What would make the oil not suitable for street use?
The ZDP levels are very high and TBN isn't that high. You could run it on the street but it wouldn't be good for your CAT and it isn't designed for longer drain intervals.

Additives. It is designed for one purpose, racing. Street oils have to do much more stuff. Drop your kids to school, maybe not achieve operating temperature that often etc. Street oils have better detergency, lower oxidation etc. Street oils on track are always better than racing oils on street. Now, If I had M3 E90, and was beating it around track every weekend, this looks like fantastic oil!
 
I run this oil in the summer and drive it on the street because…I’m not made of money and time to change it before/after track days lol.
Just a note that this oil NEEDS to get hot to work properly, you’ll notice it your first lapping day. Another note, on track my oil temps were lower by 5C peak.

For comparison, street oils FAILED my car, destroyed my lifters and cam. RACE oils like Dominator and ZRod (more street there) have been the solution to the issue. I’ll create my own post because it’s an interesting case study but a lot of people on the forum are not well read on what it takes for racing.

What car are you racing and using as a daily/street use? I don't see your separate post anywhere? What oil are you comparing with the Dominator for the temp drop?

I’m working on it. I work a full time job and I run my own business (another full time job)…and I volunteer with Motorsport club of Ottawa…and I’m a volunteer medic with St. John ambulance lol.

I’m comparing against Amsoil full saps 5w-40 euro, Amsoil signature 5w-50 and Amsoil Zrod 10w-40. As well…Castrol euro 5w-40 when my local shop resealed my oil pan after a rear main seal replacement.

This is racing a Fiat 500 Abarth with the 1.4L multiair engine. Very few race then nearly as much as I do and so they don’t bump into hardware limitations like I do. The Fiat community is mostly cars and coffee attendees so their car only needs to survive a couple of WOT pulls. As you and I both know, you leave some room (back pressure/EGTs when racing on track unless…you don’t mind going kaboom). This is partially why I professionally entered into tuning. The race track has no room for B$, so you get to test out myths and theories all the time.

When I dialled into the fact that “spec” doesn’t include running twice the back pressure and sustaining 1.5x the expected EGTs, I went down the rabbit hole of selecting formula for a particular usage (within the Amsoil product line). For an aside, I might try HPL 5w-40 DLM based on Dave’s recommendation. I’m still waiting for ADV to reply to my email on pricing.

Side note. With how many people are on here for oil, I shall invite you to look at WPC treatment, especially for valvetrain.
