Does weight matter? Since these are gravity sports, being heavier will make you go faster. So there are maximum weights set to ensure a level playing field. Skeleton players can add ballast to their sleds to get closer to the maximum. In luge, the lighter athletes can wear lead so that everyone weighs the same. The runners and blades must be kept at a certain temperature, since they'll go faster if they are warmer. They're kept at approximately the same temperature as the ice and are measured before the runs.
