After retrofit-installation of the additional oem oil cooler, oil temps seem to stabilize at 230-240F under normal driving. Formally it would be at 245-250. I'm really curious to see just how well it would perform in the heat, so I will probably do one HPDE in the summer. My next event is in mid october, but ambients will definitely be at or below 50F. anyways, here are some pics:

Did you also consider going with a bigger core?

For me the oil temps - even with the AR Design oil cooler in front of the radiator plus stock oil cooler - were still too high. When I was driving really fast (i.e. more than 230 km/h for a while), it went immediately to 130 degrees Celsius (or slightly over that; 266 Fahrenheit). I've therefore upgraded the stock oil cooler with the VK Motorwerks kit and a Setrab core. Now the oil temps never reach 130.
