Sim racing is racing in a simulator: a wheel, pedals and a screen, connected to software that models the physics of a real car. It is not just a game anymore. Real drivers use the same simulators to learn tracks and practise their braking, and more and more people train with one at home.
This guide explains how it works, what you need to get started, and how to set up your practice so you actually get faster instead of just doing laps.
1. How does sim racing work?
A racing simulator calculates, many times a second, what your tyres, suspension and engine are doing. Your wheel passes that back through force feedback: the wheel goes light when the front tyres start to slide, and heavy in a fast corner. Your pedals measure how hard you brake and how much throttle you use.
Because the software measures everything, you can see exactly what you did after every lap: where you braked, how much speed you carried through the corner, when you got back on the throttle. That data is called telemetry, and it is the big advantage of training in a simulator.
Well-known simulators are iRacing, Assetto Corsa Competizione, Assetto Corsa EVO, Le Mans Ultimate, rFactor 2 and Automobilista 2 on PC, and Gran Turismo 7 on PlayStation.
2. Why simulator training works
- Repetition for free: practising the same corner a hundred times costs no tyres, fuel or track rental.
- Measure instead of guess: telemetry shows where you lose time. No guesswork.
- Find the limit safely: in a simulator you can discover where grip runs out, and going off costs nothing.
- Learn tracks: got a track day coming up? You will know the braking zones before you arrive.
3. What do you need to start at home?
- A PC or console: a regular gaming PC or a PlayStation is enough to begin. To get more out of your PC, read optimize your PC and rig.
- A wheel and pedals: an entry-level belt or gear-driven wheel is plenty to learn on. A controller works, but you miss the feel of force feedback and brake pressure.
- A solid spot: a desk that does not move and a chair that does not roll. A proper cockpit only pays off with a direct drive wheel or load cell pedals; read choosing a sim racing cockpit when you get there.
- A simulator: pick one and stick with it at first. Every sim feels different, and switching slows down your learning.
Not sure which hardware suits you? The free Rig Tuner looks at what you already have and tells you honestly whether an upgrade makes sense.
4. A four-step training plan
Step 1: learn one car on one track. Choose a forgiving car, such as a GT3 or a Mazda MX-5, and a track you enjoy. Drive until your lap times are within half a second of each other. Consistency comes before speed.
Step 2: measure your laps. Record a good lap and look at the telemetry: where do you brake, how hard, and when do you get back on the throttle? What is sim racing telemetry explains how to read those graphs.
Step 3: work on one thing at a time. Most of the time is usually in braking: too early, too soft or too long. Pick one corner, change one thing, and measure again.
Step 4: only then adjust your setup. A setup only makes you faster once you drive consistently. If the front washes out or the rear steps out, read fixing understeer and oversteer.
5. Learn faster with AI
Reading telemetry is a skill of its own. That is where the Pitcrew Academy tools help:
- PitCrew Overlay: free app that reads your sim live. After every lap you see per corner where you lost time, and with an AI session (5 credits, 2.5 hours) an AI race engineer tells you what to do differently on the next lap. No export or upload needed.
- AI Setup Engineer: describe your problem, for example "understeer on turn-in at Spa", and get a concrete setup change with an explanation.
- Video analysis: upload an onboard video of your lap and the AI points out where you lose time and what to do differently. Live after every lap, the free PitCrew Overlay does the same.
- Rig Tuner: advice on your wheel, pedals and PC, for your sim.
You can try every tool for free, no credit card needed.
Frequently asked questions
How does sim racing work?
You drive with a wheel and pedals in software that models the physics of a real car. Force feedback tells you through the wheel what the tyres are doing, and the software measures everything you do, so after each lap you can see where you lose time.
Can you really learn to race in a simulator?
Yes. Braking, the racing line and track knowledge carry over well to the real track. What a simulator lacks is g-forces, so your feel for the car keeps developing on track.
What does a home sim racing setup cost?
If you already have a PC or PlayStation, you start with an entry-level wheel with pedals and a simulator. A cockpit and a direct drive wheel are a later upgrade, not a requirement.
How often should I practise?
Three focused half-hour sessions a week beat one long evening of laps. Work on one thing per session and measure whether it helps.
