APEX SM-10 Evolution Line | 18" x 8.5" ET35 | 5x120mm | 72.56mm
APEX Race Parts designs and manufactures high performance, flow-formed and forged wheels for a growing list of vehicle makes. They are constantly expanding their product line with new wheel designs, wheel accessories and other performance and race parts. It is their mission to produce and distribute high-quality performance parts that meet the demands of racing and street performance enthusiasts.
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 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.
32mm socket diameter clearance.
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.
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.
A WHEEL YOU CAN DEPEND ON
LIFETIME WARRANTY
All APEX wheels come with a lifetime structural warranty against defects in workmanship and materials, plus a 12 month finish warranty. Exchanges are fast, easy, and hassle-free. Contact us for full terms and conditions for details.
ACCIDENTAL DAMAGE REPLACEMENT
Curb rash or pothole damage on the street? Make an oopsie at the track? We’ve all been there. APEX is proud to offer 50% off replacement wheels, no matter the damage. Contact us for full terms and conditions or for more details.
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.
SO, WHY CHOOSE THE SM-10?
The APEX SM-10 is engineered for drivers who demand more from their wheels.

Whether on the street or at the circuit, the SM-10 is built for real enthusiasts who value performance, precision, and reliability.
Ordered an oil cooler thermostat yesterday, it’s in my hands today, VIC to WA. Unreal service!

Touched base with Sean to do some coding work on my F85 X5M. Not only was he a whiz with the tech stuff, knowing his way around without any difficulty. Very rare to find someone like Sean - I happily rate and recommend this business for anyone.

Andrew Brien @ Southern BM has been helping me for years with my BMWs - he is extremely astute and has a refreshingly customer-first mentality. I trust him to do the best work and only the best!

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!
