Vorsteiner × Gunther Werks GW9-904 Forged Magnesium Monoblock Wheels for Porsche 992 GT3 RS (2022+)

Description

The Vorsteiner × Gunther Werks GW9-904 Magnesium Monoblock wheel set is an ultra-premium, motorsport-grade wheel upgrade tailored for the Porsche 911 GT3 RS (992.1). Forged from aerospace-grade magnesium alloy in a true monoblock design, it massively reduces unsprung- and rotational mass while offering striking visual presence. With staggered sizing (20″ × 10″ front and 21″ × 13″ rear) optimized for the GT3 RS platform, this set delivers sharper handling feel, quicker throttle response and a stand-out finish worthy of a track-ready build.

Fitment Notes

• Designed specifically for Porsche 911 GT3 RS (992.1 generation) — 20″×10″ front, 21″×13″ rear set. 

• Center-lock (or dedicated hub pattern) wheel design — ensure your vehicle’s hub/bolt pattern matches the wheel specification. 

• Special-order product: lead times of 3-8 weeks typical for the magnesium monoblock models.

• Manufacturer finishes (options such as Gunmetal or Pyro Red) as selected at order. 

• Center-lock or hub rings/center pieces appropriate to fitment (if applicable)

• Installation guidance and manufacturer warranty information (lifetime structural warranty claimed for some models)

Product Specs

• Construction Type: Monoblock (one-piece) forged, high-precision manufacturing. 

• Material: Aerospace-grade magnesium alloy for superior strength-to-weight ratio vs typical aluminum alloys. 

• Estimated Weight (example): Front ~15 lbs, Rear ~19.8 lbs

• Front: 20″ diameter × 10″ width; Offset: 43 mm.

• Rear: 21″ diameter × 13″ width; Offset: 29 mm.

Product Features

• Motorsport-Grade Magnesium Forging – The use of magnesium instead of standard aluminum alloys yields meaningful weight savings and enhanced dynamic response. Monoblock Forged Integrity – The one-piece forged construction maximizes structural strength and minimizes flex under load, ideal for high-performance and track conditions.

• Precision Fitment for GT3 RS – Designed and sized for the 992.1 Porsche 911 GT3 RS platform, ensuring correct offset, clearances and optimized handling behaviour.

• Staggered 20″×10″ + 21″×13″ Setup – The aggressive rear width (21×13) improves rear grip and presence, while the front 20×10 strikes a balance between clearance and handling agility.

• High-End Finishes & Exclusivity – Available in premium finishes like Gunmetal or Pyro Red, this wheel set is as much about style and exclusivity as performance.

• Track-Focused Performance Enhancement – By reducing unsprung and rotational mass, the wheel set contributes to faster acceleration, better braking response and sharper cornering feel.
