I got 30mm H&R ones for the back of my XF.
When you get them you will realise you have quality, and it's money well spent.
I was a bit reluctant, wondering why I got that size, but what a nice fit!
I got the wheels balanced at the same time whether they needed it or not. No issues with geometry.
It was recommended to get 20mm for the front as I've got 18" wheels.
which I think I'll do.
