So thats why i am willing to pay almost 500 dollor to order a costum made wheel adaptors to properly fit the wheels on my car, but my only problem is the offset that i still dont know much about it, so can i install them without doing any modification to the car? I can also deside on the thickness of the adaptor with minimum of 25 mm.
