The G82 M4 coupe and G83 M4 convertible are the two-door counterparts to the G80 M3 sedan -- the same S58 twin-turbo inline-six making 503 horsepower in Competition trim, the same 5x112 bolt pattern that marked a generational break from every M car before it, and the same aggressive offset that fills the wide box-flared arches. The factory wheels are cast 18-inch base units, forged 19-inch mid-tier, and forged 20-inch Competition Package wheels. A modern forged monoblock can beat all three on weight while matching or exceeding the factory offset and brake clearance.
The G82 and G83 share wheel fitment with the G80 M3. The 5x112 bolt pattern means these wheels are not backward-compatible with the F8X generation -- this is a clean-sheet fitment for the G-chassis M cars. The offset accounts for the M-specific front axle geometry, the large six-piston front brake calipers, and the fender clearance at full compression. The G83 convertible uses additional underbody bracing that does not affect wheel fitment, but the staggered tire sizing and factory DSC calibration are designed around the same wheel widths as the coupe. Our offset is measured on a real G82 M4 chassis through the full steering range. The wheels sit flush without spacers.
Forged 6061-T6 aluminum monoblock. Available in 19-inch for maximum sidewall compliance on real-world roads, or 20-inch for the factory Competition stance. Custom spoke design. Brushed, polished, satin black, gloss gunmetal, bronze, gold, frozen silver, or custom color. The G8X M4 is heavier than the F82 it replaced, and reducing unsprung rotating mass from each corner is the most direct way to sharpen the steering response and improve the ride quality. Machined or laser-etched logo. Private-label packaging. Your Spec. Our Factory.
