Designed for the series regulations, our Spec E46 wheels are built from the ground up to give racers a competitive advantage. Our forged wheels like the VS-5RS are built to the limit of the rules, saving every ounce of weight while featuring a stronger inner lip. The flow formed ARC-8 wheels on the other hand offer racers an affordable and versatile wheel, perfect for building a large multi-set inventory or sets of rain tires. Be sure to review our Spec E46 Wheel & Tire Fitment Guide to ensure you stay class compliant.
Spec E46 is a competitive racing class focused on a single model of E46 BMW 3 series. As one of the premiere BMW-focused wheel brands, Apex has long been a mainstay of Spec E46 wheels, with fitments being designed specifically for this segment. The class is based around the sedan or coupe 330i or 330ci, one of the upper range of 6 cylinder E46 non-M3 models just below the ZHP. These cars provide an affordable and nimble platform focused on a relatively lightweight chassis with solid handling. Grids are typically a tightly packed and highly competitive field depending on region, with even racing and driver development being the main focus.
All 330i models are powered by the 3-liter M54 engine. This is a tried and true engine that BMW used in a variety of models throughout the years, which is also readily available at junkyards around the country, should the worst come to pass. AWD (xi) models are not permitted and 5 or 6 speed manual transmissions are mandated. Suspension requires the use of MCS non-remote reservoir single-adjustable dampers with Spec Hyperco springs. Camber plates can and should be used.
As mandated by the series, Spec legal E46 wheels must be no more than 9” wide, 17” in diameter and with an effective offset of 27 front and 38 rear. Apex 17x9 wheels are used with a 42 offset and 12mm front spacers for suspension clearance. Our ARC-8 model was the original wheel often campaigned in this class and is a great option for racers on a budget that need multiple wheelsets. Our VS-5RS wheel has been designed specifically for this class with a per-wheel weight brought right down to the 16.2 lb class limit. These wheels are typically wrapped in the class-mandated Toyo proxes RR slicks in 255/40-17 sizing. Toyo RA1 235/30-17s can also be used on the same wheels for sessions with rain.
For anyone considering building or purchasing a Spec E46, the Official Spec E46 Rule Book is a must-read for obvious reasons.

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.
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.
To be as light as possible the VS-5RS features extra-deep, side-milled spokes. Any excess material that doesn’t add strength is carved 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.
Our forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we carved 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?
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
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.
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.

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.
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.
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.
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.

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.)
All VS-5RS wheels are purpose built for select vehicle applications. Very few applications require centering rings.
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.
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.
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.
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.
