Awesome runs Aaron! Cams seem like a logical next step. A used set of whatever brand 264's or 272's could probably be found for a couple hundo. Or if you have a set of spare stockers laying around, could send them in to get reground like I did on my Lexus, think they charged me like $250.
BC 280's for $250, maybe a little big for that setup though.
