250 isn't nearly 280 (limp mode)
I think your fine with your oil cooler.
Switching to water and water wetter coolant for the track season it the only think I would say you might consider.
The 2011s don't have the same pressurized coolant system as the 2012+ models. Not sure what pressure each version works at.
