Having the right iRacing setup can drastically improve your sim racing performance, but where do you start? Setting up your car in iRacing can seem overwhelming to begin with and finding improvements can sometimes feel like a random process. However, there are certain methods you can follow to make setting your car up a more systematic process that creates consistent and incremental improvements. In this iRacing setup guide, I’ll detail a few pointers to begin your journey to better understand sim setup and ultimately develop a faster car.

Using someone else’s iRacing setup won’t get you all the way

Granted, using an off the shelf option like the well-produced setups from VRS can be a quick win and you will likely find a chunk of lap time.  However, as with real-world racing, there is no one-size-fits-all setup. If you consider that track temperature, tyre condition and circuit evolution are constantly changing, it’s easy to see why. 

Track conditions in sim racing are simulated as in the real-world and are constantly changing.

That’s not to mention differences in individual driving style. We all have slightly different philosophies on driving style, how we prepare our car to corner, how we trail brake and how we load the car up into each bend, so it’s fair to say we all need a slightly different setup for our sim racing. If you really want to get into the details and build the best iRacing setup you can, you’ll need the ability to tweak setup yourself, to perfectly suit your own style, current circuit conditions and other variables such as whether your race is a sprint or endurance.  Using someone else’s setup can be helpful, but to be on the absolute pace you’ll need to go beyond this and understand how the car is behaving, where there’s potential lap time and which aspect of the setup to change next.

Be sure your driving technique is excellent

After training more than 100 drivers through our iRacing Fundamentals MasterClass and working with real-world drivers such as Tony Kanaan, we have found that most drivers need a bit of tweaking when it comes to their sim racing technique Usually, there are just a few small improvements needed which will create a significant lowering of lap time. Aside from lap time, our drivers report a deeper understanding of how their car is behaving, as they more mental capacity to feel what’s going on beneath them.  When changing your setup in iRacing, or any sim for that matter, you must first ensure you’re lapping consistently. By which I don’t just mean lap time, rather your inputs through the pedals and steering wheel.  We need to ensure the platform of your car is working properly and consistently through each corner. That way you can begin to assess potential issues with setup and have a clear direction of how to improve.

Give clear and honest feedback

If you’re not absolutely clear on how your car is behaving – for example, which axle is limiting you from going faster – you won’t be systematic in improving your car.  You must be able to drive your car and still have the mental bandwidth to feel, comprehend and commit to memory the balance of your car through each corner.  Beyond this, you’ll need to understand how your car is balanced when you turn in, at the apex and again when you pick up the throttle.  Each of these different inputs corresponds to a different iRacing setup change (or a number of changes) and so it’s critical that drivers understand their inputs and the phases of a corner. This is challenging, especially at the beginning as simply driving the car on the limit requires a lot of concentration. But with conscious practice, thinking of your driving in this way becomes second nature. You’ll quickly understand which end of the car is limiting and through which section of each corner.

Build your knowledge of mechanics

So, your driving technique is excellent and you understand how your car is limited in each phase of the corner. You’re ready to make a setup change! However, when you open the setup tab in iRacing, there are a hundred different things you could change. It’s tough to know where to begin. To start to get an idea, you need to have an understanding of how a car’s works dynamically. I know it sounds like a lot of learning, but this is interesting stuff anyway, plus it’ll make you a must faster sim racer. The first place to start is by watching our Driver’s University tutorials. Look out for the videos on the phases of a corner, weight transfer and trail braking. Chris Haye has put together a great introduction to how the sim racing setup works diving into topics such as springs, dampers, ride heights and anti-roll bars. You can find his YouTube series here Another great piece of content from Chris is this iRacing setup cheat sheet, which breaks down typical setup issues during cornering as well as other helpful tips.

Start with simple iRacing setup changes

In terms of setup changes, there are universal changes and specific changes. A universal change is something like raising the rear ride height (in a non-aero car), something like iRacing’s Mazda MX-5. If you raise the rear ride height, you’re essentially shifting more of the car’s weight to the front axle. That, in turn, means there’s more load – and so grip – going through the front tyres.  This will affect the car in every phase of the corner and all corner types (fast, medium and slow) and so we call it a universal setup change.  On the other hand, with a more specific change would be altering the slow bump on the front dampers. This would only affect the car during braking and corner entry.  Stiffen this up and the front of the car is better supported, leaving more weight in the rear of the car and so shifting the balance rearward (it’ll oversteer less on corner entry). In all of our real-world and sim racing courses, we find pupils learning significantly faster if things are broken down into their simplest form. So when you start making iRacing setup changes, you should take this into consideration and should start with universal changes. This way you have more opportunity to feel how the setup change affects the car, as it’ll be universally altered and the feeling will be more obvious. Once you’re clear on how a universal setup change feels, you can move on to more granular changes and get more specific with improvements.
