Origins of the "Hump" on '03 Coupes And New Seatbelt
Alright, so I went to my service rep today becuase a part on my door broke and I asked about the hump. Here is the story:
02 owners complained that when they 'crack' open the roof there is a very annoying whistle. This hump will stop that noise. It will be on all new 03's that were produced after a certain date. Those who have earlier 03's will not have them. They can be added afterwards, but I don't have a part #. If the whistle bothers you, go add the part, otherwise, leave well enough alone.
In case anyone is interested my 03 also has a new feature...the seatbelts have a guide/holder to keep the belt in place and help to reach it. This cannot be added or removed, sorry 02's.
Thanks,
Erik

Any chance they were talking about the loud wind buffeting - subsonic rather than whistle sound - that happens at speeds above 30? That bugs the crap out of me!
If it fixes that I'm all over it - can you clarify that for us?
Also - what belt holder? I have an 03 and my belt is a pain to reach for.

Im glad you brought this up. When i went to the dealer i saw over 10 coupes and one of them had a little hump on the top roof, looked like a Xm Antena but much smaller.
Basically since i have a 2003 i didnt get one, and should this be added. Because at 30-40mph with just the sunroof open there is this anyoying wind noise.
Try to find out if thats what its for

Alright, lets clear this up. There are something like 10 new features on '03's that are not in '02's. I don't know any besides the belt and the roof, but the tech said offhand he knows there are more. Here is a pic of the belt. It moves in a 180 degree rotation and the end rotates another 180 degrees. Hard to explain. Please see pics. It is built in and cannot be added (or so I am told).
The last pic is the "hump" in case anyone doesn't know what it looks like.

The pictures of that belt clip thing still make no sense to me. I can't tell how it helps you reach the belt. How about a non-close-up pic (at a smaller resolution plese
)

Yuck. What an ugly and inelegant solution to the wind noise problem.
Couldn't they design something that pops up only when the roof is up? Its almost unbelievable that they would just bolt an ugly lump of plastic to the roof to try to solve the problem.

What are you guys talking about? The entire front part of the roof pops up when the glass is slid back. This acts as a deflector. Try pulling it down while driving and you'll notice a BIG difference in sound.
I hazzard to guess that this stick on hump is to reduce whistleing when the roof is TILTED. Not slid back as many of you think.

It looks a lot bigger then it really is. IF the dealer did not point it out to me I might not have noticed it.

Order it...
Install it.
OR Sell your '02 and buy an '03 (But I think the first might be easier and cheaper.)

Actually, I like the little pull tab. Wonder if you can put a Type-R sticker on it?
