The F32 4 Series coupe, F33 convertible, and F36 Gran Coupe are BMW's style-focused midsize coupes -- built on the same platform as the F30 3 Series with a lower roof line, wider stance, and more aggressive proportions. The range spans the 428i and 430i with turbocharged four-cylinders to the 435i and 440i with the legendary N55 and B58 turbocharged inline-sixes. The 4 Series uses a 5x120 bolt pattern with a 72.6-millimeter hub bore, sharing the architecture with the 3 Series but with a wider front track that changes the offset requirements. The factory wheels were 17-inch through 19-inch units, with 20-inch on some M Sport and competition configurations. A forged monoblock upgrade reduces unsprung mass and sharpens the response of the wider, lower 4 Series chassis.
The three body styles share identical wheel fitment. The wider front track of the 4 Series compared to the 3 Series means the front offset differs from the F30, and the offset must clear the larger M Sport brake calipers on the 435i and 440i while filling the wider, flatter arches that define the 4 Series silhouette. Our offset is measured on a real F32 440i chassis through the full steering and suspension range, with the M Sport adaptive suspension at its lowest setting. Direct hub-centric fitment with the correct 72.6-millimeter center bore. No spacers. No centering rings.
Forged 6061-T6 aluminum monoblock. Available in 18-inch for a sport profile, 19-inch for the standard M Sport stance, or 20-inch for an aggressive upgrade that fills the 4 Series arches completely. Custom spoke design -- a deep-concave split-spoke, a mesh, or a modern multi-spoke. Brushed, polished, hyper silver, satin black, gloss gunmetal, bronze, gold, or custom color. The B58-powered 440i is one of the most capable coupes of its generation, and forged wheels complement its tuning potential by improving the chassis response. Machined or laser-etched logo.
