Porsche 987 Spec Cayman Wheel Performance
The 987 Cayman had a wide array of wheel and tire options from the factory, none of which took full advantage of the platform. With narrow and heavy wheels there is significant room for performance advancement. Our Forged Enduro VS-5RE and SM-10RE as well as the Flow Formed SM-10 wheel offers wider and lighter alternatives for a 987 Cayman in the SPC class. Be sure to read up on exactly which 987 Cayman wheels are right for your application in our Porsche 987 Spec Cayman Wheel and Tire Fitment Guide.
History of Spec Cayman
Spec Cayman racers looking for wheels have a very particular rule set to abide by but first, what is Spec Cayman? Spec Cayman or SPC as they are badged in PCA club racing is a step up from Spec Boxster (SPB) which utilizes the 986 and the SP1 and SP3 classes with the 944. These SP1/3 and SPB are some of, if not the most popular classes seen at a typical PCA race weekend. SPC is a newer class that was finalized in fall of 2015 and intended to be a step up in performance from SPB. Where SPB runs a base trim 986 Boxster, SPC utilizes the 987.1 Cayman S with the 295hp 3.4L flat six and 6-speed manual transmission. With stringent rules on the modifications allowed and the selection of those parts helps keep the introductory cost into this field down. The same goes with engine modifications which only allow for cooling mods like an accusump and deepsump. Header modification (aftermarket headers are not allowed) as well as a race style rear section to reduce weight and open up the back of the car a bit. This is further benefited by the rear bumper opening that is allowed in SPC to further remove hot air that gets trapped in the engine bay on a stock Cayman. In terms of club racing the cost to get into Spec Cayman is pretty reasonable, especially considering the caliber of car you will end up with.
Unlike SPB, wheel selection is open as long as it is no larger/wider than 18x9 front and 18x10 rear with minimum combined wheel and tire weights of 40 lbs front and 46 lbs rear. The Spec Cayman wheels we offer are our 18x9”ET46 and 18x10”ET36 VS-5RE and SM-10RE Forged Enduro wheels and the SM-10 Flow Formed wheels. These should meet the minimum weight requirements with the spec Hankook Z214 tires installed.

VS-5RE Specifications
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.

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.

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 machined 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.
