the srt 4 is supposed to have seats like the viper but some of them look like reguler seats with the head rest and some look like racing seats. does anyone know why?

They offered two different types of seats for the SRT-4. The highback, which are the tall Viper-style seats, and a lowback. They had to switch the seats if you wanted a certain option, but l can not remember which option it was. l keep thinking side airbags had something to do with it all too, but l am still not 100% sure.
