APEX Wheels 2015-2022 Ford Mustang S550 18×10″ ET40 Anthracite VS-5RS Forged Wheel

Your Fastest Lap Is Calling

As part of APEX’s forged Sprint™ line, the VS-5RS was built to be extremely light while still offering a meaningful strength increase over the flow-formed wheels. Engineered for drivers looking to shed as much weight as possible to improve lap times.

10K tons of pressure

APEX’s 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. APEX designed their very own blank profiles from scratch which gives them total control over the final product, resulting in exceptionally deep spokes and stronger designs.

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 carved out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance, without compromise, APEX believes it’s essential.

A stronger lightweight wheel

APEX’s forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, they carved out as much material as possible, then they 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

APEX 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.

Independently tested

APEX doesn’t rely solely on computer simulations or unverifiable in-house testing. They believe independent testing is critical to protect consumers in this unregulated industry. APEX chose STL, an independent lab in Ohio, to test their 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 APEX’s previous designs. So even though the 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. APEX’s new forged wheels are the product of everything they’ve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles.

Deeper concavity

APEX’s new forgings were redesigned to create extra deep, a 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 beads

Whether it’s a day at the track or months of street driving, repeated hard braking and acceleration can make a tire slip along with the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. APEX’s 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 oversized 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 APEX’s 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.)
