Competition Package (ZCP) cars came on 19-inch 163M cross-spokes: 19x8 ET47 front, 19x9.5 ET27 rear, 225/40R19 & 255/35R19. Base cars: 18x8 ET47 / 18x9 ET26 on 225/45R18 & 255/40R18.
Brakes are the same size on ZCP and base (325mm front), so wheel choice is identical — only the factory tire size differs.
The enthusiast standard is 18x9.5 ET35 square on 265/35-18 (min -1.5 deg front camber). Tire Rack stocks 19-inch only for this car today.
