► APEX | FL-5 Lightweight Track Wheels



Introducing the all-new APEX FL-5

The FL-5 is the only APEX design that that takes advantage of Dual Flow Forming plus our newest “I” beam machining technique. Still a one-piece wheel, the Dual Flow Forming technology strengthens both inner and outer barrels while maximizing front lip depth for each unique width and offset. Overall strength has been increased over previous designs which ensure durability in both street and track environments. The advanced “I" beam spoke milling further reduces weight and adds a visual feature typically only found on the most expensive race wheels available on the market today.

Visit our website to order

The New Stuff



1. “I-Beam” Spokes
This is the most significant new feature we’ve added. Weight is reduced by CNC machining material out from the sides of each spoke. It’s expensive and avoided by almost every manufacturer, but we’ve made it affordable through volume production.

2. Factory Support
Like all our APEX wheels, The FL-5 supports all OEM hardware like OEM Roundel center caps, wheel lugs, valve stems, and TPMS sensors. No centering rings are needed either.

3. Beefier Lips
By saving weight elsewhere, we’ve added extra material where it counts. We beefed up the barrel’s inner lip to better handle the abuse from the street and track.

4. Dual Flow-Formed
The FL-5 is our only design with a front lip, and it’s also our only wheel that features the use of rotary forging for both the front and rear barrels. We did this because we needed to produce the strongest front lip possible, and we can optimize the depth of the front lip for every unique width and offset when we use this more advanced production method.

Designed for the Performance Enthusiast

Light-weight
Flow-forming allows for a significant reduction in rotational mass by reducing barrel weight. This manufacturing technique allows our wheels to be almost as light as a traditional forged wheel, but without the significant increase in price.

Strength
Track duty requires a wheel that can handle the punishment of high lateral G’s, hitting berms, and every once in a while, a small off track excursion. Spoke and barrel design are a major factor in wheel strength. The flow-forming technique uses high pressure disks/rollers to roll the wheel’s barrel into its final shape. This gives the barrel the same strength properties as a forged wheel, since monoblock wheels go through a similar step to form their barrels. We design our spoke dimensions to help evenly distribute loads from the barrel to the center of the wheel. The lack of a front lip, and spokes directly connecting to the edge of the wheel, also add increased strength to the outer lip of the wheel.

Chassis-Specific Fitments
Stretched rubber, narrow tires, and fender rubbing are not elements to look for in a competitive wheel/tire setup. All of our wheels were designed with offsets that allow for proper fitment of extreme summer, and r-compound tires without the need for spacers or fender rolling. This means keeping the tire under the fender, and away from suspension components. Track oriented wheel widths are also important as they provide proper sidewall support under hard cornering. Too much rubber for a wheel results in excessive sidewall deflection, which translates into sloppy and delayed turning response.

Multiple Fitment Options
Most BMWs come with a staggered setup from the factory. Some choose to keep their car this way, while others like to switch out for an easy-to-rotate, square/neutral setup. This is generally based on driver’s preference and consideration of tire costs. Most BMW chassis benefit from being able to fit both square and staggered setups with relative ease. 9.5” or 10”-wide square setups are great for budget minded enthusiasts who want to extend their tires life by rotating between events, in addition to preferring the feel of a square setup. Square setups are popular on all models for track use due to the significant increase in front grip and turn-in response. Some owners comment that due to the extra power of their cars, a square setup will lean towards oversteer. For those who prefer more rubber in the rear, a staggered setup is the way to go. Wheels up to 11" wide are available for rear fitment. These can be combined with 9.5” or 10” fronts for a bolt-on spacer-free staggered setup.

BBK Clearance
Many owners install Big Brake kits on their cars. Having a smaller-diameter wheel that can clear large calipers is a must. Due to the low-offset nature of many BMWs, there are no clearance issues with the concave spokes. Barrel clearance was increased during the design phase to accommodate both StopTech and Brembo's 380mm kit.


The APEX Standard



1. FEA Optimization
We took more time than ever before on this step, revising and iterating our design to reduce weight as much as possible. After countless iterations we removed material from the sides of the spokes in a way that allowed us to increase strength over our previous designs.

2. Always Flow Formed
All APEX wheels feature Flow-Formed construction that utilizes rotary forging to produce a strong and lightweight barrel. The FL-5 is no exception.

3. True JWL & VIA Certification
Strength needs to be certified. Our wheels were not simply FEA tested in a computer simulation, or in-house tested to an unregulated standard. We conduct real-world crush-testing and all of our wheels conform to Japan’s JWL standard, as well as being 3rd-party tested by the VIA. All of our wheels carry a 690KG load rating.

Love the new wheel. If I still had my car, I'd sell my ARC-8 and pick up these for sure. Can't wait to see some pics of BMW's sporting these.

Agreed, can't wait to really see these on some cars.
The Photoshop images just don't do them justice.

These wheels have the same clearances that the ARC-8's have right?
So that they clear BBK's?

Our new wheels have even better brake clearance than our ARC-8's

We do not have any set ETA's just yet for more fitments in Satin Black, but it may be something we offer in the future. Our initial release only included the most popular fitments and finishes, but we will be sure to "fill in the gaps" with future production.

Love the FL-5. Looking for a set of wheels for my 2006 E91! Really need to keep the weight down on this Xi wagon. Would the 18x8.5's work with 245/40 tires?

Sport suspension on the wagon. I'm thinking of the Anthracite with the medium lip.

Thank you for the kind words. Our FL-5 wheels would look great on your E91 We recommend pairing 235/40-18 tires with out 18x8.5 ET35 wheels. 245/40-18 would fit, but they do sit a bit tall. Another fitment that you could run would be our 18x9 ET30 with 255/35-18 tires all around. This will be a direct fit on your car and look great

Any chance of getting that in the hyper black? It looks a little brighter than the Anthracite. I think the Monaco blue tends to hide really dark wheels.

We appreciate the feedback! We do not have any plans to produce these wheels in a Hyper Black finish at this time, but it may be something we consider in the future!

Matt, I am about to pull the trigger. Will the 18x9 with 255/35-18 require any mods to work? Would a camber adjustment be necessary or recommended?
I will track this car for fun.

That's great to hear! The 18x9" ET30 wheels paired with 255/35-18 tires is a very good performing setup, maximizing wheel and tire width under the front fenders without having to dial in gobs of negative camber. It typically is a direct fit on stock suspension and some coilovers. With that said, tolerances are tight towards the suspension, and when using KW coilovers (known for robbing a bit of inner clearance in comparison to other suspension designs) you will likely need to incorporate spacers to ensure proper clearances and then additional camber dialed in.
