I don't think you are going to find something "performance" radiator and hoses. etc... but I do know this you can add something called Wetter Water, or Royal Purple Cooler, which basically an additive to your anti freeze and it "wets" the metal parts and cools the temp lower by much as 15-20 degrees. Not sure if that's something you're looking for.

Unnecessary and a waste of money.

A slightly lower temp t-stat would be fine.

If your car is not modified, the factory items are just fine. Putting in a lower temp thermostat is more than enough for an unmodified car.

best extra cooling you could do, is auxiliary transmission cooler, which is only for the transmission fluid.

Unless your H2O pump is leaking, leave it alone.

Snake oil/water wetter anyone remember that?

here the thing, you definitely won't find a lower thermo stat temp since they are part of the water outlet assembly, I have not seen anyone carries a lower temp t-stat all you can find is OEM Temp

, Z33's have a lower opening temp, and there's always the Nismo unit, which is even lower. Or you can modify your stock unit as people have done in the past. Couple that with having a manual switch to your fans and there's your 10$ upgrade.

Water wetter actually does work but that's for racecars.
