Well it was either just being lazy and not caring enough or the constant reminders from: EDDYFIG and josec70 but I swapped out the F90's for the M550i's.

The drop is clearly stronger/lower in the rear and even the front is slightly lower. I got a chance to drive it thru some pretty curvy roads on the way home for about 40 miles and the car dynamics in regards to compression and rebound are pretty much equal to the F90. Im glad I did it and yes it took a while but when I did the F90 springs over a year ago- the M550i springs were not being done by enough owners for me to take a chance. I still am a bit angry at H&R for showing a drop of 1.2/1.2 on their site for the F90 set up. Why not just say it like it is: 1.2/0.6 .... anyways I digress cause Im happy.

Big shout out to Ben at RG Sport who sourced the springs in 24 hours and did the install in about 3. Very fast, professional, and extremely price aggressive. r33_RGSport Thanks again Ben and Ill be over there soon for more mods.
