my 2011 WRX was past 60k miles so i flushed the old coolant and put new Subaru 50/50 Super Coolant along with Redline Water Wetter. subaru 50/50 super coolant + redline water wetter = killer combo for spirited/quick driving on street and highway.
Great stuff for the track!

When I road raced superbikes with the MRA I used this stuff in my HondaCBR600RR and I plan on continuing to use it with my WRX for track days! This stuff is amazing! Most of the tracks I go to don't allow you to use antifreeze incase it gets on the track. With the water wetter, it's a drastic cooling difference over straight water, especially on the hot days. Easy to mix, just follow the directions on the bottle! I will add that during the winter I drain my coolant system and go with Engine Ice antifreeze with 1/2 the recommended amount of water wetter in it as I'm not on the track during the winter months.

i use this with straight water for the track, it cools better than Glycol, & trust me when I say you don't want anti freeze going on your back tires on the track!! other drivers will appreciate it also. you just have to remember it offers no freeze protection.
QUESTIONS & ANSWERS
Q: How much? justinpozzolo53115 5 years agoAnswer
Ok I have a 2009 sti with the koyo radiator. How much would I need? I drive in really cold conditions so I cant use water..just coolant. Can I mix this with straight coolant? Do I even need this?
A: 1 bottle will service a entire system. As for your vehicle, you do not want to run straight coolant as it causes issues with thermal dissipation. As contrary to the name, 100% straight coolant with no water has very poor thermal dissipation properties and needs to be mixed with water. Follow the instructions on the coolant bottle for proper mixing for your vehicles operation conditions.

Q: Mixture sphillips.islreal73402 5 years agoAnswer
So for optimum cooling efficiency do I mix this in equal parts to water? So if I use 1 quart water wetter with 1 quart water?
A: Redline recommends 1 ounce of water wetter for every quart of water for maximum efficiency.

Q: Proportion m1k1e20175 5 years agoAnswer
How much would i need for a stock STI 09 and the Koyo Aluminum Racing Radiators? What would be the optimal proportion? As I understand I can mix it with either water or coolant?
A: Redline recommends 1 ounce per quart or 1 bottle for cooling systems with capacities of 12-20 quarts. For optimal cooling you can the same proportion with water only. This WaterWetter will work with water or mixed water and antifreeze.
