I find the rears last longer... but +100,000 miles it's good practice to do all suspension related components if you want to experience the way the vehicle is supposed to feel. BMWs are hard on suspensions... is what it is, and why they drive the way they do. You can upgrade to poly bushings or other aftermarket solutions if you want more longevity and are willing to give up a small amount of compliance.
