Product Information
APEX FLOW FORMED EVOLUTION LINE SM-10
The APEX SM-10 is part of the Evolution Line of flow-formed wheels and represents the next evolution in APEX’s commitment to real performance. Designed using motorsport-inspired engineering, the SM-10 combines aggressive styling with enhanced strength, reduced weight, and superior brake clearance. Every detail — from its “I-beam” spoke design to its reinforced inner lip — was purpose-built to deliver uncompromised performance for both street and track applications.
SM-10 HIGHLIGHTS
- I-Beam spokes for reduced weight
- Reinforced inner lip for strength
- Massive brake clearance
- Independently tested and certified
- Unmatched replacement program
- Lifetime structural warranty
SM-10 FEATURES
THE FLOW FORM ADVANTAGE
Flow forming enables APEX to produce high-performance wheels without the price premium of forging. The process improves the mechanical properties and grain structure of the barrel, increasing both strength and stiffness, which allows for less material use and reduced weight. Through advanced engineering, APEX flow-formed wheels achieve a higher load rating than some competitors’ forged wheels.
"I" BEAM SPOKES
One of the most prominent features of the SM-10 is its advanced "I" beam spoke machining. Any excess material that doesn’t add strength is carved out from the sides of the spokes using a precision CNC ball cutter. This process is often deemed cost-prohibitive by others, but for performance without compromise, APEX believes it's essential.
BIGGER, TOUGHER INNER LIP
The inner lip is the most vulnerable part of a wheel because it has no spokes for support. The APEX Flow Formed Evolution Line adds more material to this high-impact area as an extra layer of protection against track berms, potholes, and whatever else the road may throw at it.
MAXIMISING CONCAVITY
APEX uses the deepest concave face profiles possible for every application after factoring in critical clearances such as brake calipers. The SM-10 utilises three unique profiles to achieve this, with the deepest concave face delivering reduced weight and a stunningly aggressive appearance.
BIG BRAKE CLEARANCE
Big brakes often require bigger, heavier, more expensive wheels, which aren’t ideal in a performance environment. The SM-10 is one of APEX’s many wheels designed to solve this problem. Through comprehensive laser scanning and extensive rounds of test-fitting, APEX has created 18” wheels that clear large brake systems which typically require 19” wheels from other manufacturers.
WEIGHT OPTIMISED
APEX conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and remove any extra material where it did not improve strength. The result is a wheel that is exceptionally light without the strength compromises typically found on lightweight wheels
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.

FINISHING TOUCHES
The SM-10 is finished using a multi-stage liquid paint over a powder-coated base coat. This coating process leaves lug holes, centre bores and mounting pads untouched, which ensures proper fit and torque values.
JWL AND BEYOND
All APEX Flow Formed wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.
TRUE VIA
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified and even use the VIA stamp without permission. APEX flow formed wheels have been certified, and the company provides the registration numbers for every wheel. Customers should protect themselves and demand registration numbers from manufacturers.
ADDITIONAL FEATURES
HUB CENTRIC
All SM-10 wheels are purpose built for select vehicle applications. Very few applications require locating rings.
CENTRE CAPS
All APEX wheels come with a gloss black cap included that is interchangeable with the OE cap. APEX also offer additional colours 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.
TPMS
All APEX wheels are compatible with both OEM and aftermarket Tyre Pressure Monitoring Systems (TPMS), as well as standard-fit valve stems.

REAL DRIVERS NEED REAL PERFORMANCE
Not all claims of performance are backed up by facts — and it's a big problem. APEX defines real performance through wheels that are precisely engineered, rigorously tested, and objectively measured. Unlike under-engineered “fashion” wheels that overpromise and underdeliver, APEX wheels are designed for genuine performance, backed by independent testing and verifiable results.
