Item is on Ebay, everyone here knows what these are so am not gonna bother w/ descriptions. Part number and all specs found on ebay - use the link.
I'm going to start ordering some bushings for my 2003 M3 before too long. The car has 118,000 kms on it so they're probably due for a change. I notice a clunk from the rear of the car when I shift at low rpm around town so I know the sub frame bushings and rear differential bushings...
