I had my 2000 S at the shop yesterday for a track inspection.  (Yes, there are still some events left this year.)  While it was up on the rack, I took a look around the front and saw that it seems to have a couple of plastic pieces torn off.  Can anyone tell me what they are for and whether or not it’s worth replacing them?  Looking at the Katalogue, I think one of the missing pieces is a rubber lip # 996 504 603 00.
Thanks,
