in really hot weather you can run water wetter + distiled water only as per evo sport instruction on their cooling system.
you can always flush it later for winter use to add the anti freaze mix

Never did MB antifreeze in mine. Only did Watter Wetter and Distilled for the summer. Runs great but yeah, gotta change up for winter which can be a pain.
Worth it for me in these heat monsters.

I just ran with the directions on the bottle. Running roughly 1oz per quart of distilled bro. Perhaps a tiny tick more.
Not sure what would happen if you actually could run a 50/50 mix of water wetter and distilled. Might not be good for the system and dayum that would be expensive. Don't be confused when they talk of 50/50 and water wetter online. They are talking about a 50/50 mix of coolant and water, then adding a few oz's of WW.
I have bout the same setup as yours and car seems to run okay with it. Never think you are gonna get the car to perform like you want on a hot sunny summer day though Killer. Just the main flaw in the beast.
I would be curious to see how cool even the mighty SLR coolers would keep it on a 90f summer day.
