After my first year at DE events I realized that I need to change the airflow over my car. I found an aftermarket duck tail in Florida, had it prepped locally and installed it along with a chin spoiler. That made a considerable difference to my track comfort.
Then, last year, I lucked onto a factory turbo tail from a '76 turbo Thanks Pat! It needed some work and with my new found skills from the VW project I was able to restore it myself.
Here is the tail just primered.
and then after base and clear coat.
and now on the car...
