Picture below of the Smart Cross Wrench in its own pack. There is only one variant but here's the part number anyway - 00B 060 A. Available in any colour so long it's Cusco blue.
Removing the wrench from its packaging also reveal a freebie Cusco sticker. Cusco claims the cross wrench is 100% made in Japan.
Disassemble the cross wrench by sliding the inner chromed shaft from it's blue coloured outer sleeve. Cusco claims material used is chromed molybdenum (steel I presumed). Dimensions are 400mm X 400mm. Torque capability is 450 Nm.
Below's a picture of the cross wrench with my Rays Engineering Duralumin lug nut which uses the 19mm socket. The chromed shaft should go all the way through the blue shaft to form a "+" instead of a "T" in the picture for more leverage. More details on using the cross wrench can be found @ Cusco's website on the Smart Cross Wrench. You can even watch a video of it courtesy of RallySportDirect.com here.
