Never mind, did a google search.

 

curious if this is what you found?

 

Distilled water is the only additive I would use.

 

Repeating - Nothing but the coolant & distilled water mixture.

 

Yes, the Redline was what I was courious about, and I did find out it was not good.

 

FWIW, this product is recommended by LN Engineering along with their low temp t-stat:

I'd like to know what you found not good about Water Wetter. I've used it for years in cars, never an issue.

 

I use Redline and have seen a -10 Degree + drop in temp.

 

My local dealer was running a coolant flush special, so I had the radiators and system flushed and new coolant added. My next move will be the LNE low temp thermostat.
Living in Florida the cooling system is very important to keep up.

 

Good choice. I have a 180 Degree Thermostat and a GT3 3rd Radiator.

 

Ok, OK ..stop...where did you get the third radiator? I have a C4S and have been looking but everyone I ask says it won't fit my car. HELP

 

Vivid Racing installed mine when they did my Turbo Engine Build, they sell them on their website, Suncoast Porsche down the road from you has good deals too. Not sure if it will fit yours, I dont see why not though???
