Square Performance Wheel Sets for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

Square wheel sets include a complete set of wheels with identical dimensions for front and rear. Many OE wheels setups run square fitment as it keeps manufacturing costs lower, and offers predictable and even grip levels at all four corners. An added benefit of running a square set is reduced tire costs. Generally tires are cheaper when purchased as a complete set and are much easier to source.

18x10.5 ET22 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! 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. Spring Line Forged wheels from Apex Wheels feature: Side-milled spoke design to cut out excess material and gain wider and deeper spokes. Reinforced critical structure points to add inner lip strength and increase load rating. Weight optimized to balance strength and maintain a lighter design. Independently tested for rigorous JWL standards based on duration, impact, and total loading. High clearance barrel design for Big Brake Clearance. Paintless Knurled Beads that keeps your tire from slipping with sharp and maximized grip! Impact Socket friendly to support oversized race lugs and faster wheel changes with impact sockets. Laser-engraved specs to easily identify your wheel collection at home or in a hurry at the track! On top of all of these benefits that focus on the best user experience possible Apex Wheels goes one step further. These forged wheels are always hub centric and built for your select vehicle application, made to fit TPMS sensors and OE center caps to get a factory look with improved performance. This is a wheel you can depend on! Comes with a LIFETIME WARRANTY against material and workmanship defects and a 1 YEAR warranty on the finish of the wheels. If you are already sold on these wheels there is one last final benefit that will boost your confidence to drive these wheels to the moon and back; Apex Wheels offers 50% OFF replacement wheels no matter the damage to make sure your favorite wheel setup can go on forever!

Apex SM-10RE ​19x9.5" ET22 Square Wheel Set The SM-10RE is the forged Enduro version of our popular SM-10 design. It features our highest load rating and our strongest lip, allowing it to withstand abuse, lap after lap. Upgrade the appearance and reduce the weight of your BMW with Apex's SM-10RE wheels! Features: Fully forged 6061-T6 aluminum Stronger 2100 lb. load rating Stiffer side-milled spokes Heavy-duty Enduro Spec inner lip Capless hub design to reduce weight Massive brake clearance Unmatched replacement program Lifetime structural warranty Independently tested Retaining the same ten-spoke layout seen on the Flow Formed SM-10 and ultra light Forged SM-10RS, the all-new Forged SM-10RE gets dramatically thicker spokes, our thickest ever Enduro Spec inner lip, and a fully redesigned and reinforced outer lip. All said and done, the SM-10RE is rated at an impressive 2100 lb max load, a five-hundred pound increase over the lightweight SM-10RS. These fortifying measures have been countered with a number of unique weight-saving features as well. Just like the Sprint Line Forged Wheels, the Enduro Line SM-10RE sports deep spoke scalloping intended to machine away excess material without decreasing strength or stiffness. Going a step further, the SM-10RE does away with the center cap support, the outer barrel remains unpainted, showcasing a beautiful raw aluminum, and outer lip pocketing is present between the spokes (an Apex first!). All together, these weight-saving features result in a wheel that is shockingly light considering its impressive stiffness and load rating. The SM-10RE is significantly stronger and stiffer compared to both its Sprint Line and Flow Formed counterparts, and even more so than most competitors. The intention is for the Enduro SM-10RE to become the new de facto wheel of choice for track day enthusiasts and racers looking for a ten-spoke wheel design. For racers, track day goers and car enthusiasts in general who won’t put up with overly light wheels that bend at the sight of steep curbing, the SM-10RE is the answer!

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.

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.

RX-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 Satin Gold 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.
