Porsche 911 991 Turbo S – 20 Inch Wheel Set | ET51 / ET56 | OEM Specification | Direct Fitment

Elevate the stance, presence, and dynamic performance of your Porsche 911 991 Turbo S with this genuine 20 inch wheel set in staggered ET51 front and ET56 rear offset specification — a factory-grade, precision-engineered wheel upgrade that delivers the commanding, wide-stance visual authority and the precise suspension geometry integration that the extraordinary performance credentials and aerodynamic sophistication of the 991 Turbo S demand and deserve. The definitive factory wheel set for the 911 991 Turbo S — combining the visual drama of the Turbo S-specific wheel design with the precise ET51 and ET56 offset specification that optimises handling, traction, and the legendary Turbo S performance character.
These are 100% genuine OEM Porsche 911 991 Turbo S 20 inch alloy wheels in the factory-correct staggered ET51 front and ET56 rear offset specification — not aftermarket copies, non-Turbo S specification wheels, or inferior substitutes of any description. The 991 Turbo S wheel specification is one of the most precisely engineered and most carefully optimised wheel and suspension geometry configurations in the entire Porsche model range — the result of Porsche’s exhaustive chassis development programme for the 991 Turbo S that has determined the exact wheel width, diameter, offset, and tyre section width combination that delivers the optimal balance of lateral grip, steering precision, ride quality, braking performance, and the extraordinary all-weather traction of the Porsche Traction Management all-wheel drive system across the full performance envelope of one of the world’s fastest and most capable production cars.

The staggered offset configuration — ET51 at the front and ET56 at the rear — is a critically important and precisely engineered specification detail of the 991 Turbo S wheel package that ensures the correct wheel track width, optimal suspension geometry, and precise load distribution across the front and rear axles of the Turbo S. The front ET51 offset positions the front wheels at the precisely correct track width for optimal steering geometry, front axle traction under the AWD system’s torque distribution, and the precise, communicative, and confidence-inspiring steering feel that the 991 Turbo S delivers. The rear ET56 offset positions the wider rear wheels at the factory-correct track width for optimal rear axle traction, maximum rear contact patch effectiveness under acceleration, and the wide, planted, and thoroughly purposeful rear stance that is the visual signature of the Turbo S specification 911.
The 20 inch diameter of these genuine Turbo S wheels is the factory-specified optimal size for the 991 Turbo S platform — large enough to accommodate the substantial brake caliper assemblies of the Turbo S braking system, to deliver the commanding wheel arch fill and visual presence that the Turbo S wide-body demands, and to provide the tyre profile and contact patch characteristics that work in complete harmony with the 991 Turbo S’s sophisticated all-wheel drive, active suspension, and dynamic chassis management systems. The Turbo S-specific wheel design — with its distinctive aerodynamic spoke geometry, precision-machined alloy construction, and the characteristic Turbo S visual identity — creates a wheel of genuine visual impact and engineering purposefulness that perfectly complements the wide, muscular, and thoroughly purposeful body of the 991 Turbo S.
Whether you are replacing damaged or kerbed original Turbo S wheels, upgrading from a smaller specification, completing a full seasonal wheel change, or seeking the definitive factory Turbo S wheel set for your 991, this genuine 20 inch ET51/ET56 wheel set represents an outstanding, authentic, and genuinely compelling opportunity.
