Wow, I like that man! My rear bumper has got a good size dent in it I was looking into getting new front/rear bumpers, these ones are not too expensive.
I think its 5-6 inches also. Get the coilovers and do it right the first time, spend the extra dollar to get it done right. The suspension, especially if your planning a big lift needs all the support you can give it. Can't wait to see some pics.
