A Bold Take
Aesthetically, the SL-12RT blends the machined lip geometry of the ML-7RT with an entirely new visual identity, thanks to the 12-straight spoked design. It’s a look that gives this wheel a muscular presence—distinct from the flowing forms of the ML-10RT and ML-7RT while adding another option to the lineup. This is a wheel that brings a fresh aesthetic to select vehicle applications—filling a style gap in the Apex catalog, while staying true to our Real Performance ethos. Its design stands out as one of the most distinct in our lineup, representative of a unique, original design backed by Real Performance.
Side-Milled Spokes
The SL-12RT features Apex’s signature extra-deep, side-milled spokes—an aggressive weight-saving measure achieved through precision CNC ball cutting. Every surface is carefully machined to remove material that doesn’t contribute to strength, resulting in meaningful weight reduction without compromise. While others may imitate the visual of side-milling, these executions are often shallow or purely cosmetic—failing to deliver any real performance benefit. Our approach is fundamentally different: engineered with intent, not just for appearance.
The result is a lighter, stronger wheel with a sharper, more defined spoke profile that adds both visual depth and functional advantage.
Sprint Inner Lip
The SL-12RT borrows the race-proven Sprint Spec inner lip from our Sprint Line wheels, providing critical strength to the unsupported inner lip of the wheel. Adding 32% more material where it matters most. Don’t settle for under-engineered wheels, attack both the track and your cities potholes with confidence.

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.
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 Touring Line wheels are independently tested by ITS at their Michigan facility following JWL standards but pushed to much higher loads and much longer durations.
Machined Lip
An evolution of the original Apex Machined Lip, the SL-12RT features a revised interface between the face and outer lip for a more aggressive, purposeful appearance. Like the SL-12RT, every SL-12RT maintains a consistent 1.5" outer lip across all sizes—giving even conservative fitments the bold, deep-lip look enthusiasts expect. More aggressive fitments build on this foundation, maximizing spoke concavity to create an ultra-aggressive profile while maintaining visual harmony with narrower, staggered applications.
Vehicle Specific Spoke Profiles
The lipped design of the SL-12RT inherently limits brake clearance. Rather than making every fitment as conservative as possible, we utilized our extensive 3D vehicle scanning library to shrink wrap each fitment's spoke design around respective OEM and popular aftermarket brake kits. Leveraging our vehicle research and engineering team, we find a perfect balance of concavity and brake clearance.
Built for Impact Sockets
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.

OEM Center Cap Compatibility
Love that OEM+ look? Us too. Our engineers went the extra mile and incorporated a flush mounted OEM center cap support into the ML-10RT. Whether you want to show off your included Apex center caps or stick with your OEM caps, the SL-12RT will seamlessly accept both.
Laser-Engraved Specs
As car 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 Touring Line wheels have laser-engraved specs on the barrel, in plain sight, making them easy to find and read.
Additional features
Hub Centric
All Forged Touring Line wheels are purpose built for select vehicle applications. Very few applications require centering rings.
Center Caps
All Apex Forged Touring Line 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
Wherever possible, Apex wheels are designed to be used with OEM mounting hardware as well as high-quality wheel spacers, stud conversion kits, wheel locks, and more. See our Accessories pages.
TPMS
All Apex wheels accept OEM and aftermarket Tire Pressure Monitoring Sensors and standard fit valve stems. If you don’t have sensors, then select from our metal stems available in multiple finishes.
