I've had the motorsports shop where I had them installed check it over several times, but they can't seem to find anything. I took it to Toyota, and no big surprise but they blamed the coilovers saying everything else that was Toyota parts looked fine. At this point it's getting worse and I just don't know what to do. I almost want to just swap back to the stock suspension to see if it really is the coilovers. I reached out to BC Racing earlier today via email but they haven't gotten back to me. Wanted to see if anyone has had a similar issue to this, and if so what they figured out.
Here's a video. The little thumping you hear is the sound in question.

Well, that has to be an irritating sound while driving your car.
It's the weekend - maybe BC racing will get back to you the first of the week.
Back-in-the-day, I would guess you had part of your exhaust system bumping up against something. Easily fixed with a piece baling wire.
Maybe the sound is being made by a wheel or brake part and not the suspension. -
I'd suggest you take it into a different auto shop, take the tech for a ride, then ask them to identify and fix whatever is whacked out.
Reminds me of the day that my younger brother had this 1954 Chevrolet. He asked me to take a ride with him to see if I could figure out what was making the noise. Just after we pulled out of the gravel lane onto the paved road, I yelled "stop the car" and I got out and discovered one of his wheels had
all of the lug nuts just about to come off -
