A simple way to disable the chime on the drivers side can cost you just $1.00 yes just one dollar. And best of all you do it from the drivers seat as needed, such a simple way to address this issue and if you don't like it no big deal just go back to your old way.

They say a picture is worth a thousand words.
This one is from an older Audi 6000 from the junk yard and yes it fits our crossfires perfect. So grab a piece of paper trace out your seat bracket and go shopping at the yard and bring a knife to cut the web belt off.
More pics to follow on other little misc things/fixes to come so stay tuned.

P.S. This can be left in (connected) all the time to stop the chiming noise and removed as necessary to use the factory belt as per uncle sam.
