Your car will be a bit slower but it's totaly up to you whether or not you want looks or speed. BTW It isn't "R rated" it means rim size. EVERY tire has the R in it. The Speed rating is followed by the Rim size or sometimes the tire aspect ratio. I remember walking into a tire shop and looking like a complete moron when I asked for an r rated tire:).
