I noticed that in the video you made of your incar video at the race track
My son Creed works for a giant of a company that builds engines for JD, rail way componies and such, and he has found something like cat/ kitty whiskers.
Let me call and see if he can get us 40' of it on the cheep or even scrap ends, they are used for dust and bugs on generator packs for trains.
If (and it is likely) I can get some for free they are free to you as well.
