get 5 packs of these.... unless you want a lock lug too... then get 4 packs and a pack of gorilla locks in a 14x1.5mm thread pitch.

i like spline lugs myself. which is what most of us are using with custom wheels. but they would stick out too far i think on a 300c srt wheel. just make sure you stick with Gorilla brand lugs.
