Hi, I am looking for new wheels for my 2is, 2011. I know nothing about wheels. After I did some research, still hard to understand the correct sizes and fit. Right now I believe I have OEM size wheels. I am looking for wider wheels, bigger wheels, as wide as big as possible, without hurting performance and car balance. There are so many numbers involved which give me a headache. I am getting new calipers, break pads, rims and tires.

Please help out the rookie here. Thank you!
