The Z4 M Roadster and Z4 M Coupe are the last naturally aspirated M cars built on a dedicated two-seat platform, powered by the S54 3.2-liter inline-six from the E46 M3. The E85 Roadster and E86 Coupe share the S54's 338 horsepower, its 8,000 RPM redline, and its six individual throttle bodies -- and they carry all of that performance on a set of factory 18-inch cast or forged Style 224M wheels. A modern forged monoblock wheel set shaves 3 to 4 kilograms per corner from a car that weighs significantly less than the M3 it borrowed its engine from.
The Z4 M's wheel fitment is specific to this chassis. The 5x120 bolt pattern is shared with the E46 M3, but the offset is different -- the Z4 platform uses a unique front and rear track width that differs from the E46, and the Z4 M's wider arches require offset that fills the wheel wells without rubbing the fender lips under the stiff suspension travel of the M-specific dampers and springs. The rear offset is particularly critical because the Z4 M's semi-trailing arm rear suspension changes camber significantly under compression, causing the top of the wheel to tuck inward and the bottom to push outward. Our offset is measured on a real E86 Z4 M Coupe chassis through the full suspension travel. The wheels clear the large floating brake rotors and the M-specific calipers. No spacers required.
Forged 6061-T6 aluminum monoblock. Available in 18-inch for a period-correct profile, or 19-inch for a more contemporary stance that fills the Z4's long hood proportions more aggressively. Custom spoke design -- a deep-concave split-spoke that echoes the factory Style 224M look, a modern multi-spoke, or a full custom profile. Brushed, polished, hyper silver, shadow chrome, satin black, gloss gunmetal, bronze, or custom color. The Z4 M Coupe is one of the most collectible modern M cars, and the Roadster is not far behind. Their wheels should match the rarity. Machined or laser-etched logo. Private-label packaging. Your Spec. Our Factory.
