So I'm finally going to get some new shoes. At first I was set on the 57S Pro, but then the GP came into the picture. They both look very similar with 7 spokes. I know that the GP weighs 17.75lbs(King Motorsports) or 16.5 (College Hill Honda) each (18x7.5), but there's not a lot of info on the 57S. Does anyone have any info to help me make a decision? Or does it even matter which I choose since they are so similar. This may be a stupid thread, but I'm a little stuck in the middle.
