18x10" ET40 APEX EC-7 Mustang Wheel

Fit Matters

The right solution for every application

The EC-7 wheel includes details specifically implemented to enhance the Mustang owners' track day and street performance experience. An optimized car setup begins with the right wheel and tire fitment, and without model-specific attention, maximum performance is compromised. These wheels were developed exclusively for S197 and S550 chassis, and will work in either square or staggered applications. Most fitments are direct bolt-on solutions, however aggressive square fitments utilizing the 18x11” EC-7 wheels will require spacers on the front axle for proper inner strut clearance. This not a compromised fitment, it is the only way to outfit an S197 or S550 chassis with the highly desirable true-rotatable 11” square fitment.

Simply put, our wheel was designed for long-term durability without sacrificing performance and fit, while also adhering to APEX’s mission of maximizing value. Corner carving & track enthusiasts: this is your wheel.

Face Profile

One design, many levels of beauty

The EC-7 wheel is manufactured in three increasingly-concave face profiles; The shallowest face provides increased caliper clearance on narrow applications, while the deepest concave face reduces weight and creates a stunningly aggressive appearance on low offset and wide-width applications. This Mustang application utilizes our medium profile for the best balance between caliper clearance, concavity, and weight.

Spokes

More than just a pretty face

The curved spokes of the EC-7 serve many purposes, both in terms of form and function. The split "Y" spokes were carefully evaluated from every aspect to ensure light weight and remarkable strength. Their curved design increases brake calipers in almost every application, allowing the EC-7 to fit where the ARC-8 design simply cannot. The unique curvature of each face profile reduces center pad material as they are optimally selected for each unique width and offset. The lack of a deep front lip and spokes that connect directly to the barrel's lip, producing a rigid wheel with even load distribution.

Brake Clearance - Spokes

Spokes that work for you

If the spokes of a wheel don't clear your brake calipers, then the wheel can’t be used at all. We made sure these wheels offer ample brake clearance, effectively clearing a variety of aftermarket BBK’s as well as popular factory BBK’s like the S197 14” and 15” GT500 Brembo BBK’s, as well as the S550 Performance Package Brembo BBK. The S550 GT350 would require our 19” EC-7.

Brake Clearance - Barrel

A lot of room in a tight space

Designing a wheel with spokes that clear a Big Brake Kit, is only half of the battle. The inside of the barrel needs to be large enough to physically fit large calipers and rotors. Be warned— not all wheels are made equal. The barrel of the EC-7 wheel offers unmatched caliper clearance because wheels shouldn’t limit your choice of aftermarket brake kits, and brake kits shouldn’t force you to run oversized wheels. We 2D modeled most Big Brake Kits available in Solidworks and tweaked the wheel design of the EC-7 prior to production in order to fit as many kits as possible.

Hub Center

Form follows function

Race wheels can't just be light, they need to function in a high performance environment. Unlike the narrow lug recesses of most other wheels, the EC-7 wheel features bored-out lug recesses that easily accommodate over-sized race lugs and beefy impact sockets. This allows for quick and easy wheel changes and prevents chips and scratches from tools.

Hub Centric

No rings or adapters here

All APEX EC-7 wheels are purpose built for select vehicle applications, and centering rings are never required for any Mustang S197 or S550 application. All 5x114.3mm bolt pattern wheels feature a direct-fit, 70.5mm center bore.

Center Cap

A factory fit and finish

We don't reuse one cap design for all of our wheels. Every EC-7 wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM Ford center caps for a clean factory look. The EC-7 wheels will ship with our Gloss Black center cap that mimics the size and shape of a Ford factory center cap.

Wheel Hardware

Original or Aftermarket, it all works

The EC-7 wheel can be used with all OEM and aftermarket mounting hardware with a 60° tapered seat. Lug bolts, wheel locks, and stud conversion kits all work perfectly. The EC-7 wheel also accepts wheel spacers without issue. The shallow rear chamfer allows the wheel to remain hub centric even when 5mm flat spacers are used. The chamfer is deep enough to clear the chamfered lip found on some aftermarket spacers that would typically cause improper seating of the wheel and, therefore, wheel vibration.

TPMS Sensors

They all fit

TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. The attention to OEM compatibility on the EC-7 wheel doesn't end with center caps. All APEX wheels accept OEM and aftermarket equivalent TPMS sensors, and any standard sized metal or rubber valve stem.

Flow Forming

Benefits of forging, without the pain

These APEX wheels are produced using a manufacturing process known as flow forming. This process significantly reduces weight in the barrel, which has the greatest impact on rotational mass. During the manufacturing process, rollers apply high pressure to the inner barrel, compressing the aluminum into its final shape. This effectively eliminates porosity and aligns the grain structure of the metal, which increases tensile strength. The end result is a lightweight and extremely strong barrel that equals that of a traditional forged wheel at a fraction of the cost.

Weight & Strength Optimization

It’s all in the details

Various design features were implemented to ensure that the EC-7 wheel design was light, but had even more strength to handle the abuses experienced in endurance racing. We began with a beefy, multi-spoke, one-piece design. We added reliefs in the mounting pad to remove weight between lug holes, where we could safely save weight. The design was then run through Finite Element Analysis (FEA) to further optimize the spoke and barrel design. The result is a lightweight wheel with extra strength in all the right places. Use the EC-7 with confidence. It’s over built for both street and track.
