BMW E89 Z4 Wheel Performance
Despite the switch to more powerful turbocharged powertrains, the second generation E89 Z4 wheel fitments lacked width both for tire size and wheel size. Narrower 225 section front tires also made the default handling characteristic of the chassis understeer, despite the focus on a RWD layout. A set of lightweight chassis specific wheels is key to unlocking the performance of the E89 chassis.
We created forged wheels like the EC-7RS, SM-10RS, and VS-5RS to complement our flow formed wheels like the ARC-8, EC-7, FL-5 and SM-10s, giving enthusiasts multiple options at competitive price points. Learn more about which setup via our E89 Z4 Wheel and Tire Fitment Guide.
About the E89 Z4
Launched in 2009, The E89 Z4 represented a shift in overall philosophy for BMW’s sports car platform. Gone were the multiple chassis with fixed hardtops and convertible roofs. This traditional split was instead replaced with a single model that used a folding metal roof providing in essence, the security of a hardtop with the open-air driving experience of a convertible. While this provided more comfort and security relative to a traditional soft top convertible, the lack of true hardtop led to a heavier overall platform.
Unlike the Z3 and Z4 generations before it, the E89 Z4 did not get a dedicated M model. Turbocharging came to the Z4 platform with the E89 generation with a wide range of 4 cylinder and 6 cylinder models. Lower tier models began with the naturally aspirated N52 and N53 engines but eventually switched over to N20 4 cylinder models. The N54 powered the top of the range sDrive35i and sDrive35is models. A 6 speed manual and several automatic transmission options were available, along with a unique dual clutch as the only transmission available on the sDrive35is models. Turbocharged models benefit immensely from an aftermarket E89 Z4 wheel fitment to aid in putting down all that torque.

REAL DRIVERS NEED REAL PERFORMANCE.
Not all claims of performance are backed up by facts—and it's a big problem. Don't get sold fashion when you want function.
VS-5RS features
10K Tons of Pressure
Our new forgings weigh as much as 120 pounds before machining. To form such a thick blank we require special equipment capable of 10,000 metric tons of pressure. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.
True Motorsport Blanks
Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. We designed our very own blank profiles from scratch to give us total control over the final product.
Side-Milled Spokes
To be as light as possible the VS-5RS features extra-deep, side-milled spokes. Any excess material that doesn’t add strength is machined out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise we believe it's essential.
A Stronger Lightweight Wheel
Our forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we machined out as much material as possible, then we purposefully added one pound back to reinforce critical areas, creating a stronger inner lip and a higher load rating.² What’s the point of a lightweight wheel if it’s fragile?

Weight Optimized
We conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn’t improve strength. The result is a wheel that is exceptionally light without the strength compromises found on typical lightweight wheels.²

Independently Tested
We don't rely solely on computer simulations or unverifiable in-house testing. We believe independent testing is critical to protect consumers in this unregulated industry. We chose STL, an independent lab in Ohio, to test our Sprint™ wheels far above JWL standards, including increases in testing duration, impact drop height, and total load.
Tougher Inner Lip
Introducing the Sprint™ spec inner lip, with a unique channel profile that makes it even stronger than our previous designs. So even though our Sprint™ wheels are pounds lighter than comparable flow formed wheels, the inner lip is stronger.

Big Brake Clearance
From day one, APEX has been on a mission to build wheels that clear big brakes. Our new forged wheels are the product of everything we’ve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles.
Deeper Concavity
Our new forgings were redesigned to create extra deep, concave spoke profiles. Their new shape allows us to make any profile, from flat to deep and everything in between. Each one is optimized for a specific application using 3D laser scans of factory and aftermarket brake kits.
Paintless Knurled Bead
Whether it's a day at the track or months of street driving, repeated hard braking and acceleration can make a tire slip along the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. Our forged line features unpainted knurled beads that stay sharp and maximize grip.
Built for Impact Sockets
Track wheels need track tools. Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.

Laser-Engraved Specs
As track enthusiasts ourselves, we know how frustrating it is to try to locate and decipher wheel specs that have been hastily hammered into the rim or become unreadable over time. With our new Sprint™ wheels, we chose to invest a little extra and laser-engrave the specs on the barrel, in plain sight, making them easy to find and read. (You’re welcome.)
Additional features
Hub Centric
All VS-5RS wheels are purpose built for select vehicle applications. Very few applications require centering rings.
Center Caps
All APEX wheels come with our gloss black cap included that is interchangeable with the OE cap. We also offer additional colors for select fitments.
Wheel Hardware
APEX wheels can be used with all OEM mounting hardware, proper aftermarket hardware and most wheel spacers. Wheel locks and stud conversion kits also work perfectly.
TPMS
All APEX wheels accept OEM and aftermarket Tire Pressure Monitoring Sensors and standard fit valve stems. If you don’t have sensors, then select from our metal stems available in multiple finishes.
Accessories
A Wheel You Can Depend On
Accidental damage replacement
Curb rash or pothole damage on the street? Make an oopsie at the track? We’ve all been there. APEX is proud to offer 50% off replacement wheels, no matter the damage.
