Tires, Sidewalls, Things

Yeah, 15" wheels have good performance tire options because of the Miata guys. I can't remember if the FC's can fit 15" wheels over the front brakes though. Outside of actual race rubber, there aren't many 16" options left. I did the math once too. I compared the wheel of 16" RPF1's with 245/45R16 tires to 17" RPF1's with 255/40R17 tires. The overall weight was within a 1/2 lb or so (17" heavier) and the 16" combination puts the rotating weight slightly closer to the hub.
