Racers have asked for a more durable option for the steering bell-crank arm on the B74, and JConcepts has responded. The 3.0mm thick carbon fiber material is durable, light-weight, and features milled sections which help maintain strength while minimizing weight. The mounting pattern has been slightly altered to optimize durability. The steering bell-crank arm features ribbed sections and chamfered edges on the surface of the exotic material.
