3SDM URQ

Origin and purpose. The 3SDM URQ Cast is a faithful reproduction of the original Audi UR Quattro OEM alloy wheel, cast in aluminium and engineered to solve a longstanding problem for UR Quattro owners: the increasing scarcity and cost of the original 15-inch tyres and the limitation of using modern braking systems on the original wheel diameter.

Design highlights. The URQ Cast retains the classic five-spoke styling of the iconic Audi UR Quattro factory wheel, scaled to 16 inches for expanded functionality. The design honours the original aesthetic while enabling a broader choice of tyres and compatibility with larger braking systems — without compromising the period-correct appearance of the car.

Construction and materials. Cast from high-grade aluminium alloy as a monoblock unit, the URQ is manufactured to precise dimensions to match the original OEM specification of the Audi UR Quattro. The 16×8 sizing provides the dimensional step needed to accommodate modern tyre choices while preserving the visual character of the classic design.

Sizes and specifications. Available in a single size: 16×8.0, with 5×112 bolt pattern and ET24 offset. Centrebore is 57.1 mm. Load rating is 675 kg per wheel. These specifications are specific to the UR Quattro platform and have been chosen to match the original fitment as closely as possible.

Available finishes. The URQ Cast comes in two finishes: Zermat Silver and White. Both colours reflect the original factory colour options available on the Audi UR Quattro, allowing a historically accurate restoration or period-inspired build.

Vehicle compatibility. Designed specifically for the Audi UR Quattro (Ur-Q), this wheel is a direct application product. The upgrade to 16 inches allows owners to use a broader range of modern tyres compared to the original 15-inch OEM size, and accommodates larger braking systems while maintaining the original classic wheel look.
