All of the 5 "Brain Buckets" Ken Block had designed, decided to do this one for 2 reasons, 1.- He used it in one of my favorita cars he had the Ford Focus RS RX, and 2.- He filmed that video using this specific helmet in Guanajuato,México. And im from México, living 1 hour away where he rallied with that helmet, didnt had the chance to meet him or saw him rallying tho...
It was hard to do this one, these are limited helmets and there was no much references out there apart from a couple of pictures and a video he uploaded back then explaining the buckets, so dont expect to be a perfect 1/1 representation.
