So far our testing data is telling us oil temp is kept under control for a manual transmission car under racing conditions. Autos puts more heat into the cooling system and take away some of the cooling needed for the engine, that will still need more testing.
Adding another oil cooler or upgrading your existing one wouldn't hurt and it will further drop your oil temps and prolong oil life.
