Do you have to much rear bias? I can't tell your entry speed, but it looks like you went deeper than I do in my Cup and your initial pressure might have been to soft and you kept pressing harder to get slowed down when the rears locked up. Your downshifts didn't seem to early, but might have been early enough to induce the lockup if the blips weren't good (hard to hear them on the video, if you have a auto-blipper, you might need a bigger blip.. the few times I ran mine I had it maxed out before yanking it off).

Hey Mike, I need to get your Cup car's set up specs for TH and LS for comparison. Will PM you
I still ask myself why from time to time. It has been a great learning experience

Here's a screenshot of T14 data in my car. I'm the red line, JvO is green. Your brake trace should look similar to get the shortest braking zone.
Also, remember the faster you're going the more aggressive you can apply the brakes.
As far as setup goes, it's pretty basic.. check out the IMSA GT3 Cup rules and put everything at the most aggressive. Starting from there, I usually just have to do slight tweaks to ride height and roll bars to dial it in. I use the same setup at Laguna, TH, and Sonoma -- normally just slight changes as noted above for track conditions or if I get a "funky" set of tires.
ps: double check your motec data and make sure the brake bias isn't changing throughout the braking zones. watching your video again, it really looks like you just have to much rear bias (assuming you have factory gear ratios).

Will look at the IMSA specs
by the way, these motec tracings are about just as bad as reading an EKG
