... remove the bolt covers on the bumper and remove the two bolts. The sides have slots that slide in to hold it. You'll have to unhook the fog light, side marker and temp sensor wires to it remove completely. Chris to remove the front bumper, do you just unbolt the two main bolts, or do you have to remove the small rivets underneath the metal bar that is between the bumper and the grill? thanks Eric 88M3
