i wouldnt get fb sides. if u plan on lowering the sides will take a beating

 

Stock body with a drop and wheels with a good fit and wheel offset is all you need for the exterior.. G's are so sexy with the stock sport body.. I had a lip and sideskirts and couldn't wait to get them off my car to go back to the stock bodyparts, not to mention oem fitment and quality can't be beat!!

 

CS rear and impul sides wont go well with oem 19s. Both will make your rear wheels look really small.
You will need more aggressive 20s to pull off a kit like that.

 

I wouldn't get fg sides cause I've seen many people having fitment problems. Like its not even doable.
