s4 and s5 body differences, i have searched...
 

i just needed a little bit more detailed answers on this on the body. minus the moldings, front and rear bumper and taillights are everything else the same on the s4 body and s5 body?

ex. are the fenders front and rear the same? is the side of the car the exact same for both models? or is one wider then the other etc.... i just need to know those answers thanks.

There are a few other differences like mirrors and wheels. The bumper also has rubber between it and the fenders on the s4's.

but how about anything else like fenders or the side etc.. are they different

There are a few other differences between the models offered in different countries.

but my question is this are other body parts different as in front fenders, rear fenders? length of the cars?

...length of the car is the same, fenders are the same (as far as I know), rear fenders..there aren't any, it's one big piece. Cut and weld.
