Too small for the mod?

I sold mine for 700 with tires and they had curb rash. I am not putting the lip on my GT3 bumper because it came with a "boomerang". That should be a lot of help. About clearence... Imagine your stock bumper... but an inch lower on the sides, and flush with the bottom of the car (your underbody plates). This bumper does not curve up, but stays flat with the bottom of the car, and is lower on the sides is what im syaing... basically.
