Those temps are fine and well within oem cooler's capabilities. Just shorten your oil change interval once you're doing more tracking days.

Once you're constantly getting redline reduction (needle is close to 300) then it's a necessity. At which point you'll probably want to upgrade the trans cooler too if you're DCT.

DO88 is preferred oil cooler and trans cooler. CSF for everything else.
