Driving feel in Forza Horizon 6
In Forza Horizon 6, 2018 Subaru WRX STI ARX Supercar sits inside S1 Class (supercar tier). expect a supercar bracket where corner-entry confidence and aero feel start to dominate. S1 cars suit players who already trust their racing line and want a faster, less forgiving car for road and street race events.
Where it shines
S1 class fits faster road events, longer point-to-points and online cruise lobbies focused on supercar showcases.

Tunes here often balance launch grip vs top-end. If you mostly run open road events, prefer a tune with steadier mid-throttle response over absolute V-max.
These are general starting points only, not a guaranteed competitive setup. Forza Horizon 6 community tunes that already have hundreds of downloads are usually a faster route than building from scratch, especially if you are not sure of the car's drivetrain or aero behaviour yet.
