Bulkhead brace made from premium graphite material. Allows easy access to the engine screws, and gives 2 different flex characteristics to choose from to easily adapt the handling of the car to particular track conditions and tires used.
SOFT:
Graphite brace not used. This allows flex in the rear suspension and generates more rear traction. Recommended for low-traction tracks, or races with spec hard or large tires.
STIFF:
Graphite brace is connected to the 2-speed bulkheads. This setting reduces flex in the rear suspension and improves out-of-corner steering & rotation, but also slightly decreases rear traction. Recommended for medium- to high-traction tracks, or when tires with additive are used.
