2003 BMW Z-8. A NUMBER OF OWNERS HAVE REPORTED DAMAGE TO THE ALUMINUM FRAME AT THE SHOCK TOWERS. AS THIS AFFECTS THE SUSPENSION AND STEERING THERE IS THE POTENTIAL FOR ACCIDENTS RESULTING FROM THIS DAMAGE. BMW HAS BEEN AWARE OF THIS PROBLEM FOR A WHILE AND IS NOT RESPONDING WITH A FIX NOR IS IT NOTIFYING OWNERS OF THIS CONDITION. I BELIEVE BMW HAS A SIMILAR PROBLEM WITH OTHER MODELS. NOTE THAT THE Z8 MODEL IS NOT LISTED IN YOUR DATABASE SO I CHOSE Z4 FROM THE PULL DOWN LIST. *NM
