Modifying and adding a rear trunk spoiler!

[ronmanfredi]

At Mustang Week Texas just a few weeks ago, we won an award for our 2006 Avanti being there.  The event also gave me the opportunity to see a lot of different options for the back of our car.  The Avanti trunk and rear fenders are completely unique when compared to the same year Mustang but the ideas you can get from seeing all the custom designs were incredible.  I now knew that I wanted to add a rear spoiler to the car and this would be #1 of 2 changes that I’m going to make to the back of the car.  I also knew of the complexity of making a 1 off piece, so I wanted to find a premade fiberglass spoiler that I could modify to work with the multi curved trunk.  I bought and returned a couple spoilers that just wouldn’t work. After returning the last one, we had a chance to go to a large monthly car show in the Austin area.  As I looked at the back of many different model sports cars, I noticed one that had a back end which was about as flat as our car.  The other thing that I noticed was that some of those cars had flat top mount spoilers, edge mounted flip up spoilers and pedestal mount spoilers.  Flat and edge mount were out due to the arch at the top edge of the Avanti trunk, but the pedestal mount was promising.  I took my iPhone tape measure app and measured our car and the car that looked like it might work and holy cow, the width was within 1/2” of each other.  After eyeballing the fender angles and spoiler design, I knew I had the car.  2016-2023 Dodge Challenger!  The next day, I located an aftermarket factory design Fiberglass spoiler that was primed and ready to paint, so I ordered it.  Once arrived, it was time to decide where to mount it and how much modification it needed in order for it to mount correctly to the Avanti trunk. I basically had to add 1/8” to 1/4" of fiberglass to the edges of the mount of the spoiler so it matched the curvature of the trunk and so that the edge of the side of the spoiler was gapped to the fender correctly.  Here it is:
