My wife was in the X5 for the first time after I lowered it. I was not even out of my neighborhood when my wife looked at me and said "You ruined your car again, didn't you?" After a couple of seconds of stammering, I admitted to the new springs.
I really love the look of the lowered X5M. But I am thinking that I am going to have to put the old springs back on. I didn't go with a different exhaust because I put customers in my car. Not sure if the lowered springs are any better than the exhaust.
The handling has changed as well. The car/truck becomes very unsettled when you hit any king of bump mid-corner. I was taking an off ramp by my house at high speed. It is a fairly open ramp so you can keep the speed up. In the middle of the corner there is a bump. Never been a problem in the past. This time the car had a huge wiggle and became significantly unsettled.
Looks like I will go back to the old springs. Bummed that it did not work out.
