anyways, what mods have you done to your Accord? The stock 4cyl would be in H Stock (HS), while certain mods will move it up to Street Touring S (STS). A more modded Accord would be put in F Street Prepared (FSP). Mine was put in FSP because the club that hosted the auto-x wasn't running the STS class. It would have been in H Stock if I had put my 15s on, since the Accord is still stock...
