Was hoping to get the dimensions of our stock cooler, so that maybe we can find something we can adapt to have it in the stock location/stock size. I figure we can get more efficiency out of the package, but keep the car mostly stock. Plenty of people are tracking without issue, so it doesn't need to be a huge upgrade, maybe just a more modern/efficient cooler with slightly more capacity.
That's why I went with M6 oil cooler, it adds almost a liter of extra capacity , yet with a custom bracket , fits in the OEM position without any cutting/ trimming or blocking of the radiator . Now on track my avg temps have dropped 40 degrees which is huge as far as increasing the engines lifespan . Not going into limp mode from high oil temps doesn't mean you are not having issues related to high oil temps. I never had a temp limp mode on track and look at my bearings. Increasing the oil cooling capacity was the best mod I have done .
