Other than the laws of physics creating various outcomes in damage....like how fast the guy hits you...how far he skidded before hitting you...weight of the vehicle hitting you...ride height..etc....etc...

I was impressed with Joe's use of the rhino step plug in bumper bar for the rear hitch. (the VX owner who does the calenders)

I have the D'Lan hitch (that was how it was spelled when I bought it) as does he and his experience was he was rear-ended I believe twice and only had to throw away the Rhino bumper bar and replace it for like $100. I know he made mention of a Mustang GT slamming into his rear and the only damage to his VX was the aforementioned Rhino bar. So I bought one..plus I like the look as it complements the Safari bar I have on the front-end and the rockslider bars on the sides.

I know it isn't a cure-all for rear-end collisions but I thought it can only help after reading Joe's posts.
