I don't do it... but there are a lotta people I know who only make it to a couple events a year and techincally should be in a class that won't let them compare to what they should be comparing to. Usually these people aren't close to being the fastest. Now if it was one of the faster cars, then yeah definitely be in the right class.
There was a car that ran with 60 treadwear rated tires in STS once. I let him know that they weren't class legal, but also told him it doesn't really matter, since he wasn't near the fastest cars and is not a regular to our region.
Maybe I should start running SM, because here the SM cars are slower than our STS cars and I could easily trophy.
But I'm not, because I like to run in a class that was designed for like cars.
