18" vs 19" wheels - ride quality

[dhu1]

Thanks to everyone's opinions...looking at either keeping our 15' S or selling and getting the 3, the suspension was the only issue my wife had an issue with...I drove 19" rims and was harsher than my coil S, did a vibration test and you can see the difference. Will try to do the same with a 3 with aero rims.

There is another thread that goes through all of this....

18" or 19" wheels

i have both a M3 with 18" aeros and 19" stock rims. I added some commentary in my post about the comparison between the two. M3 with 18" is definitely a softer ride (perfect for my wife for local roads). I had to soften my 19" by adding Unplugged springs--which I really like.
