SimFoundry exists to simplify the chaos of modding. I curate the best cars and tracks so you can spend less time searching and more time driving.
My name is Steve Worrell. I’ve been sim racing for over 30 years, and I play just about every sim out there. I also run an LMU community called ADRR, which is another passion project of mine. Over the years, I’ve always loved discovering mods for Assetto Corsa and other sims.
While there are existing resources for finding mods, I’ve often found them frustrating to use. It can be difficult to filter out low-quality content and hard to discover mods that actually match your preferences.
I want to spend my free time on track. Not browsing page number 47 of a forum.
Over the 2025 Christmas break, that frustration hit a new level when I found myself sitting through unskippable video ads on a popular mod site, only to download a mod that wasn’t remotely what I was hoping for.
SimFoundry is designed to curate mods from across the internet and present them in a clean, user-friendly interface that makes discovery simple, fast, and enjoyable.
You (hopefully) won’t find low-effort, abandoned, or very early-stage work-in-progress mods here. I say “hopefully” because every mod you see has been manually tagged by me. Some I’ve personally used, some I’ve tested, and others I’ve assessed based on experience and context.
That does mean there may occasionally be mistakes, the odd incorrect tag, or a slightly clumsy AI-written short description. But this will improve over time as I refine and clean things up.
If you’d like to help support SimFoundry, there are two ways you can do that:
1. Join the Discord.
I’m actively looking for curators, people who want to help qualify, review, and surface great mods for the community.
2. Become a Patreon supporter.
I’m not trying to make money from this project, but it does cost a fair amount to run. If you like what you see and want to help cover the monthly costs, your support would mean a lot.
