ac4 forged alloy wheels are manufactured using the forging process making them strong but lightweight for improved suspension response, quicker acceleration, easier braking and faster direction changes. The five twin spoke arrangement extends to the very edge of the rim giving an impression of greater size and is reminiscent of earlier AC Schnitzer designs. The contemporary matt tech gold finish gives stunning good looks and enhanced durability.
