981 GT4 Clubsport Wheel Performance

Being a factory race car, the 981 GT4 Clubsport wheel setup is quite dialed in. With racers generally having multiple sets of wheels already we did not want to cause chassis balance changes by adjusting the offset. For this reason we stuck with the ET41 front and ET47 rear to allow you to move between sets with minimal effects. This will be available in our Enduro line of Forged wheels, the VS-5RE. Feel free to check out our Porsche 981 Cayman GT4 Clubsport Fitment Guide for more information.

A Brief History of the 981 Cayman GT4 Clubsport

The first factory Cayman race car from Porsche motorsport. We do offer 981 GT4 clubsport specific wheels, but what differentiates the Clubsport from the street GT4 and what is similar between the two. The biggest similarity is the engine. The Naturally aspirated 3.8L from the street car remains with the same power of 385 hp. Transmission is a departure from the street car, gone is the 6-speed manual and in is a 6-speed PDK transmission. The body structure remains the same with a Porsche motorsport roll cage installed among other safety items like fire suppression and main power kill switches. There are numerous chassis changes from the street car, to start the inclusion of lightweight front suspension components of the 991 GT3 cup car. A modified version of the GT3 Cup car's strut is used on the rear of the strut based clubsports rear suspension. PFC brakes are another large upgrade for the racing focused clubsport. This included 380mm rotors front and rear with 6 piston front calipers and 4 piston rears. A 12 setting ABS system is implemented as well to cover the scope of conditions that one can expect in racing. The electronic stability control system was also tuned for the use of racing slicks. The compact nature of the PFC caliper is what allows for the use of 18” wheels on the clubsport where the street car can only use down to a 19” wheel. The 981 Cayman GT4 Clubsport wheels we offer are almost identical to the factory wheels. At 18x9”ET41 and 18x10.5”ET47 this will be a direct replacement for the factory setup without any changes to the location of the tires centerline. The same 25/64-18 and 27/68-18 tires will continue to be used along with the use of MR lug nuts.

VS-5RE Features

Our Strongest Wheels

Most motorsport wheel designs prioritize reducing weight over increasing strength, but some applications require extra strength. High grip tires and lots of downforce put extra strain on wheels. Pair that with a faster driver and regular load ratings are not enough. The VS-5RE is about 30% stronger than the RS version.

Stiffer Spokes

Wheel stiffness matters but it gets overlooked and undiscussed. The redesigned spokes of the VS-5RE are about 25% stiffer than the Sprint Line version. Stiffer spokes help reduce camber loss, which reduces outer edge tire wear and improves feel and responsiveness.

Enduro Sprint

    Toughest Inner Lip

    Introducing the Enduro spec inner lip - our strongest ever. With 50% more reinforcement, these wheels are better-protected against the harsh conditions found on and off track.


    More reinforcement

    than a standard inner lip

    Reinforced Front Lip

    We added extra material in the front lip for more durability so you can keep attacking those berms. You can easily spot the beefed up design of an Enduro lip vs. the lightweight lip on a Sprint Line wheel.

    10K Tons of Pressure

    To make our forged wheels the strongest we can, we applied as much pressure as possible using a 10,000 ton forge. 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. We designed our very own blank profiles from scratch to give us total control over the final product.

    Side-Milled Spokes

    One of the most prominent features of the VS-5RE is the extra wide and deep side-milled spokes. Any excess material that doesn’t add strength is carved out using a precision CNC ball cutter. This allows our endurance wheels to be surprisingly light for their strength. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise we believe it's essential.

    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 significantly stronger wheel with a minimal weight penalty over their RS counterparts.

    Independently Tested

    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. Our Enduro Line wheels are independently tested by ITS at their Michigan facility following JWL standards but pushed to much higher loads and much longer durations.

    Big Brake Clearance

    From day one, Apex has been on a mission to build wheels that clear big brakes. These Enduro Line wheels are the product of everything we’ve developed over the past 15+ years. We utilize 3D scans to produce vehicle-specific spoke profiles, and our wheels feature an innovative high-clearance barrel design.

    Deeper Concavity

    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 optimized for a specific application using 3D laser scans of factory and aftermarket brake kits.

    Paintless Knurled Bead

    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.

    Paintless Barrel

    To be as light as possible, and to reduce rotational inertia, we removed paint from the outer barrel. It’s only a fraction of a pound but it’s in an area that has the biggest impact on acceleration and deceleration, so it packs a bigger punch vs. the same weight savings near the center of the wheel. These small tweaks add up.

    Capless Hub Design

    We know most track day organizations ask for center caps to be removed. To further reduce weight that doesn’t directly correlate to strength, we incorporated a capless hub design on all Enduro Line wheels in our pursuit of Real Performance.

    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.


    Socket Diameter Clearance

    Outer Lip Pocketing

    A lot of areas get extra thick when the load rating is raised to 2100 lb. By CNC machining ‘pockets’ between each spoke, our Engineers were able to further reduce weight from an area that has a high impact on rotational inertia.

    Laser-Engraved Specs

    As track enthusiasts ourselves, we know how frustrating it is to locate and decipher wheel specs that have been hastily marked on a wheel or become unreadable over time. Our Enduro wheels have laser-engraved specs on the barrel, in plain sight, making them easy to find and read.

    VS-5RE Warranty

    A Wheel You Can Depend On

    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.
