I must diagree with the theory that the heaviest drivers should be used for the skidpad event, and this is why:
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Weight transfer is one limiting factor in the amount of grip a car can generate with its tires. The friction force a tire can generate increases as the load on it decreases, but not as fast as the load increases. In other words, the coefficient of friction is non-linear. A lighter car on the same tires will be faster than a heavier car with identical suspension geometry and power-to-weight ratio. In a turn, the lateral acceleration transfers weight from the inside tire to the outside tire. The grip generated by the outside tire increases, but not as much as the inside tire's grip decreases. So weight transfer decreases overall grip. ~ "Balancing Act" by Dan Barnes, p.92 of March 1997 Sport Compact Car<HR></BLOCKQUOTE>
