Street Stock Sedans look like "normal" sedans also but they are much closer to them than their Modified cousins. An SS sedan is basically a standard car with most of the road-going fittings removed. It has a roll cage but no other bar work is allowed. Engines are to be basically stock and very few performance modifications are allowed. Cars must run on street tyres and regulations prohibit extensive modifications of the running gear. As such, parity is much closer than in other categories and racing is always close. As it is a much less expensive category in which to compete, fields are usually large and as SS is a standardised category, competitors can race their cars pretty much at any track.
