but beyond that I don't know what the go is. Maybe its just an engineering thing still. They can make the most out of the mould with G2 and Stepper, oh, just thought of this, Martini labeling on the original may stop them, they could alter it, but if its specifically based on their racecar then like Exhaust it would need modifications to the livery at the least.
