Cryo treating anything is another JOKE!!!
What's not a joke. Big fat rotors but they a weigh a ton and require 18 inch wheels. I think my rotors are 13 inches which is fine (i have the brembo GT kit which is also my favorite) I buy the expensive high heat rotors from coleman racing and that's about the best you are going to do for the money.
If money wasn't an object I'd buy a super cool PFC brake kit

Of all the FDs I know of that have circled VIR very few crack 2.10 much less 2.05. Pete is one of a handful that are truly hauling ***.
For some perspective. I don't think a bone stock GT4 with a pro driver in the seat can keep up with Pete in his FD at this time.
Here's a pro driver in a GT4 running a 2.08 with DCS upgraded suspension and it was probably cooler out LOL

If you aren't tracking it, you probably won't have leakage, but then again if you aren't tracking it you don't need it in the first place.
I suspect it's just a cheaper, more porous casting.

If you suspect the leaking problem with the Greddy diff cover is porosity in the casting it would be easy to apply a coating to the inside before use like oil shedding Glyptal paint.
It does look cool.
The $120 RX-8 stock diff cover with the Aluminum heat exchanger extension on the side looks even cooler though in my opinion. It won't work with the HPP diff brace though.

I was smelling a little diff fluid while flowing Pete at the last event and I suspect his drain bolt on the stock cover is seeping just bit.
I'll repeat the fluid breaks down and becomes extremely thin and leaks out of the drain bolt.

If it leaks out the drain bolt when it is super thin/hot I wonder if you could substitute a wider shouldered drain bolt and then use a crush washer with slightly thicker o-ring in the middle like you would on a fuel fitting. Seal-o-stat style.
Like this without the washer-

However a little extra fluid isn't going to help you need cooler.

If the fluid is overheating to the point of breaking down and leaking out of the drain bolt I'd say NO!
A diff cooler is a must IMO if you are running consistent 2.10 laps or lower at VIR or 1.22 or lower at Summit.
Here I'm driving a mostly stock FD on stock wheels with hankook c51s (245 45 16s) and ruined the diff in a weekend. Car was running 2.10 to 2.14 laps all weekend (3 days).
Now imagine an FD with another 100 HP and 275 40 17 tires or worse 285 30 18s. You are really overheating the diff, trans etc....
Again that said most people tracking this car are not going to run 2.10 laps in even a heavily modded FD. See vid and the 1st lap is a 2.10.

Just saw this on my feed. He is definitely running the Greddy diff cover.

Weekend project:
Custom oil injectors with upgraded check valves. I found these that are rated to 125 psi, and have a .5 to 1 psi crack pressure.
I also found these perfect scoop coolers that fit together for diff/trans, allowing them to mount flat under the car.

While the glue is drying it was time for a little street to go with the track. Finally installed my charcoal alcantera headliner from Austin.
Definitely need to get him to do the visors too, but In addition to looking great with the alcantera pillars and center tunnel, im hoping it'll help with sound a bit.

So here's the test fit. I was hoping they would sit closer to the center by the diff, but the subframe to chassis brace gets in the way. It's less in the way the further left you go.
This is about as high as it'll mount, which would make it about as low as the lowest point on the subframe, or the plastic fuel like cover louvers. I don't want to run over anything and rip them out. I may have to split them apart and mount in two different places.
