that they way the kit is, especially if it is from Ground Designs. I had the same kit too. It is suppose to sit higher, because it is was lower, then it would really scratch everywhere.
Although you could call me a hypocrit since I didn't like that look, and got the R33 skyline front which hangs much lower. perfect match with the R33 sides.
Here's a pic btw:
