I also recomend using HPI's alloy spur gear mount #100670 and a quality spur gear such as one from Robinson Racing as they spin more true and are stronger. Besides that a thicker viscosity grease in the front diff to make the steering less "darty" for oval would probably be a good idea. Don't forget to play gith your camber link length with mounting locaton and droop settings, they affect your roll center and weight transfer.
