Am thinking about adding some noisekiller sound deadening. How do you remove the plastic trim pieces in the boot which fit over the wheel arches? I think this is where most of the road noise is coming from but I am just cautious of removing these pieces if the fittings which hold them in place are likely to break off. Any advice welcomed. Thanks.

Sorry for reviving an old topic, but I think I'll do the same operation myself.

So, there are a few things that you have to remove prior to removing that piece of boot trim you want.

 

Here's the guide I made for myself, and hopefully I won't screw up anything. https://drive.google.com/file/d/0B9bc5FrmuwbAYTA4Q3gzeUpISms/view
