I will be getting some logs on my track day this week so ADE can recommend an upgraded oil cooler, which will be installed with a bypass plate in place of the stock oil thermostat housing, larger lines and externally adjustable thermostat. The stock thermostat and lines don't flow enough to support a significantly larger oil cooler, and the external adjustability will let me dial in street and track settings so that oil temps reach target on the street without overheating at the track.
I can't help but wonder if a larger coolant radiator may also suffer from limited flow reducing its effectiveness.

I am not aware that there are any kits out there. I just had my aux radiators custom made according to a hand drawing. Total cost was less than a new CSF rad, but Im in China...
Attached is the family picture. One sits at the normal aux rad location, the other sits below the main radiator behind the FMIC.
I dont think you need to worry too much about the hose ID. I did up-size a bit because someone recommended that, but on the 1M I would just use the OEM hoses in order not to run the risk of breaking any plastic fittings.
