Something you need to know about the
Not all wheels are created equal.
Here's what the market won't tell you.
THREE PATHS.
ONE RIGHT ANSWER.
Walk into any wheel shop and you'll hear "forged" used to describe almost everything. Cast, flow formed, fully forged — the terminology is deliberately blurred to justify pricing. Here's the honest breakdown.
Molten aluminum poured into a mold. Fast, cheap, structurally unpredictable. Random grain, micro-voids, no directional strength.
Rim is spun under pressure rollers — better barrel strength. Center face stays cast. A half-measure dressed up as an upgrade.
Solid billet, extreme press force, uniform grain throughout. Zero voids. The only construction we build.
SPLUX Forged
Every wheel starts with a choice
about what to compromise on.
CAST
WHEELS
Molten aluminum is poured into a mold and left to cool. The result is a random, porous grain structure with inconsistencies distributed throughout the entire wheel.
Under cyclic stress — potholes, high-speed sustained loads — those voids become crack initiation points. Cast wheels don't warn you before they fail.
Loose · Porous · Inconsistent
Mold prep → Molten Al pour → Gravity fill → Cool & eject → Minimal machining
Cast blank → Heat rim → Spin-press barrel → Machine face → Finish
FLOW FORMED
WHEELS
Starts as a cast wheel. The rim barrel is heated and pressed against rollers while spinning — creating a denser, more aligned grain in the barrel only.
The center face remains cast. Better rim, same unpredictable center. Marketed as forged-adjacent — the structural foundation is still a casting.
Denser rim · Cast center · Mixed uniformity
FULL FORGED
WHEELS
A solid 6061-T6 billet is compressed under up to 12,000 tons of force at forging temperature. Every molecule is forced into a dense, directional, uniform grain — throughout the entire wheel, not just the rim.
No voids. No casting porosity. No structural inconsistencies. CNC machining then reveals the final geometry from this uncompromising foundation.

Three things we refuse
to compromise on.
THREE THINGS
WE DON'T
COMPROMISE ON.
Full forging is the foundation. What separates a SPLUX wheel from every other forged wheel on the market comes down to three decisions we made — and refuse to walk back.
Not all aluminum is equal. 6061-T6 is aerospace-grade — heat-treated after forging for peak strength-to-weight ratio. Tensile strength up to 310 MPa. The same alloy used in aircraft structures, high-speed rail, and precision engineering.

8,000T
6,000T
Higher tonnage = denser grain compression. At 12,000 tons, molecular alignment reaches its peak — delivering measurably higher fatigue resistance and consistent performance across the entire wheel.
We begin with a 130 lb aluminum billet. 80% of the starting material is removed by CNC — precisely, not approximately. The finished wheel: 26 lbs.
If production lead time is less than 4 weeks, most wheels in the market are made from pre-stocked semi-finished blanks. These blanks may develop internal stress due to unstable storage conditions over time. At SPLUX, every custom wheel is forged from fresh 6061-T6 billets produced in the current month — ensuring optimal material stability and structural integrity.
When you buy SPLUX, you aren't buying a wheel.
You're buying a promise.
Most brands offer 3–5 years strucural warranty, but in SPLUX we offer lifetime structural warranty. Because we build wheels we're confident will outlast the car they're on. For our RCF series, we provide an Unlimited, No-Questions-Asked Warranty for one year (limited to one free replacement).
Our wheels are DOT & TÜV verified and rated at 4.5× the required load — engineered to absorb the kind of impact shown above without structural failure.
Not compliance. Genuine confidence.
We go beyond selling wheels. SPLUX delivers a complete custom
solution — design consultation, engineering adjustments,
manufacturing, and dedicated personal service through every stage
of your build.
Our goal is to build a long-term relationship with you and deliver the best possible experience.
Every line, every detail, every finish — built with purpose.
Your build. Our obsession.
