Rules & Regulations

How about a kind of standard regulations for these Credit Card Racers? I'm a great fan of the "no limits, no rules" formula of the legendary Can-Am series. So here's my proposal for Credit Card Racers' regulations.

Only one credit card (or similar plastic card 54x86 mm) per chassis may be used. Just cut, fold or take away material. Cut-off material may be added again by gluing.
Overall width: the width of the credit card (54 mm)
Overall length: limitless, as long as only one credit card is used.
Overall height: free
Weight: free
Motor: free, attached by glue on the chassis
Gears: free
Axles: free
Tires: free
Guide: free
Magnets: no
Lead: yes
Type of body: free, but the body has to cover the entire chassis and all other mechanical parts when seen from above. Driver figure/interior and starting numbers added.
