How much protection do I need? The car is Alpine White with a chrome grille. I later plan to install a matte black grille and install veil on my headlights and fog lights. I want the best, but I dont want to over-do it and end up spending more money than I have to. What would you reccomend as far as model and brand? I've heard LI is the best. Would I need a 2 head or 4 head? Do I need that new special edition system with the double diodes?
