Personal semi-edumacated opinion: Your problem is your oil cooler location. The air is just going to go around it, rather than through it, as the path of least resistance. It is also heavily shrouded sitting behind that bumper cover. I would think that it would work better at the back of the "vee" as long as the sides are sealed between the radiator, oil cooler and intercooler and you have the front sealed so that all air from in front of the car is forced through the box created by the radiator/oil cooler/intercooler. ...awaiting other opinions.

"BEST" requires:
1) Aftermarket bumper (or mod stock front bumper) for larger holes in bottom corners
2) 2 oil coolers - left and right
3) Required plumbing to make it all work

Assuming you're happy with your current water & intake air temps on the V-mount setup, and you don't want to change any of that, I think Ted's idea to switch to dual oil coolers in each lower corner, with the proper air ducting via new/modified bumper to deal with oil temps makes the most sense.

The oil line plumbing for that may be a PITA, and then the next question would be is it better to plumb the dual oil coolers in series or parallel?

The car is not supposed to be getting that hot (on oil temps) on the street...

Aftermarket oil temp gauge?
Can you verify the temps?

If your oil temps are indeed overheating on the street, something else is drastically wrong...
Do you still have an oil thermostat on the system like stock?
The stock oil cooler should have no problem dealing with anything you throw at it on the street, unless you don't drive under 4kRPM's...
