Wing settings
The rear wing of a GT3 or GT-like car is one of the key values to set when building your setups.
The rear wing set to max produces the most rearward pressure on the car, helping with cornering and stability throughout your laps.
A higher rear wing setting also creates drag, which slows the car down on straight-line speed. In many simulations this becomes noticeable once you exceed the 200 km/h mark. On tracks with long straights like Monza, Le Mans, or Imola, you can lose lap time by running too much wing.
The force generated by the rear wing pushes the car down on the rear axle. It’s always a trade-off: drag for rearward pressure.
From my own testing, a single click of wing up or down rarely makes a dramatic impact on top speed. However, when I tune cars for corner-heavy tracks, I often prefer to run max wing so I don’t leave any cornering performance on the table.
Front splitter note
The front splitter is not a front wing.
- It’s mostly a ride height and platform tool, not a true aero device like the wing.
- A higher physical splitter on the car usually allows you to run lower overall ride heights without scraping, which can increase front load through the floor.
- A lower numerical splitter value in some sims means the part sits closer to the ground, which can add front downforce but also increases the risk of scraping.
How do you know which setting to use?
There’s no universal answer because every sim and car/track combo behaves differently. To find clarity, I create a balance with high, mid, and low wing settings in my builds.
I always start by tuning with the max wing and then check how my delta changes with lower wing values on the straights. Some cars simply don’t gain much top speed even if you drop the wing, which makes it pointless to sacrifice stability.
My process is simple:
- Set a lap close to my limit with the highest wing setting.
- Then test lower wing values and compare the lap time delta, especially in fast sections and on straights.
- After a few laps of testing, the right setting usually becomes clear.
