The RPF1 is the lightest wheel you can bolt to a Civic, an S2000, a BRZ or a Miata for the money, and the reason is plain: six thin spokes, a MAT rolled rim and no extra material anywhere. It runs 14 through 18 inch in widths from 7 to 10.5, and Enkei publishes the weight of every size so you can compare it against the wheel you are taking off.
The 17x9 +35 and 18x9.5 +38 sizes are the ones that made the wheel, because they put a 255 or 265 tire on a Civic Si, an FR-S or a WRX without a fender roll. Black chrome, gloss black, gold and matte black are the finishes. Silver is the classic one on a track car.
