In September I went ahead and purchased some A8 rings which were going to replace the current ones on the car. I saw some people do it in the forums (Audizine) which I thought suited the trunk of the b7 very well. This of course gave me the perfect excuse to clean up the trunk a bit by removing the other badges. Here are a few pictures of the process; I dont have all the pictures of the steps because I got way to lost during the process.
Before
Used fishing line and a hair dryer to remove the badge then outlined it with tape to prevent myself from spreading the goof off everywhere.
With the badges removed and stock audi rings
Comparison of the old and the new rings :D
Old rings removed and I taped off where the old rings where to ensure correct placement of the new A8 rings
Another size comparison once the A4 rings were off
Finished product, must say I like it a lot better also gives the b7 trunk a beefier look which I'm going for.
