The GT5 Black Machined combines a classic five-spoke design with a sharp black and machined finish.

Its strong spoke profile and clean 17-inch proportions give old-school muscle cars and street machines a tougher, more contemporary appearance without losing their classic character.

At OS Formula Wheels, we use the latest wheel-manufacturing technology to produce classic designs, then custom-machine them to fit old-school cars properly.

MADE TO SUIT YOUR CAR

All of our GT5 Black Machined wheels are manufactured as blank fitment, allowing us to custom-machine them specifically for your vehicle.

Depending on wheel size and application, we can customise:

• 5-stud bolt patterns (PCD)

• Offset

• Backspacing

• Centre bore

• Staggered front and rear combinations

Before machining your wheels, we’ll contact you to confirm your vehicle and fitment details.

Not sure what you need? That’s exactly what we’re here for.

AVAILABLE SIZES

17" GT5 Black Machined

• 17" x 7" — PCD: Blank — Offset range: 0 to +25

• 17" x 8" — PCD: Blank — Offset range: 0 to +20

The two available widths allow matching or staggered front and rear combinations, depending on your vehicle and required fitment.

BLACK MACHINED FINISH

The GT5 features a bold black machined finish that highlights the wheel’s five-spoke design.

The dark painted sections provide contrast, while the machined surfaces add definition and give the wheel a clean, high-impact appearance.

It is an ideal choice for drivers wanting classic muscle-car styling with a more modern edge.

FULL CUSTOM

We specialise in 2 or 3-piece one-off special orders in any design you want.

• 15" to 23" with fully custom offsets and backspacing

• Beadlock / Drag setups

MUSCLE-CAR STYLE. CUSTOM FIT.

GT5 Black Machined wheels can suit a wide range of old-school and classic vehicles, including selected:

Holden — Early Holden, Torana, HK–WB, Commodore and more
Ford — Falcon, Mustang and other classic Ford models
Chrysler / Valiant
Chevrolet and American muscle cars
Japanese classics
British and European vehicles

Because classic cars are often modified, we confirm the important measurements before machining.

Brake upgrades, suspension changes, replacement differentials, shortened axles and modified bodywork can all affect the correct wheel fitment.
