FMX, back in the old days, hotrods were made to be faster, there were also few laws for safty restrictions, they started hackin' anything that didn't need to be and getting rid of it, many times, interiors, brakes ( who needed them back then, no laws agens't not using brakes ), this is essentely how hotrodding got started, people started hacking the old cars up to make them lighter and theoreticly go faster. 1 of the first hotrods, if not the first known hotrod was a Model T Bucket, which is a model T coupe that's had the roof cut off at the beltline ( now the aftermarket makes fiberglass and steel reproduction T bucket bodies). ( think that's what it's called ), then a big engine was installed. The choppers were born the same way, lighter faster, better rule applied, people hacked up old harlys. The truth is, they actully wanted there cars like this cause, they wanted the lighter faster and quickest cars to win street races.
