This is exactly why... for me, when I prepare for events, I often like to have at least 2 options for each class. This past event, I had brought one spare car (my LM) which was the reserve car for both stock and superstock. I have always had a decent fleet, and the least amount of cars that I bring to a race is usually 5 or 6. When a car works well, you don't want to change it to try something else.

now that I am out of brushless cars to adapt, I need to start rebuilding brushed cars for my test cars as I cannot afford to buy moe brushless equipment.
