If you are not doing track days I would stick with standard coolant/water mixture. It not only lowers the freezing point but also raises the boiling point.
I've found that standard green coolant will lead to deposits in the cooling system over time, but Volkswagen G12 coolant will not (phosphate-free and without the problems of Dexcool). I switched mine over to that. If you switch it, you must *completely* flush the system, because this stuff is not compatible with the standard green stuff. Available at any VW dealer.
If you ARE doing track days or racing, you'll have to check the rulebook of whoever is organizing them. Water mixed with WaterWetter is accepted everywhere that I know of, but Engine Ice may not be.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
