bottom line is if the car came smoothed from the factory or J-spec everybody would have no problem with it. just cuz people want to be different and change the style its not good. its just that people are not used to it so it looks wierd for a little while and then it becomes more normal when they see it more often. sports cars have no body lines. they are all smooth. and a million other cars on the road have no rock guard and they do just fine without it. none of my other cars have rock guard and they get driven way more than the Z and there are no chips.
