Small update. The car has been doing well. 2 days at VIR, 1 day a TGPR, and 1 day at NSS
Drove at VIR on Saturday. The car really starts to feel light at around 120mph. Lucky for me, I purchased a Seibon CF hatch and a RE-Amemiya Wing from Fritz a while back and my dad and I drove up to his place Saturday evening to pick up that and some other stuff. Here is a video from RE-A testing the wing against no wing and the 99spec wing:
After driving 9 hours to VIR, driving VIR all day Saturday, going up to Fritz's and back to the hotel(about 2.5 hours each way) I was beat and too tired to put it on. We get to the track the next morning right before the driver's meeting. I come back and my dad has put the hatch on for me, that's what I'm talking about it!

Wing and hatch:
uhhh... I mean my girlfriend put it on:

The wing makes a very large difference. I was going through the first half of the track on the warm up lap and could really feel the car start to stabilize from 80mph and above. It progressively improves(obviously) with speed. I was expecting some front end lift at 120mph+ but haven't felt it yet. I'm sure it will with a little more speed. I have plans to put a splitter on the car as soon as I get some time. I also have the Rotary Extreme version of the RE-Amemiya street rear diffuser to put on. I don't think it will change anything, I just like the looks of it and I think it complements the Feed sides and the 99spec lip. Big thanks to Tim Benton for hooking me up with a really good deal on it as well:
