Im looking to get the factory underbody kit , but for the life of me scanning through pics after pics I cannot see the difference between the stock side skirt and the upgraded skirt that comes with the kit . I was going to just purchase the front and rears to save money if theres not mush differences on the sides. Anyone with the kit, can you pinpoint the differences between the two?

 

Very slight difference with the sideskirts; less than half an inch.

You will only be able to tell (if you really stare at it for a long time) if you have the front and rear kits with OEM sideskirts. There is a slight concave appearance. Otherwise, they're pretty much aligned...

 

it protrudes out more. when i initialy got it~ i kept on steppiing/kicking it whenever i stepped out of the car, but i got used to it. height is the same
