Mein Auto: BMW Z4 35is
Thanks for the link to the Car and Driver test of the effects of different wheel sizes on performance. Most of what I have read in this forum and elsewhere was opinion about what should be true in comparing 18 versus 19 inch wheels. Here we finally have data that counters much of the speculation, and it has convinced me to stay with the 18 inch wheels for the Z4 35is I have on order. I was tempted to switch to the 19 inch wheels just for the cool look, but loss in performance and harsher ride seem to be a big price to pay for an inch of cool.
