The Enduro Line SM-10RE is our most recent iteration of our ten spoke wheel design, reworked from the ground up with a major emphasis on strength. Because most enthusiasts need more strength and not less, we created the SM-10RE to give buyers the option to choose whats best for their needs.
Retaining the same ten spoke layout seen on the Flow Formed SM-10 and ultra light Forged SM-10RS, the all new Forged SM-10RE gets dramatically thicker spokes, our thickest ever Enduro Spec inner lip, and a fully redesigned and reinforced outer lip. All said and done, the SM-10RE is rated at an impressive 2100 lb max load, a five-hundred pound increase over the lightweight SM-10RS. These fortifying measures have been countered with a number of unique weight saving features as well. Just like the Sprint Line Forged Wheels, the Enduro Line SM-10RE sports deep spoke scalloping intended to carve away excess material without decreasing strength or stiffness. Going a step further, the SM-10RE does away with the center cap support, the outer barrel remains unpainted showcasing a beautiful raw aluminum, and outer lip pocketing is present between the spokes (an Apex first!). All together these weight saving features result in a wheel that is shockingly light considering its impressive stiffness and load rating.
The SM-10RE is significantly stronger and stiffer compared to both its Sprint Line and Flow Formed counterpart, and even more so than most competitors. The intention is for the Enduro SM-10RE to become the new de-facto wheel of choice for track day enthusiasts and racers looking for a ten spoke wheel design.
For racers, track day goers and car enthusiasts in general who wont put up with overly light wheels that bend at the sight of steep curbing, the SM-10RE is the answer!
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 SM-10RE is about 30% stronger than the RS version.
Stiffer Spokes
Wheel stiffness matters but it gets overlooked and undiscussed. The redesigned spokes of the SM-10RE are about 20-25% 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.
A Stronger Lightweight Wheel
Our forged Sprint wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we carved out as much material as possible, then we purposefully added one pound back to reinforce critical areas, creating a stronger inner lip and a higher load rating. Whats the point of a lightweight wheel if its fragile?
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 SM-10RE is the extra wide and deep side-milled spokes. Any excess material that doesnt 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 didnt 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. Our new forged wheels are the product of everything weve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles.
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 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 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. Its only a fraction of a pound but its 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 doesnt 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. Dont 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.
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 try to locate and decipher wheel specs that have been hastily hammered into the rim or become unreadable over time. With our 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. (Youre welcome.)
Additional Features
Hub Centric
All EC-7RS wheels are purpose built for select vehicle applications. Very few applications require centering rings.
Center Caps
All APEX wheels come with our gloss black cap included that is interchangeable with the OE cap. We also offer additional colors for select fitments.
Wheel Hardware
APEX wheels can be used with all OEM mounting hardware, proper aftermarket hardware and most wheel spacers. Wheel locks and stud conversion kits also work perfectly.
