CRG is a manufacturer of components for the motorsports industry. Whether it be rear sets, mirrors, or levers, all the pieces are manufactured utilizing CNC (computer numerically controlled) machining processes. All parts are cut from solid aluminum billets. They make all of their own parts in house. Making parts in this fashion is not the cheapest way to build them, but it is the way to produce a part with a high degree of precision, and finish. For this reason, CNC machining is the process chosen by builders in all forms of racing.
