More wheel, tire and suspension options in the garage of Forza Horizon 2 on PC (Azimuth), for every car, imported ones included. They're real upgrades: they show up in Upgrades > Tires & Rims beside the game's own, preview live on the car, are bought and installed like any other part, and are saved with the car.
This package contains no game files. The installer builds its database changes on your own game's files and installs them with backups.
| Front / Rear Wheel Offset | Stock, -20 to +50 mm a side in 5 mm steps, then +75, +100 and +150 mm (way past the fender) |
| Front / Rear Tire Profile | aspect ratio -30 to +35 points on the same rim: a 255/40 with +10 becomes a 255/50 |
| Rear Rim Style | a different rim on the rear axle (needs an aftermarket front rim); Stock puts the front rims back on |
| Rim sizes | 13" to 24", front and rear, besides the car's own sizes (smaller ones lighter, larger ones heavier) |
| Tire widths | 185 to 395 mm in 10 mm steps, front and rear, besides the car's own widths |
| Tire compound | drag and rally tires for every car |
Under Tuning, on cars with adjustable springs: ride height 10 cm lower and 40 cm higher than the game allows, camber -15 to +15 degrees.
The offset and profile categories use the wheel camera, so the car stays in view while you pick.
What you need
| | |
|---|---|
| Forza Horizon 2 | version 1.0.0.64 (Anthem_1.0.0.64_x64__8wekyb3d8bbwe), running on Azimuth 0.9.10 |
| FH2 Extra Options | the build for Azimuth 0.9.10: winmm.dll (with FH2_ExtraOptions.ini) beside azimuth.exe. It's what makes the game load the changed database (from Mount\mediapc); the installer turns on its [Files] EnableMediaOverrides=1 setting if it's off. |
| Windows | 10 or 11, with the built-in Windows PowerShell 5.1 (nothing to install). sqlite3.exe is downloaded from sqlite.org on first use (hash-checked) unless it's on your PATH. |
Install
1. Close the game.
2. Extract this zip anywhere and keep the folders together.
3. Double-click `Install-Fh2wheels.cmd`. It asks for two folders, one after the other:
- your Azimuth folder (the one with azimuth.exe);
- your game folder (the one with the Mount folder in it, e.g. Anthem_1.0.0.64_x64__8wekyb3d8bbwe). It shows the game folder that Azimuth is set to run; press Enter to use it.
A wrong folder is asked for again. If the game folder isn't the one Azimuth runs, you get a warning first: install into the folder Azimuth runs, or the game won't see the mod. It shows both folders and asks before changing anything.
If another mod has put files in `Mount\mediaoverride` (some mod packs, such as backports of newer Forza titles, install there instead of Mount\mediapc), the installer asks whether to install into Mount\mediaoverride as well. The game reads that folder first, so when that mod has its own game database there, fh2wheels has to go there too. It's then built on top of that mod's database, keeping its changes, and that mod's files come back when you uninstall fh2wheels.
If you have more than one Azimuth folder, install fh2wheels into the one you start the game from: each Azimuth folder has its own copy of fh2wheels.dll.
4. Start the game; the new options are in Upgrades > Tires & Rims.
Imported cars (e.g. with the FM5 car importer): the rim sizes, tire widths and drag/rally tires are made from each car's own options when you install. For cars you import later, run Install-Fh2wheels.cmd again afterwards. Wheel offsets, tire profiles and rear rims work on every car either way.
Updating: extract the new version and run its Install-Fh2wheels.cmd. It replaces the old one.
Uninstall
Close the game and double-click `Uninstall-Fh2wheels.cmd`. It restores the game database from the backup and takes fh2wheels.dll out of Azimuth.
The installer's backups are kept in <game folder>\mod-backups\fh2wheels-<date>. Mods that went in after fh2wheels (for example cars imported afterwards) have to come out first, newest first, before the database backup can be restored; the uninstaller says so when that's the case.
Cars that had fh2wheels parts fitted keep the saved part, which does nothing without the mod. Refit stock in the garage before uninstalling if you plan to share a save.
Troubleshooting
Two logs tell what happened:
•`fh2wheels-install.log`, next to Install-Fh2wheels.cmd, written on every install or uninstall (in %TEMP% when that folder can't be written). It has everything the installer showed, any error, and a report of your setup before and after: the folders, Azimuth and Extra Options, the DLLs in data\bin, whether the game folder has fh2wheels' database part, and the start of fh2wheels.log.
•`fh2wheels.log` in Azimuth's data\bin, rewritten each time the game starts with fh2wheels loaded. If it isn't there or isn't from your last start, the game didn't load fh2wheels.
When reporting a problem, send both, and say which folder you start the game from.
| What you see | Usually |
|---|---|
| "The installer's files aren't all here" | The .cmd was run from inside the zip. Extract the whole zip (right-click > Extract All) and run it from the extracted folder. |
| No new options in Tires & Rims, not even the new rim sizes or tire widths | The game isn't reading the database fh2wheels installed. Most often another mod has its own game database in Mount\mediaoverride, which the game reads first: install again and answer Y to installing into Mount\mediaoverride. Otherwise the game was started from a different Azimuth folder, or runs a different game folder than the one installed to. The install log's report shows which database the game reads and whether it has fh2wheels; fh2wheels.log says so too (PROBLEM: line). |
| Upgrading or uninstalling the other mod in Mount\mediaoverride | Uninstall fh2wheels first, then update that mod, then install fh2wheels again. Otherwise one would undo the other's database changes. |
| Options there, but blank text, or the rear rim changes all four wheels | The database part is installed but fh2wheels.dll isn't running: no fresh fh2wheels.log. Usually the game was started from another Azimuth folder with an older copy (each Azimuth folder has its own). |
| Everything stopped working after updating or reinstalling Azimuth | Azimuth put its own azimuth-tls.dll back, which takes fh2wheels out. Run Install-Fh2wheels.cmd again (1.1.1 or later). |
| "Close Azimuth first" | The game is still running; close it (check Task Manager for azimuth.exe). |
| "Needs FH2 Extra Options" | Install Extra Options for Azimuth 0.9.10 (winmm.dll beside azimuth.exe) first. |
How it works
•`fh2wheels.dll` goes into Azimuth's data\bin as azimuth-tls.dll; the DLL that was there is renamed fh2wheels-next.dll, and fh2wheels loads it, so Extra Options and Azimuth keep working. It applies the offsets and profiles when a car is built, shows the rear rims, lets the game sell the new parts, and supplies the menus' text. Settings: data\bin\fh2wheels.ini; log: data\bin\fh2wheels.log.
•The game database (Mount\mediapc\stripped\gamedbRC.slt): the new categories and options, each car's rim sizes, tire widths and drag/rally tires, and the ride height ranges. The camber range is in Mount\mediapc\physics\PhysicsSettings.ini.
Both halves are needed: without the DLL, the offset and profile options do nothing and their text is blank.
The rear rim is kept in the car's save (in the garage's unused tire brand field). The game has no slot for offsets or profiles, so they borrow four part slots ordinary cars don't use (restrictor plate, motor parts, quad turbo and electric motor); the DLL keeps the game from treating them as engine parts.
With fh2net
fh2wheels and fh2net both sit in the azimuth-tls.dll chain and work together, installed in either order: fh2net always ends up in front (fh2wheels goes behind it when it's already there), and each can be updated or uninstalled on its own.
Known limits
•A rear rim shows only with an aftermarket front rim: with the stock rims, the car draws its own wheels on all four corners.
•The game doesn't draw rims larger than 24", so the sizes stop there. Cars that come with larger rims keep them.
•Very wide tires and big offsets go through the bodywork; that's the point for some builds.
