[GT40Racer]

There are in every club some quite serious 'racers', and there are some who will still try to get around the Rules/Regs of each Class and who will use every trick in the book to have an advantage over everyone else.  This can go to the extent of shaving the bottom of the bodyshells and cropping the body mount posts to get their car lower to the track, or...using slightly smaller or larger diameter wheels and/or lighter mag wheels, or changing pinions, or even re-wrapping motors, or swapping the motor magnets and even the armatures etc etc. I have seen them all in my time at one club of another.  Class Rules/Regs are there for a reason...to make it as level a playing field for everyone as possible.

Do you race with our club? Sounds like you could. Your forgot to add painting the motor :) - At our club it has got to the point where basically I don't have any interest in racing anymore. I check to see who has indicated they are attending and if some racers are going to be there I do something else with my time.
