Thanks for all of the input. The vent was put in by Steve @ Lemetry's Autobody in Maplewood, Minnesota. Ride is a little stiffer. Not as much as I thought it would be. The GY F1's have a sidewall rating of 89. The factory is 95. I had the wheels on, with and without the spacers and I do respect your opinion Johan. I like the "FAT" look that the wheels have. I have owned a few M3's and never have I looked at the back end of a car and said WOW that looks tough
as much as I do now. I love the rear end. NO pun intendid.
