Overview
BMW E85 E86 Z4 M Wheel Performance
The E85 and E85 Z4M was recognized as a capable platform immediately after its launch in 2006, but despite the increase in horsepower from the S54, the OE Z4 M wheels retained the same tire widths as the non-M model it was based on. This led to a tendency to understeer when pushed to the limit and makes upgrading to a wider set of lightweight performance wheels and tires one of the best performance mods an owner can do.
We created our forged wheels like the VS-5RS, EC-7RS, SM-10RS as well as the flow formed wheels such as the ARC-8, EC-7, FL-5 and SM-10s in chassis specific fitments for your Z4. Optimize your next set of wheels in our E85 & E86 Z4M Wheel & Tire Fitment Guide.
About the E85 and E86 Z4M
The E85 & E86 Z4M made its initial debut at the 2006 New York Auto Show and sold through the model years of 2006-2008. The first and only generation of BMW’s beloved Z4M was offered in two unique body styles, with the E85 as a soft top roadster, and the E86 as a hardtop coupe with a hatchback instead of the folding convertible roof. Both cars utilize the legendary 3.2 liter naturally aspirated inline-six S54 engine, pushing 330 hp and 262 lb-ft of torque at the crank. Power is sent to the rear wheels via a mechanical limited-slip differential paired with a 6-speed manual transmission, which was the only available option for both the E85 & E86 Z4M models. Furthermore, the Z4M also utilizes a hydraulic power steering rack, compared to the non-M variant’s electric power steering setup, providing additional feedback and improved overall steering feel. While the E85 has the standard steering rack from the E46 M3, the E86 uses the upgraded steering rack from the M3 CSL, which offers a quicker ratio from lock to lock.
Commonly referred to by enthusiasts as one of the most “raw and visceral” cars BMW has ever produced, the Z4M offers a ton of performance in a relatively lightweight and compact package.
The E85 & E86 Z4M was originally designed by Chris Bangle and when first unveiled, created quite a bit of controversy within the enthusiasts community. Much like the rest of the cars Bangle developed during his time at BMW, the once outlandish and striking aesthetics of the E85 & E86 Z4M have aged incredibly well as a classy and timeless design. Especially with the E86 hardtop coupe variant, the blend of the low-slung roof line paired with the rear-set cabin provides a refined yet muscular appearance that truly represents how the car feels from the driver’s seat. Filling out the massive rear fenders with a set of wide and low offset E85 & E86 Z4M wheels goes a long way in complementing the overall design aesthetics of these cars.

Which Wheels Should I Get?
Check out our Fitment Guides, the most in-depth, authoritative guides for wheel and tire fitments, tailored for your vehicle and how you drive it.
ARC-8 features
The Flow Form Advantage
Flow forming enables us to create high performance wheels without the price premium of forging. It improves the mechanical properties and grain structure of the barrel, increasing its strength and stiffness, which allows us to use less material and reduce weight. Thanks to our superior engineering, our flow formed wheels have a higher load rating than some competitors' forged wheels.
Big Brake Clearance
Big brakes often require bigger, heavier, more expensive wheels, which aren’t ideal in a performance environment. The ARC-8 accommodates many big brake kits, even with its classic deep-concave spokes. If you need more clearance, the forged ARC-8R or one of our curved spoke wheel designs has you covered.
Maximizing Concavity
We use the deepest concave face profiles we can for every application after factoring in critical clearances such as brake calipers. The ARC-8 utilizes 2 unique profiles to make this possible, with the deepest concave face delivering reduced weight and a stunningly aggressive appearance.
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
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.
32mm
Socket Diameter Clearance
Finishing Touches
The ARC-8 is finished using a multi-stage liquid paint over a powder coated base coat. This coating process leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
JWL and Beyond
All APEX Flow Formed wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.
True VIA
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. Our Flow Formed wheels have been certified, and we provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.
Additional features
Hub Centric
All ARC-8 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
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.
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.
Lifetime warranty
All APEX wheels come with a lifetime structural warranty against defects in workmanship and materials, plus a 1 year finish warranty. Exchanges are fast, easy, and hassle-free.
