Not sure that I want to punch holes in that clean rear panel. I don't miss them to be honest.
I'll give it a think.
There's a lot of serious E9 pedigree weighing here here, so I'll give this serious consideration!
Can someone advise me: The bumper carries the main structural load, so the hole through the rear panel would be for access for the mounting bolt for the underrider, correct?
Merry Christmas, and all the Best for the New Year to All!
Correct! The lower hole is just to secure the under rider laterally. “Structural load” for the rear bumper is a misleading statement. The rear bumper provides no structural support for the vehicle, and for the most part provides zero protection for the vehicle short of a parallel parking graze. It is a beauty piece at best.
Got it. Yeah, as you say, this whole chassis "sways" in motion like a young Latin girl! ( I can say that because I was married to one many years ago... )
Rob was kind enough to point me to a pair of newly-chromed URs on eBay. They are coming from Latvia, so within the EU, so I can have them shipped to a friend's PO Box in Germany just saved me many $$$! Thanks Rob!
Gotta love this E9 community! Like the FAQ community, the best souls on the planet!
Hi Willem,
These underriders were an integral par of our Coupe's design with only one exception the 2.5CS were they were deleted to save money.
So unless you don't care about authenticity you really should have them installed. Just my 2ct.View attachment 57340
The big rubber block is only for US 1973 coupes with 2 1/2 mph interim bumpers. Earlier cars use #17, a small rubber strip. The chrome pieces should be the same, part numbers are the same whether for the chrome or the rubber bumper itself, weird that the pics make them look so different.
