Those 2 seem to have a lil flatter hood or over rounded bumber. Either way the hood curls up at the corners.

Its worth noting that one of the red cars posted here didnt have that problem! (at Royal Oak)

 

The cars that you see are still very likely IVER or even test mule cars with a much higher level of assembly and finish, but still are no where near reaching actual production fit and finish.

I believe that the 1993 Camaro was one of the first (if not THE first) production vehicle to use laser cameras to measure body fitment, etc. While the quality then is not as good as it should be today, they wouldn't allow this car to be worse than 15 years ago.

 

To the best of my knowledge,their will be 2 different front bumpers,Standard bumper,and the SS bumper.The SS bumper will have somewhat of a bodyline from the foglamp and then wraps around to the bumpers edge,also the SS will have the "mail slot"at the top of the bumper,but the standard bumper will not....as far as i know,so don't quote me on this.Both the red and yellow camaro's you see are RS optioned LT models,not the SS

 

the lack of the "mail slot " gives the front end a more "clean look .
