One look at Spartan BMW wheels from Beyern telegraphs that these are the wheels that represent the perfect complement to the Ultimate Driving Machine. The Spartan???s eight bold U-shaped spokes strike a pose in perfect harmony with the essence of BMW, coupe, sedan, convertible or SUV. And each available finish, brilliant chrome, stunning silver or masculine matte black, adds its own distinctive rendition to the central theme. Beyond beauty, the Spartan model is a paradigm of performance. It is a one-piece wheel manufactured using an advanced technology termed rotary-forging*
* The Spartan is manufactured using a highly advanced production technique called Rotary Forging. The rim of the wheels is forged at high pressure while the wheel is spun at high speed. This alters the molecular structure and enhances the strength of the alloy. The benefit is a much lighter weight than a regular cast wheel. Most importantly, the weight saving is in the outer rim of the wheel which dramatically reduces rotational mass and enhances vehicle performance.
