Are you talking about the sport package fender flares? They're available from the parts counter at the dealer, but, you'll have to have them painted to match your vehicle.

I don't mean the fender flares....
I believe there are some products, like insersts, can be put on before the rims, which extended the length of the axle, but I don't know are those kind of stuff is safe or not. That's why I wanted to know whether any of you guys have those things on, or know anything about.

I wouldn't recommend wheel spacers on a ML, but then that's a personal choice, I suppose. I can't imagine any benefit other than looks, which is subjective, obviously.
