recently brought a new 06sl and now the wifey is looking at 20inch rims. the question is how much of a ride change is the 20in compared to stock. the sl comes with 17 and they say that you can go up 2 inchs with no problems. so i know that the se has 18 and theyre the same car except for shocks and springs i believe. would a 20inch give the hard rent a car feel. i know they look nice but she doesnt want to lose to much ride quality. for the price the 18 and 20 are about the same. just dont know what to do. if anyone has 20 and can say how the ride is it will be much appreciated. oh and do you get any excess interior noise from the 20. i know has tires get smaller the ride gets worst. any help will be much appreciated
