Carbon fiber seats and ceramic brakes were the only two options not selected with the dealership. The brakes I could do without but the seats have been really bothering me. Only problem is getting the seats after the fact is entirely too expensive. With that said, this is a nice alternative I will be adding until I can track down a set of seats at a reasonable price.
