I am looking into buying new rims (once I have the money) and would like something around the size of 18" x 9". I currently have the stock GT wheels(16"). If I get 18" x 9" is there anything else I would need to consider? Will those wheels fit with no problems or are there extra parts or considerations I would need to make? Thanks for the responses. I have appreciated the direct and helpful responses people have given since I've joined.
