This is the install guide and impressions of an E93 carbon fiber trunk
Convertibles have a weight problem and since a carbon trunk is a popular weight reduction modification that can also look good I thought it made sense. The problem was the very limited selection of carbon trunks with E93 fitment. Previously you were limited to very expensive options including Duke Dynamics as well as Vorsteiner. This guide will cover the installation of a Vorsteiner rep trunk lid.
The trunk is not a 100% fitment, in fact, it requires a lot of massaging to make it all fit as there are little things you'll need to trim and grind on the interior FRP skin to make things sit perfectly like the lights and fitting the handle. These trims are just excess material left on the interior skins which weren't cut to a T. This isn't too big of an issue as they can be easily trimmed, I'd prefer they cut too little instead of too much because then you're left with a module that doesn't stay in the trunk or is loose. There are several companies that do sell a carbon trunk, this is the one that looked the best for the price I was willing to pay sight unseen.
For those who are willing to give this company a try, here is the listing: https://www.ebay.com/itm/322292253722
When I received it, the trunk came in a very nicely packaged box:
The carbon weave looked pretty good, I'm not an expert with this stuff but I was happy, particularly for the price I paid.
It wasn't perfect however, the corners looked like they had taken a little bit of damage:
Thanks to @Snelson3003 for the tip, buy a good set of Dremel bits: https://www.amazon.com/gp/product/B00T0PQ2TE/
The Dremel Flex Shaft helps get into tight areas: https://www.amazon.com/gp/product/B0000302Y8/
And the carbon dust is no joke, make sure you have breathing protection like this respirator. The bit can jump around, so a bit of tape is good to cushion from those markings:
