I've been trying to make a MOC of the Lego set no 42156(Peugeot 9X8 Le Mans Endurance car). Specifically, a Rally car, because why not!? But seriously, I need help with the design. I tried refering to the instructions of the original Rally car, but have found nothing helpful. Maybe as a challenge, could someone design it? Or does anyone have any suggestions? Thanks a lot!
