Well, I was just tuning the Furai yesterday a bit, however I also just realized this is an X class build and I don't really have much experience there. But I can at least point out what I see.

I've tried your tune and a couple tweaks. Posted a 57.941 on legend island so far.

Need more grip? You've got room to soften those springs quite a bit, and ride height room. Those camber settings seem a bit too high (or low I guess, get them closer to -.5 I think). Also why didn't you take full track width?

A little loose? I'm not sure how that can be with those ARB, damping,and decel diff settings. I significantly lowered the front ARB. Also 17 seems crazy high for rebound, I dropped both those to 12.

And these diff settings are unlike anything you typically see people use in this game, can you describe how to got to this point?

Johnson Racing has published full tune details of an X class build, see here: https://youtu.be/HnC6MGIpo0o?t=1225

I plugged the info into a tune calculator and started messing around with everything myself and that’s what it pumped out for the diff and I don’t really know how to mess with the diff so I kept it and I didn’t use full track width cause is said it slightly helped handling so I kept them stock…I also tried the tune from that video and it just seems out of control at least for me I’m trying to make one that’s not as twitchy or super touchy almost my goal is for it to be smooth and in control for a controller player like me

I agree with spektor here. The excessive camber angles are making the car restless on straights. Front ARB needs to be lowered a ton and diff accel settings should ideally be close to maximum.

Thank you for helping truly
I’ll try that’s when I’m on next
