These are the questions I get asked most about car setups in Assetto Corsa Competizione. If you're new to setup work, start with my ACC setup guide.
How do I load a setup in ACC?
On PC a setup is a single JSON file:
- Copy the setup's JSON file.
- Paste it into the ACC setups folder for that exact car and track:
Documents > Assetto Corsa Competizione > Setups > [car] > [track]. - Start a session, open the setup screen and pick it under "Load Setups".
Can I use setups on PS4, PS5 and Xbox?
Yes. The only difference is that on console you can't copy a file across, so you enter each value by hand on the setup screen once the session has started.
To read the values, load the JSON into the ACC setup viewer and copy them over one by one. Make sure you're on the same car and track as the setup, otherwise it won't work.
Can I use a setup on a different car or track?
A different car: no. ACC won't load it properly, so the file always has to sit in the folder of the exact car it was built for. That includes EVO and non-EVO versions. The Audi R8 LMS EVO and the Audi R8 LMS EVO II can't share a setup.
A different track: yes. Since version 1.9 you can run the same setup at another track without any issue. It just won't be optimised for it.
How much faster will a good setup make me?
It depends on what you're comparing it to. Coming from a default ACC setup, finding 4 to 6 tenths a lap is realistic, sometimes more.
Why is a slightly oversteery car faster than a stable one?
A car with a touch of oversteer rotates sooner at the apex, so you wait less and pick up the throttle earlier. That's a small gain at the mid-corner and exit of every corner, mostly the slow ones.
You can't overdo it. Too much oversteer and you start losing braking stability and traction. But a little is always worth having, even though the car feels harder to drive.
So the real question is whether you want a stable car that's easy to drive or a harder car that's fast. I know it's frustrating to lose the rear and spin. After a while you get used to the aggressive front end and the lap time comes.
