I have an additional smaller Front mount SST cooler from Mike@RRE.
Replaced the stock one with bigger cooler (also from Mike@RRE).
Plus SST tune by Bryan@GST/Razorlab
When I had taken it to the autocross, I limit my rev to 5-6k rpm.
Granted, it is not triple digit speed like road course track but I drove it relatively spirited.
I never had a problem with over heating issues.
I also turn my heater on during spirited driving to help cool things down in the engine bay.
I had driven my civic wihtout a/c for 10yrs of summer, so Im used to the heat some what below 90-100 degrees.
