Oil recommendation for light track use-but hot weather.

Volk Z

Amsoil signtature series. 5W30. You asked about weight the starting weight is just the beginning weight the 2nd number is what it goes to after its warmed up so the weight would be the recommended oil 5w30 unless you have a turbo on there then a heavier weight may be needed (I.e 5w40)
I run the K&N oil filter it has a hex head so when you take it off its super easy. I coupled that with a magnetic add on that clips to the filter to keep all metal shavings in the filter and a Greddy magnetic drain plug.

Amsoil is the first in synthetics and I use in all my cars engines, transmissions and differentials. Google amsoil vs *any oil brand* and you will see it annihilates the competition.

As for the oil cooler, I have a 2013 and its great for street use BUT I'm not sure if it could sustain heavy tracking so you could run another cooler on top of it to be safe if you are worried.

Lastly, I used to live in Rancho Santa Margarita right next to Mission Viejo! My Dad still lives there! Small world
