APEX ARC-8 18" Staggered Wheel Set -- 18x8.5" / 18x9.5"

This set of 8.5" and 9.5" ARC-8 wheels is an easy staggered fitment for the E46 M3 and Z4M models. These are a direct fit with no spacers or fender rolling required. We use an 8.5" ET38 on the front and a 9.5" ET22 on the rear. These are only slightly wider than the stock sizes. The rear wheels have a deeper concave face than the fronts, emphasizing the RWD chassis and adding some muscularity to the stance.

APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance. The spokes and barrel have been designed to allow generous clearance for big brakes. In other words, these wheels are very impressively engineered and look great too! The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. Don't let the price fool you - these wheels are high quality, high strength, and in high demand.

Note: careful consideration of wheel width, offset and tire sizing must be observed when choosing and installing larger wheels. Adding larger wheels may lead to rubbing on suspension components or bodywork. Wheel spacers, new alignment settings, inside fender modifications, or other adjustments may be required.

H&R Wheel Spacers for BMW

Enhance your BMW's performance and aesthetics with wheel spacers from H&R. These spacers offer a multitude of benefits, providing you with an all-around upgrade for your vehicle. By installing wheel spacers on your hub, you can accommodate larger brakes, thanks to the additional clearance they provide behind the wheel. Experience improved handling and grip in corners, along with the ability to run a more aggressive wheel fitment for that desired look. Made from a proprietary aluminum/magnesium alloy, H&R spacers are both incredibly strong and lightweight, weighing up to 70% less than comparable steel products. Hub-centric design ensures the highest level of accuracy, while the spacers are 100% made in Germany under ISO 9001 Quality Assurance standards, meeting the strict safety criteria of the German TUV.

BBS Wheels combine decades of race proven quality and German engineering with stunning good looks. Utilizing the most cutting-edge manufacturing technologies based on a foundation of constant innovation continues to propel BBS into the future.

CI-R wheels consist of a pressure cast wheel surface and a flow formed rim structure.  Combining these two fabrication techniques yields a wheel that is extremely strong while remaining lightweight.

Using FEM analysis the engineers at BBS are able to precisely measure and optimize wheel properties before this process even begins. Once the forging process is complete, the meticulous finish work begins.
Back-milling is a process used to optimize the ratio between weight and stability. Using advanced computer analysis and a special CNC milling process the lateral parts that hold the wheel spokes, and are not relevant for stability, are removed. Extensive real-world simulation is used at this point to further ensure that no strength or stability has been lost.
Finally, BBS pays special attention in machining the undercut or back side of the wheel. To machine the undercut, all areas on the inner side of the wheel and the star hub that correspond to weight optimization are processed with special turning or milling tools and excess material is removed to reduce the rotating wheel mass. Special attention is hereby given to the optimization of the inner sides of the spokes and the bolt circle. With the application of these methods, BBS is able to produce more complex forms with increased stability and less material input.
These wheels come in a Satin Black and BBS ensures that their paint quality exceeds OE manufacturer specifications for durability and longevity. A final protective clear coat layer ensures that these wheels will be easy to clean and look amazing for years to come.

Please Note: Aggressive fitment, may require fender rolling or pulling.
