Currently working on a S65 - Active Autowerke stage 2 that sees the occasional track time. Mostly street driven and gets pretty warm here in southern California.
I also installed ALL the CSF coolers with minimal improvement.
Based of your feedback I am going to do this same mod. Thank you for sharing.

In cooling related information : I installed a 160F thermostat from a Dodge Viper.
Part number # 880060 (Motorad brand)
The part number will list S65 & S85 under the description along with V10 engines from Dodge. Perfect fit and coolant temps dropped about 15 degrees. Better recovery time on the cooling fan as well.
