Lightweight wheels with only a few, thin spokes are fine and dandy. Until you drive on South African roads with them using a heavy car with hard suspension. Bent out of shape constantly, they shall be.

Actually, these are BBS. They are forged, not cast Chinese wheels. Hammered like a Samurai sword. (well, not quite) but much tougher than normal aluminium: Forging is a non-cutting forming process for material in a heated, solid condition. In order to generate the highest degree of material density and weight reduction at top performance from our high-strength and durable aluminum or magnesium alloys, they are further enhanced in a complex forging process.

Yes, certainly a forged wheel of the exact same design (amount of material) will be stronger than a cast wheel, but will weigh basically the same.

Usually a forged wheel has thinner spokes (less material) to achieve lightness, but is then at the same strength as the heavier (more material) cast wheel.

Here are examples of the same wheel, one cast and the other forged. Look closely at the forged wheel's spokes...

Cast: BBS Wheel: CI-R - Performance Line

Forged: FI-R
