Your inquiry is a bit odd, as if you feel failure rates are absolute and based strictly upon miles or some folks with suspension issues are imagining things. Clearly, some cars have no suspension problems while other's do. The condition of each car's suspension varies WIDELY. Condition of suspension components is greatly influenced by:I have noticed multiple threads with front end issues as the main concern.

Monoball is for severe duty track junkies who are willing to give up NVH qualities for tiny gains in track perfomance............Case in point - I have thrust arm bushings that are torn. Do I put the OEM back in? Do I put the X5 bushing in, which although better, still seem to fail around 30k? Or do you go big dollar and put a poly or monoball in its place? ..........
I don't think upgrading to X5 bushings will cause any harm. Many members here have done that w/lots of miles now, with no problems. The Vines arms I have basically have upgraded bushings in them, but we'll see how long they last. The problem with a lot of this is that all of our cars are aging in the real world not on some test bed, so it's hard to predict what will happen to longevity until there is a failure or string of them some thousands of miles down the road. But by then, it's too late because either you will have done the same mods or not, and your car similarly will be thousands of miles older. The best we can do is identify a weak part and replace it with something that at least in theory should be more robust, and that because of the way it's hooked into other components, shouldn't cause follow on problems. The X5 bushing upgrade is one of those. It is far more robust in construction than the stock M5 bushing, the way it's implemented in the car shouldn't lead one to think it will cause failure of other components, and many members here report no problems with having them in over many thousands of miles. So this one is pretty low risk.My main concern is that by replacing the standard bushings with the more robust X5, I am going to cause a follow on failure.
I started another thread looking at this issue from the point of view that you have replaced the wear parts, then added and aftermarket suspension system. Did this increase/decrease/no change the wear parts B50 life?
