2020-01-15 - Rear Fender Flares - Repurposed Material

I would like to continue our rear fender flares downward and create a mini-splitter in front of the rear tire. This would add more protection from tire-to-tire contact, as well as take the air off of the exposed tire. I would plan to re-use what's left of the package tray or what's left of our front bumper. I've attached pictures of the cardboard mockup and source material.

I also plan to cut the urethane rear bumper cover into strips for side skirts coming down off of the pinch weld. I will document this process.

It's my understanding that repurposed aero is 0-points, but I don't know if the continued fender flare will be allowed due to safety or another reason. Can you take a look and let me know what you think?

Looks good to me. Just document the source of the repurposed material and bring the documentation with you to each race
