I was having the same issues on 90+ degree days. What finally resolved it was a combination of multiple things:
- Upgrade oil cooler core to 40 row. It is not necessarily a direct fit as some trimming and creative mounting had to be done.
- Trackspec hood vents
- Trim bumper opening to allow more airflow.
- Mild ducting to force air to go through the radiator and oil cooler
- Water wetter
So far this has been successful for me. I have not yet tried a track day with triple digit ambient temps, but 95 degrees with hour long sessions have not been an issue. Water stays dead center and oil does spike to about 245 but no higher.
