1) Ensure your A2W pump is working properly.
2)Ensure your rad fan is working properly (important on slow sections of the track).
3)Verify that the engine cooling system thermostat is opening fully (may require disassembly to verify)

If all of the above is working as designed, maybe consider upgrading Engine Radiator and Oil Cooler, so it is better suited for your climate. Contrary to what some of the others have said, a larger radiator and oil cooler will not just prolong the inevitable....... Given adequate cooling area and airflow you can cool any size engine of any output. The key is cooling area (size of rad in square inches and number of rows). There is a reason why the large diesel engines I work on making 3000+ Hp and 10,000+ Lb/Ft use rads that are 10 ft high x 8 ft wide with 4 rows of tubes.

P.S. most large Diesel engines use liquid to air charge cooling due to more consistent IAT's and being able to do more cooling from less overall cooler area due to the added heat transfer abilities of liquid to air cooling systems. That is the reason why BMW is going this route now...... More cooling with less space and consistent charge temperatures to better control emissions and fuel economy.
