input every lap without noticing, and the simulator reads position as if it was consistent.

Potentiometer pedals are in almost all entry level equipment. They work to get started, but they set a ceiling on consistency.

Load cell — measures force

A load cell pedal measures how hard you press, not how far. The sensor registers real force in Newtons or kilograms. That is also how a real brake pedal feels under your foot.

That makes braking reproducible. The same force gives the same input every time, regardless of temperature, fatigue, or seating position. That is exactly why a load cell is the baseline for trail braking and other precision techniques.

The Simagic P1000 in Stage 1 is a three pedal set with a load cell on the brake. It is the entry point. Not a compromise.

Active pedals — load cell plus servo feedback

Active pedals build on load cell technology, but add a servo motor that adjusts resistance in real time. The pedal responds back to you, based on what is happening in the simulation.

That can be ABS pulsing felt as a staccato resistance underfoot. Brake temperature changing the pedal character through a long race stint. The difference between a GT3 car and a formula car. All of it happens automatically, without you changing settings for every car.

The Moza mBooster in Stage 2 works this way. Dual 200 kg load cell sensors combine with a servo motor and ball screw to create a dynamic resistance a static pedal cannot replicate. It is not just harder or softer. It is a different way to drive.

Hydraulic and pneumatic pedals

Hydraulic and pneumatic pedals also exist. Both can deliver a more organic pedal character, because resistance is built with fluid or air pressure rather than electronics.

Hydraulic pedals have long had a reputation for the most realistic brake feel. A progressive resistance similar to a real race car brake pedal. They do require maintenance, and they are more sensitive to temperature changes.

Pneumatic pedals are less common in the consumer market but are used in professional simulators. They provide an air spring resistance that can be tuned via air pressure.

RaceLoop currently does not offer hydraulic or pneumatic pedals in our packages. We go from load cell straight to active tech in Stage 2, because active pedals offer more control and adjustable characteristics without the maintenance burden.

Quick comparison

What the pedal actually does for your driving

The question is not which pedal is most expensive. The question is which one lets you build the right muscle memory.

Trail braking, progressive throttle out of a corner, brake point consistency over a long race. All of it depends on the pedal giving the same input every time you do the same thing with your foot. A potentiometer pedal cannot guarantee that. A load cell can. An active pedal can, and it also gives you feedback back.
