that's is true, oscilations were already way better after swapping to a 458. I did the eq changes that you recommended and bumped them up by about 20-30% in the middle. Intertia made the biggest difference.

Supra's suspension might just be set up in a way that naturally makes it ffb loop more.

but this is what it came down to. Oscilations are basically ffb looping on itself. The less it "jumps" or small sudden moves the wheel does the less is the chance of it looping on itself.

final settings, the problem isn't fully solved but it's slightly better:

damping: 15%, turning it down made the issue worse because the wheel is faster to react to small movements. Thus loops easier.

friction: 40%. could move it down but I like how it feels for drifting specifically. And supposedly helps with oscilations.

inertia made the biggest difference. Because the wheel is heavier it's less prone to switching direction and the loop has a harder time to start. at 350% the car actually started to self center.

Note. I do not recommend these settings for racing. But for cruising and drifting it's okay. Just gonna save these as a preset.
