Help with Translating Assetto Corsa Car Data (file .ini) for ChassisSim Modeling

[Domenico17]

Hi everyone,

I'm working on creating a custom model in ChassisSim for a Mazda MX-5, starting from a base model (specifically, a Lotus Elise) and adjusting parameters to match the MX-5 as closely as possible. My goal is to create a reliable baseline setup for different races, so I can quickly make adjustments on race day.

I've been pulling data directly from Assetto Corsa, and I found the .ini files with car data. While I can read these files, I’m having trouble understanding how to interpret the data and input it correctly into ChassisSim. Specifically, I need help with:

• Suspension data from suspensions.ini (wheel rate, camber, toe, etc.): How do I accurately transfer these values into ChassisSim?
• Differential settings from differential.ini (power and coast ramp): Any tips on aligning these values with ChassisSim's settings?
• Aerodynamic and weight data from aero.ini and car.ini (downforce, drag, centre of gravity and inertia): How should I handle these parameters for accurate vehicle behaviour?

I’d also appreciate any advice on converting units, as I noticed that Assetto Corsa and ChassisSim may use different unit systems.

If anyone has experience with building models from Assetto Corsa data, I’d love to hear any best practices, tips, or resources you can recommend. Thanks in advance for any help!
