what i listed isn't even necessary for intermediate (you just need to change coolant to water wetter and distilled water, and RTV the oil drain bolt and fill cap). however, if you're sure you're going to be serious into track days, those are things you might as well do. for racing, there's just a bit more to wire (brake bolts front and back, axle nut, and some other stuff). and you need a belly pan. TECHNICALLY, that is what's required. but i'd highly recommend getting full race plastics, sell of your OEM plastics for decent money, and spend it all on tires and fuel lol
