It is simply a the best tool for the job in S/Gas. Why handicap yourself with an inferior tool if winning races, and championships is your goal. No different than running a dragster in S/Comp, its the best tool for the job. These days just about any serious dedicated racecar could easily run 8.90 but why not use the best available tool for the job. The long skinny car has proven to be the best tool for 8.90 classes just as the roadster has proven to be for the 9.90 class. Do door cars win in each class, sure in S/G some even do quite well, but follow the results and it is undeniable what the best tool in the shed is. I mean these days you can buy cars off the showroom that can run 9.90, in fact we have a couple guys with Demons that run S/G out west, they are just first round fodder but they are having fun and racing I guess, but really are just in the way. To each his own but if you are serious about running in S/Gas and consistently going rounds and winning races hard to deny the facts
