Hi, new to the forum, and Z4 ownership. My 03 2.5i has 16" alloys at the moment,and I need to change them at least in the spring. I really like the look of the 18" elipsoids, but want to ask what difference to ride the bigger alloy might make to the Zed. The ride right now is very smooth and positive, but would bigger rims mean too harder ride? Be grateful for your experiences. Cheers
