I would love to put a set of black saleen wheels on my 05 grand prix. I just read the (Does anyone have these wheels) thread and have a few questions. According to the thread and my own searches the +36mm offset 18x9 are no longer made. So, I can purchase the +30mm offset wheels anywhere. By what i am reading i will have to (roll the fenders) to make them fit correctly. Is this correct? If so can someone explain in a little detail what fender rolling is(possibly with before and after pics) and what tools are needed. I have done some basic body work before but unsure about this mod. What tires are going to fit correctly also since many sizes fit these wheels. I do not want to worry about rubbing or anything else. I apologize if there are to many questions all in 1 thread. Thanks for the input.
