Best Forged Wheels for Porsche 911 (992)

Porsche fits the 992-generation 911 Carrera S with staggered 20-inch front and 21-inch rear wheels as standard — a 245/35 ZR20 and 305/30 ZR21 combination that weighs 12.4 kg and 14.1 kg per wheel respectively in cast aluminium. Switching to forged monoblock construction from aerospace-grade 6061-T6 alloy drops those figures to approximately 9.1 kg and 10.8 kg, removing over 12 kg of unsprung mass from a car where every gram is accounted for in the engineering spreadsheet.

This fitment guide covers the 992 platform's unique requirements — including centre-lock versus five-bolt hubs, PCCB (Porsche Ceramic Composite Brake) clearance, and the specific offset windows that maintain factory suspension geometry. All wheels referenced are available through Hodoor Performance's forged wheels collection.

992 Platform Wheel Specifications

The 992 uses a staggered fitment across all variants. The base Carrera runs 19/20 (8.5J front, 11.5J rear), while the Carrera S, GTS, Turbo, and GT3 Touring use 20/21 stagger. The GT3 with track-focused intent runs 20/21 as well but with centre-lock hubs on the Weissach package.

*Centre-lock available on GT3 with Weissach package. Standard GT3 uses five-bolt. The centre bore across all 992 variants is 71.6 mm.

Offset tolerances on the 992 are tight. Porsche engineers the suspension geometry around specific scrub radius values, and deviating more than ±5 mm from factory ET will alter steering feel and tyre wear patterns. For the Carrera S, the safe aftermarket window is ET47–ET53 front and ET62–ET70 rear.

PCCB Clearance: The Critical Constraint

The 992 Turbo S and GT3 ship with Porsche Ceramic Composite Brakes as standard — 410 mm front rotors gripped by ten-piston calipers. These units have a significantly larger envelope than the cast-iron alternative. Any aftermarket wheel must clear 410 mm rotors with a minimum 3 mm gap to the inner barrel.

All forged wheels available through Hodoor Performance are machined to order with individual PCD, DIA, ET, and MaxLoad specifications. This means PCCB clearance is engineered into each set rather than left to aftermarket spacer solutions. Hodoor's technical team verifies caliper dimensions against wheel barrel geometry before production begins — a process that eliminates the trial-and-error approach common with off-the-shelf wheels.

For cars running the standard cast-iron brake package (350 mm front on Carrera, 380 mm on Carrera S), clearance is rarely an issue with 20/21" forged wheels in appropriate offsets.

Top Forged Wheel Options for the 992

Each wheel below is a one-piece forged monoblock from 6061-T6 aviation aluminium. All carry TÜV, SAE, and DOT certification with three-year warranties covering structure and finish.

Solomon Alsberg A1

The A1 is a classically proportioned five-spoke design that mirrors the visual language of Porsche's own Sport Classic wheel. Available from 18" to 22", the 20/21" staggered configuration suits the 992 Carrera S perfectly. Forged from 6061-T6 with CNC precision machining, each set is made to individual vehicle specifications. Weight in 20" front: approximately 8.9 kg. Includes preparation for TPMS sensors and sports brake compatibility.

Beneventi K5S

The K5S delivers a mesh-style design with deep concavity that works exceptionally well on the 992's wide rear haunches. At 21×11.5J, the rear wheels fill the quarter panels without rubbing. Beneventi's ISO-certified production process ensures consistent quality across the set. Includes colour-matched aluminium centre caps and Bimecc Engineering wheel bolts. Available in any standard colour with gloss or matte finish, plus diamond-cut and mirror polish options.

Solomon Alsberg Brooklyn

The Brooklyn is a split-five design available from 19" to 22". Its relatively thin spokes maximise brake cooling airflow — a genuine performance advantage on track-driven 992 GTS and GT3 Touring models. The forged monoblock construction handles track loads without flex. Custom engraving, liquid glass coating, and two-tone colour schemes available.

Beneventi K4.0

A bold multi-spoke pattern that adds visual complexity without excessive weight. The K4.0 is available from 18" to 22" and suits the 992 Turbo's aggressive stance particularly well. Same 6061-T6 forged construction with three-year warranty. Full custom colour palette including combinations with diamond grooves and secondary accent colours.

Centre-Lock Conversion and Five-Bolt Considerations

The 992 GT3 Weissach package uses Porsche's centre-lock hub system — a single large nut per wheel rather than five individual bolts. Centre-lock hubs require specifically designed wheels with a matching taper and torque specification (600 Nm). Not all forged wheel manufacturers support centre-lock; however, all wheels available through Hodoor Performance can be machined for either five-bolt or centre-lock hub configurations.

For owners of five-bolt 992s considering a future centre-lock conversion, note that this requires hub replacement — it's not a simple adapter situation. The investment typically runs €3,000–€5,000 for the hub assemblies alone, plus labour. Most 992 owners outside GT3 Weissach spec are better served by five-bolt forged wheels at the correct offset.

Tyre recommendations for 992 on forged 20/21" stagger: Michelin Pilot Sport Cup 2 for track-focused use, Pilot Sport 4S for road-biased performance. Pirelli P Zero Trofeo RS for GT3 owners chasing lap times. All three brands certify specific sizes for the 992 platform with N-spec markings.

Weight Savings and Performance Impact

On a car weighing 1,515 kg (Carrera S) to 1,640 kg (Turbo S), unsprung mass reduction has a measurable effect on lap times. Engineering data from Porsche's own Weissach development centre indicates that every 1 kg reduction in unsprung mass per corner is equivalent to approximately 3–4 kg of sprung mass reduction in terms of dynamic performance.

A set of forged 20/21" wheels saving 3 kg per corner therefore delivers a dynamic equivalent of roughly 45–50 kg of total weight reduction. That's the difference between a Carrera S and a Carrera S with half a fuel tank. On the Nürburgring Nordschleife, that translates to approximately 1.5–2.0 seconds per lap according to published simulation data.

Beyond lap times, the reduced rotational inertia improves throttle response, gear change feel, and ABS intervention precision. The 992's sophisticated PSM (Porsche Stability Management) system was calibrated for factory wheel weights — giving it lighter wheels to work with only improves its effectiveness.
