Singular Vents Now Illegal NASA ST/TT 4/5/6
PSA.
Other vents may be affected as well. If you feel inclined, maybe with enough backlash the rule will be revised.

Quoted from your link (emphasis added by me) :
I just went out to the garage and measured my Singular vents, and the vents themselves are well under 3/8". Simply removing the 'gurney flap' should bring them within compliance...??
ST4/TT4
1) Conversion from coil spring to coilover shock spring configuration is permitted.
2) ST4 Aero— Hood Vent lips/louvers/vent insert mounting hardware must not protrude more than 3/8” from the hood surface.
3) Front Splitter maximum thickness is 3/4”
4) Rear wing end plates maximum size changed to 144 square inches.
ST5-6/TT5-6
1) ST5-6 Aero— Hood Vent lips/louvers/vent insert mounting hardware must not protrude more than 3/8” from the hood surface.
2) Front Splitter maximum thickness is 3/4”
3) Rear wing end plates maximum size changed to 144 square inches.
4) Final drive gears in FWD and “transaxle” vehicles are unlimited.
5) Subframe connectors beneath the floor are permitted with the addition of a torque arm.
Note: Enforcement of the Hood Vent rule change will begin on June 6, 2019--See Technical Bulletin

Here's my measurement of my gen 1s
Such a random size to pick..... it's like they wanted to exclude the vast majority of louvers. Did they even look at ANY CFD data or any data at all to make a decision? My guess is no.....
It's not that hard of a fix for me, but it's really frustrating for a random rule like this to be put down mid-season. Building up more of a negative reputation ultimately losing current and potential customers.

Also measured my endplates on my Singular wing kit and those are illegal now as well and need to be reduced in size. Mid season baseless rule changes are an excellent way to drive customers away.

NASA as a whole is tough for rule changes. Seems like the rules are in constant flux. Power to weight ETC. Just be happy you're not one of the GTS guys that builds a car to compete in a series then NASA pretty much destroys it. Spec Miata is the safest bet but even that has some expensive changes like the recent Penske suspension upgrade.

That is what they say the intent of the rule was but it's definitely not the way it was implemented, since there are so many cars with illegal vents even though Greg stated that he "thought would be legal" to me in an email. Which proves that the measurement they chose was pretty much pulled out of their *** and now they're trying to defend the number they chose.
Two different polls on FB with dozens of people answering them show about 60% of cars in class are affected, about 25% have no vents, and the last 15% have vents that are already legal.

Here's a good opportunity to show NASA how people feel.

I originally had my car prepped to the limits of TT-E standards, and that class was done away with before I could set rubber on a race track. No skin off my rear end. I then decided to target TT5 or maybe TT4. Now my hood vents (Singular Motorsports) that I installed on my 1991 Miata, with good faith to the rules are "illegal" unless I go to TT3. I am now second guessing staying with NASA Arizona for the simple fact that if mid season rule changes will be common place, I may not afford to be able to keep up with them as I view this as a slippery slope type of an issue. I have a decent amount of money tied up in my car, and I have tried to build it per the rules. However, if NASA deems fit to loose it's s*it over (in my mind) piddly stuff, I WILL seek another racing organization to run with. I have had an absolutely AMAZING time with NASA, but this is very disheartening, and in my humble opinion, almost unacceptable. I understand the spirit of the rule change, but it must be made more reasonable to accommodate off the shelf options for a Miata as well as other cars that have the same options. 3/4" would accommodate almost every off the shelf vehicle specific solution available. I feel that I am one of many frustrated individuals affected by this new rule. I wish to continue my relationship with NASA in my region, but I am personally unable to afford to change my vehicle mid season. I hope that this does not fall on deaf ears, however, I will defer to the judgement that is above my pay grade. At the end of day, competition must be fair, and rules must be adhered to for the sake of everybody involved. However I feel this is a knee jerk reaction to a problem that is being blown out of proportion.
