I think everyone who has played Forza Horizon 5 has encountered the rather infamous Double-Wing 2005 BMW M3 which is due to the AIM9 GT Widebody Kit having an inbuilt Wing while still retaining the Ability to mount a second one.
This is the Bodykit in Question and as you can see only the Front Aero Tuning is Unlocked when adding it.
Currently the only way to Unlock the Rear Aero Tuning is to mount either the Forza Wing or the Big Country Labs Wing which leads to the Double-Wing Car.
It is pretty funny to have the two wings and it’s definitely a standout feature of the car which I wouldn’t want to get rid of for those who like it, however, personally I’m much more of a fan of creating a more realistic looking Time Attack/Hill Climb Style Car and currently you can’t do any Rear Aero Tuning while retaining the realistic appearance.
To Remedy this I propose enabling Aero Tuning on either/both of the two Ducktails Wings which are currently available from Rocket Bunny and SFLA or ideally just adding an AIM9 Wing which unlocks Aero Tuning but doesn’t change the Visual Model of the Car.
Personally I think the SFLA Wing looks the best and so would be my prime candidate if adding a Non-Visual AIM9 Option isn’t available but having it on both Rocket Bunny and SFLA would be ideal.
Thankfully not having the Rear Aero Tuning isn’t game breaking but I’d definitely like to see something to remedy it without needing to use a Double-Wing Setup.
