I put Goodyear F1 Asymmetrical 5's on my 330i a few weeks and to be honest I was not over impressed. Grip was great, but not very progressive, held on well but when it let go did it with some bite.
Also, found them a bit hard, which really surprised me, as had them in run flat guise on my F11 5 series and they were brilliant, didn't feel like a run flat at all.
So went with PS4s on the Z coupe a couple of weeks ago. So, so, so much better than the run flats on there and feel great, very progressive, great grip and excellent turn in. However, I wish I had gone up a profile on front and rear for a bit more bite on our crappy roads. 225.45.18 and 255.40.18 I think would be far better.
