All-new rear brace is smaller plus the mounting position on the framework is relocated for a brand new framework flex point position. The mounting of chassis brace to the bulkhead eliminates the transfer of power from suspension system via surprise towers to make sure more precise landings and more off-power traction.
Molded from a MEDIUM-stiff composite combination for improved flex & rigidity. Allows the mounting of optional graphite inserts to bolster the framework brace to make it even stiffer for particular track conditions. Fits just XB818 and XB8E18.
