This guy builds and customized a mini trailer for a Porsche track day car.

Track days are a huge part of gearhead culture, and while some of us prefer to hit the dragstrip on the weekends, our circuit minded brethren enjoy the twists and turns of any racetrack open to the public.

For track and drag enthusiasts alike, taking your racing tires and driving on them will wear them out rather quickly, and while drag radials are sometimes legal for street use, many people opt to carry their tires with them.
That’s where a tire trailer comes in handy, and if you ask the guy in the video below, it’s heaps better than a roof rack.
