These chrome wheels do make all the difference in how the Edge looks, they are just a pain in every way.
I doubt that the plastic chrome makes them lighter, there is still a big ol' rim under it.
For $800.00 I would buy a new set of real chrome rims. If I do not buy a new Edge next year I am prob going to replace the plastic rims, mine are showing corrosion already. A long Chicago winter will prob make a mess of them.
