A racing simulator is a loop. You steer, brake and accelerate; physics software continuously calculates how the car responds; and the rig sends that back to you through the steering wheel's force feedback, the screens or VR headset, and, on a full-motion rig, a platform that moves your seat. The better each part of that loop, the more the car feels like a car.
1. The Software: Physics and Tracks
Everything starts with the simulation. A sim like Assetto Corsa models tire behavior including flat spots and heat cycles (graining and blistering), aerodynamics, and hybrid energy recovery, and its circuits were built with laser-scan technology. iRacing describes the same approach on its track technology page: laser-scanning reproduces the cracks, camber and undulations of the real surface, and its sim adds dynamic track conditions and weather. The software also outputs telemetry, the data stream that drives the wheel and the motion platform.
2. The Wheel: Force Feedback
The steering wheel is both an input and an output. A motor inside the wheelbase pushes back on your hands to tell you what the front tires are doing: weight building in a corner, grip fading, a curb under the wheel. A direct-drive wheelbase connects the wheel straight to the motor without reduction gears or belts, which avoids the play and smoothing that gearing adds. High-end units are strong: Simucube rates its Simucube 2 Pro at 25 Nm of torque.
3. The Pedals: Measuring Force
Better rigs use a load cell on the brake, which measures pressure rather than pedal travel, the way a real race-car brake is controlled. Heusinkveld's Sprint pedals, for example, use a 120 kg load cell on the brake with up to 65 kg of actual braking force. Read more in our explainer on load-cell pedals.
4. The Display: Triple Screens or VR
Three screens wrapped around the driver give peripheral vision for judging corners and cars alongside. VR puts the driver inside the cockpit with natural head movement. Most serious sims support both; Assetto Corsa lists compatibility with Oculus and OpenVR headsets and triple-monitor setups.
5. The Motion Platform
A motion platform moves the seat to give your body cues the screen cannot. SimsForHire's full-motion rigs use SIGMA Integrale 2DOF/3DOF motion platforms, which are electric. Sigma's DK2 actuator is a servo motor driving a ball screw, with 2 inches (50 mm) of travel. Sigma's motion software builds the movement in layers:
- Pitch from braking and acceleration, so you tip forward under braking.
- Roll from steering, so you lean into a corner.
- Heave for bumps and suspension settling.
- Road vibrations per corner of the car, so a curb on the left is felt on the left.
- An environment layer that follows the car's real pitch and roll, such as a banked turn.
Because a platform can travel just a couple of inches, it cannot reproduce a long, steady acceleration directly. Simulators use tilt coordination instead: they tilt the seat slowly so part of gravity stands in for the acceleration. A DLR thesis on motion cueing explains the technique and notes that it is especially helpful in long curves.
Electric vs Hydraulic Motion
Some arcade driving cabinets use hydraulic motion. Electric actuators like Sigma's use motors and ball screws, so there is no hydraulic fluid or pump. Our rigs are electric.
How This Compares With a Professional Team Simulator
Formula 1 teams use the same principles at a far larger scale. Mercedes-AMG PETRONAS F1 Team explains that its driver-in-loop simulator uses lidar-scanned track models and a cockpit with the same chassis, steering wheel and pedals as the car, and that a lot of time goes into correlating the virtual car with the real one. An event rig is not a team factory simulator, but it uses the same building blocks: physics software, force feedback, force-sensing pedals and motion.
Why This Matters for Events
For guests, the parts add up to a car that responds the way they expect, which is what keeps people lining up for another run at corporate events, private parties and brand activations. You do not need to understand the engineering; SimsForHire delivers, sets up, staffs and tears down the rigs at your venue or hotel. See the cars and tracks pages for content.
