How to Install a Carbon Fiber Rear Diffuser on Audi S3 8V

My fellow Audi S3 Fanatics, after a ton of request to create this DIY, I finally found a local subscriber to volunteer his car for the task. A big shout out goes to Steve W. of Orange County for graciously loaning me your S3 and helping with the install. Thomas, at EMD Auto needs the proper credit as he shared with me his experience for a successful and proper installation.

As many of you know, it’s been over a year and a half that I installed my carbon fiber rear diffuser. At the time, I rushed while recording the DIY and did a poor job during the installation. Technique wise, it was also performed improperly. Today’s DIY will focus on the PROPER way to remove your OEM rear diffuser, and replace it with an aftermarket CF one.

There will be four main parts:
removal of rear brake lamps and trunk interior panels
removal of the bumper
removal of the OEM diffuser
installation of the new CF diffuser

Once the diffuser is successfully installed, you’ll just back track and re-install the bumper and other components. It’s a DIY that’s a bit more challenge, but 100% doable. I highly recommend having at least the rear end up on jack stands, and having a friend help.

If any of you are local to OC and need me to do the work, let me know and I will gladly install it for you! As always, thank you for watching and supporting my channel!

If you also have a vehicle you would like featured on my channel, let’s get together and talk!
Until the next time, this is Peter, The Audi S3 Fanatic!
