What do you mean "you feel it"? Do you feel it in the steering wheel(jerk one way or the other)? Or is it that the cars suspension seems wrong? is it accompanied by any bangs or clunks? A GTP will have a stiffer ride then a concord, it after all is a performance car, and the concord is made for old people to drive to church. =) If you are worried about the struts bounce each corner than stand back. If the car continues to bonce more than or two times your struts are worn. If you hear them clunk when you bounce then the upper mounts could be bad.
Just sayin....
