For those who track their GT3's on a regular basis and have replaced the coolant with distilled water (as almost all tracks stipulate), how do you combat internal corrosion of the engine?
I understand pure water is a better heat dissipater than a glycol mix, but has anyone checked their motors for corrosion / scale after years of using just distilled water??

you need to run a lubricant/corrosion protector such as Water Wetter or similiar
