I still haven’t received mine but my intention is to run the NLR on an, already purchased, flat trunk lid (with their largest end plates). Meaning, I won’t have the 1LE spoiler. In contrast, it seems you have the 1LE spoiler plus a gurney flap on the spoiler. I do wonder if that negatively affects your wings performance. There are also examples of cars with both wing and spoiler so I don’t think there’s a definitive answer on the matter.
Btw, I also have those small dive planes waiting to get installed. I hope to get this all running in the next month and then put it to the test at Laguna Seca.

Just a seat of the pants feeling and it just didn't feel like the amount of downforce the chart was saying. I don't think it was way off but I could add a couple of degrees and the front/rear ratio was off per the chart but it felt better on track. I also don't think their chart is car specific but wing specific so maybe the car has an affect on those numbers also.
Yes, I kept the 1LE spoiler but eliminated the spoiler gurney flap and it's just the bolts you're seeing in the picture. I also wonder though if that spoiler is adjusting the effect and that's why it's a little off for me, good question and I don't know the answer. You'll also be surprised how much the wing moves the trunk around at speed, I adjusted the trunk bumpers and added some thick weather stripping to stop the trunk from bottoming out and creating a line on the top of the bumper in the middle.
I've had the dive planes on for a couple of years now and they held up well. I did have to put two small rivets on each one for them to stay on at high speeds so you way want to do that also for track use.
All in I still consider the NLR big wang to be the best bang for your buck aero and you won't be disappointed.
