Our x5 came w standard wheels (209 or 210s, 255/55/18s) - I'm looking to get 20s with 275/40 & 315/35s - Its an Xdrive
As I understand with current suspension it would get really bumpy and uncomfortable - Is there a Koni or H&R shocks/ Dampeners you guys suggest to go with to make the ride smooth as is on the M-Sport with this wide wheels ?

thanks for the help!
