if a business is making a profit they dont "willingly" go out of business. So to make this easy, if you sell body kits and the fit like shit, well ppl dont buy them. If ppl dont buy your kits you dont make money, so you go out of business.
My kit that I bought was a replica, bought it for 500, it fit like a square peg does in a round hole. after dumping 2500 into body work it now fits better then a authentic kit ever could. So that 500 kit really turned into a 3000 kit
Lesson is, dont be fooled by the price of the kit. If its cheep plan on spending at least 3x the selling price to get it to look good.
Now as for the rims... do bears shit in the woods... hell Id buy a set
