I've been considering this for the past few weeks and have been trying to do some research. Unfortunately I only have pictures to go on and from the side angle it doesn't look like the rear will be much lower then the sides since the rear angles up sharply.
Anyone with an HFP kit willing to find out how much lower the rear sits on the stock rear bumper?
If no takers then I will proceed with ordering it, but not for a few more weeks. I'm one of many who have bumper damage.
