How to Simulate the Indy 500

The Indianapolis 500 is the greatest spectacle in racing. If watching it has you wanting to feel what that is actually like from the cockpit, we have got you covered.

This guide is for anyone who watched the race and wants to put themselves in the seat.

The simracing rig that makes your Indycar cockpit

A high downforce machine like the Indycar flies through corners at velocities that stagger believe. At these speeds the car communicates its limits through a gradual lightening of the steering wheel as the front tires approach the edge of grip.

• The danger of flex: If your wheel mount or pedal plate flexes even a millimeter, that vital force feedback detail is absorbed by your rig instead of your hands.

• The penalty: Missing that split-second sensation of the front end washing out means you won’t catch the slide until you're already in the wall. Especially at 220 miles per hour. 

SIMGASM Profile Rigs

To capture every nuance of the track surface, your chassis must be an immovable object. Aluminum T-slot profile rigs provide the modular, zero-flex foundation required for high-torque oval racing.

The Seat

During the Indy 500, the drivers experience a sustained 3.0-3.5G per corner. No matter how hard you train, it is impossible to fight to keep your body in place for two and a half hours. So, like the drivers, you need to have a seat that wraps around your shoulders and hips. The fibreglass fixed-back Atlas GT Seat gives you the support to be locked in for two and a half hours of racing. With the Seat bracket set you can tilt the seat back to be in a formula-style position, where your knees are at the same height as your shoulders.

Steering wheel and base

Wheel Bases: The Case for Direct Drive

Gear-driven or belt-driven wheel bases introduce mechanical friction that masks the subtle telemetry of an IndyCar. To hit consistent laptimes over the entire 500 miles, a Direct Drive (DD) base is highly recommended.

Options like the MOZA R9 or MOZA R12 connect the steering wheel directly to the motor shaft. When you run through Turn 1 flat-out, you will feel the steering column load up with heavy, realistic resistance.

Pedals: Mastering the Pit Entry Threshold

You rarely touch the brakes during a green-flag lap at Indy, but when you do, the stakes are massive. Transitioning from 220 to a 60 miles an hour pit lane speed requires absolute precision. Having to feather the throttle pedal as the wheel communicates a loss in front grip in the corner requires a throttle pedal that gives you the right resistance.

Standard potentiometer pedals measure the distance the pedal travels, which is incredibly difficult to replicate under pressure. A load-cell pedal system, like the MOZA CRP2, measures pressure—just like a real racing brake caliper. This allows you to rely on muscle memory to scrub massive amounts of speed instantly without locking the tires or picking up a catastrophic pit-lane speeding penalty.

Monitors: Replicating 180 degree awareness

At Indianapolis, it is not rare to go three-wide into turn 1. Spotters help, but nothing replaces actually being able to see where your competitors are alongside you.

A single monitor leaves you blind to your left and right rear quarters. A triple-monitor setup physically wraps the racetrack around your cockpit, allowing you to judge exactly how much room you have to clear a car on the inside or outside. Utilizing a heavy-duty, integrated triple stand ensures your monitors remain perfectly aligned and immune to the vibrations generated by high-torque wheel bases.

The software

When it comes to the software simulating the Indy 500, iRacing is the undisputed benchmark. It serves as the official simulation partner for INDYCAR, offering the most accurate recreation of high-speed oval racing available to consumer hardware. It has the whole 2.5 miles laserscanned, so every bump you feel through the wheel is there in real lifef too. iRacing has modeled the aerodynamics, track evolution and tyre wear, which gives you the most realistic feeling of what it is like to drive in front, alongside and behind other cars turbulent air. 

Hardware Configuration FAQ

Why do I need a high-torque wheel base if oval racing is just turning left?

Because it isn't just about turning; it's about holding resistance. At peak cornering speeds, the aerodynamic load places massive sustained torque on the steering rack. A weak wheel base will clip (max out its force output), clipping off the critical detailed vibrations that tell you if the rear tires are stepping out.

Can I run the Indy 500 effectively on a desk mount?

Yes you can. However, any direct drive wheel will be able to put enough force on the desk to make it flex. Any flex at your wheelbase attachment points creates an instance loss of force feedback detail. Furthermore, office chairs on wheels will push backward when you attempt to press a stiff, realistic brake pedal, ruining your braking consistency.

How much does FOV (Field of View) matter for oval racing?

Mathematically correct FOV is critical. At 220 miles per hour, your brain judges speed and distance based on how fast objects move across your peripheral vision. If your FOV is incorrect, your perception of the corner entry speed will be warped, leading to turned-in errors or missed apexes.
