Welcome to SierraSierra.com, Online Home of Sierra Sierra Enterprises

Welcome to the Sierra Sierra Enterprises website. Our team was created with the singular, focused goal of achieving nothing less than race victories, championships, and course records. Sierra Sierra Enterprises has proven itself in the highly competitive Atlantic Championship Series, winning the 2007 Season Championship, and it is this same winning determination that we bring to the Time Attack World.

Our goals today are plain and simple, set and record the fastest time at any circuit that we compete at and at the same time help cultivate and grow the global time attack sport.
