Aux radiators do well in the wheel well as you mentioned because the air is generally cooler going to them unlike the main radiator that has to deal with the inter-coolers heated air and the condensers heat rejected from the cabin if your running a/c. For a small core sized aux radiator, it would be better to run the aux radiator in parallel with the main radiator. This is how the BMW PPK aux radiator works. It diverts some of the hot coolant from the radiator inlet to the aux radiator then back to the cold side of the coolant system.
You can run an aux radiator before or after the main radiator but the core of the aux radiator need to be designed and sized to allow all of the flow of the cooling system to pass through without being a restriction. For smaller aux radiators that is hard to do which is why they usually divert a portion of the coolant flow to them.
Another effective way of increasing cooling is to vent the hood. This will lower the air pressure in the engine bay allowing more air through the radiators.
What about maybe just running like the turbos return to an aux cooler then dumping back into the circuit, figure n52 doesn't really overheat so this would be getting rid of the heat from turbos and prob helping rest as well since dumping cooler water into the radiator ?
N52 has a much lower specific output and specific heat flux compared to a boosted N54, can't really compare the two I'm afraid...
I get that but I think a large amount of the heat is from the turbos I'm sure the extra fuel being burnt adds as well I am just wondering if taking the turbo heat out of equation and a little more heat while your at it. Big singles usually dont have same heat issues
The answer is to get rid of the stock snails and convert to ST. I know you said you want to stay with the stockers, but I t’s really that simple.
OR you should downsize your IC because that VRSF Race IC is waaay overkill for the stock turbos and is robbing precious space that would be used for cooling the radiator. I would also recommend cutting larger openings in your fender liners to allow the OC’s to breathe and you should also consider adding ducting to the oil coolers as well.

I had a revelation this morning. From what I can tell, the 1M/PPK aux rad uses the EXACT same core as the stock 135/335 oil cooler. Therefore, seeing as I have gone with a CSF radiator + N55-style oil2water cooler (thus rendering the stock oil2air cooler defunct), I will repurpose the oil2air heat exchanger as an aux rad, plumbing it inline with the water feed into the oil2water cooler for a bit more overall cooling capacity at very little additional cost.
