The racers and participants in both events are very special racers. Not many racers in the world can do what these guys do. Take ,sometimes six digit value vehicles, and get them somehow down the track without spinning the crap out their Polyglas tires. whichever event you chose, you will be treated with respect, admired by many, race with the most elite "showcars" in the hobby, and treated to some of the best parties at any car show event in the world. Not kidding. Both classes can really make the new guys feel like brothers, and all"tricks " are revealed.. The tricks are just options the new guys were afraid to ask about. All mods are openly talked about. In my humble opinion, I love the idea of racing showroom racecars, able to beat stock "showroom racecars" of present times..
