They rub!
20mm All around installed this afternoon.
Stock Non FS 18x8.5. Same specs as F-SPORT.
Stock size 255/35/18 tires.
RSR Downs (approx 1" drop)

I don't know how it does for some, doesn't for most but they definately do (for me).
Only variable I can imagine is my springs have more miles on them, and settled slightly lower? I have no idea.

Look MUCH better though.though.
May follow up with pictures.

Both front and back rub, or just rear?

Just rear. And not all that hard to do either it was obvious within minutes of driving.

Not constant either but I will be replacing with 15mm for rear.

Thinking maybe tire brand has to do with why there is inconsistency with people rubbing.
I have Goodyear EagleSport all season.

I've read there are some variances in shape and sidewall structure across brands but I don't know if that would make the difference.

But in other news, looks much better.
Just disappointed with rub but hopefully will help others.

Thanks, just more affirmation for 20f/15r. As soon as the weather warms up I'll get mine on.

Not mentioned but relevant: do these use the existing or replacement full-length studs, or are they adapters with their own studs?
One is relatively safe, the other isn't.
Guess...

Installed the 15mm spacers in the rear today.
In comparison, my tires looked a little more squared off on the sidewalk than others. Maybe that's the difference.
a peek inside my rear fender wall...its been misplaced a bit.

What do you mean misplaced? And also do 15mm rear rub?

In that picture towards the rear you can see the fender liner has come removed from the clip.
In the other picture, you can see where there was some rub, nothing tragic.

15mm absolutely do no rub. I gave it my best shot on some less-than-smooth mountain roads yesterday.
And the same spots on the same roads that caused rub with 20mm I tested at higher speeds. Nada rub.

No I don’t. Still with in factory chamber angel in the rear. So no need for them. On the front my camber was like 1.8ish but that ok with me. Helps turn in.
