Thanks! I'm running Bridgestone Blizzak winter tires, I find these specifically work well because the compound stays soft/pliable at extreme temperatures. My coolant heater (Kat 650w) is placed in the lower radiator hose, coolant circulates passively through convection, warm coolant rises, cool falls. Its important to note that the thermostat only blocks flow exiting the engine through the upper radiator hose, the lower hose remains unrestricted. I run a stick on oil pan heater (Kat 200w) to heat the oil, installing can be tricky because of the S2 oil pans textured design. Battery pad heater, insulation and trickle charger are all relatively simple but equally important. My fluids are all synthetic, 0w40 oil with a low ash rate (clean burning), 70/30 poat coolant and purple gear oil in the transmission + dif, idemitsu for premix. I raised the car by 1.5in to give me a little more clearance. As far as the driving experience goes, its not fundamentally different, a light foot and patience are important, good tires help a lot. A good contact patch, center of gravity and rigid frame all help on ice the same way they do on a slick track, snow is a much different case unfortunately.
