Which ones did you go for out of interest? Any pics I've been looking out for some 16s for the winter months. I may leave them on year round too just to get a bit more comfort - not that it's terrible as is compared to rock hard leon FR (mk2) I had before it. I quite like the exeo ecomotive 16s but not sure they'd fit the 170 with the bigger brakes. That and I never see a set for sale!
