SW20
Clean lines.
Versatile build.
The SW20 delivers a clean, modern aesthetic with a strong performance edge. Featuring an elegant split-spoke design with a deep concave profile, available in Hyper Black or Matte Black. A lightweight, versatile wheel suited to street and track builds alike.
Construction
Flow‑Formed Alloy
Why flow‑formed?
After the face is cast, the barrel is heated and spun at high speed while rollers apply pressure — stretching and compressing the metal so its grain aligns. That typically makes a flow-formed wheel lighter and stronger than an equivalent cast-only wheel, without the cost of a fully forged one. Exact weight and strength gains vary by design.

GOOD TO KNOW
Will these fit my car?

Yes. Every SpeedWorks wheel is independently tested and certified to JWL, VIA, and AS1638 which are the safety standards required of road wheels internationally and in Australia. That's your assurance these are built for daily driving, not just for looks. Just make sure your chosen size and offset suit your vehicle and your state's fitment rules.

What does flow formed mean?
This is a flow formed wheel. After casting, the barrel is spun under high heat and pressure, stretching the alloy so its grain structure aligns. The result is a wheel that's significantly stronger and lighter than standard cast, giving you performance closer to forged without the forged price tag.
