We got a hold of the 2015 Formula Drift technical rulebook this morning which looks to be mostly the same as last season with some small tweaks. We have been digging into the rules today and ignoring the advertisements (yes, they added advertisements to the rulebook) as we combed through the technical regulations. One noted change in the rulebook has to do with seats. Below we have a full listing of the 8.4 seat rule found in the new rulebook. Do note that drivers will all have halo style tops, seen in the photo above, to protect drivers from side impact. Please drop us a note in the comments or via our contact page to let us know of any other rule changes you catch!
