21-inch Turbo GT lightweight summer forged wheel set with track tyres. 


porsche

Fits:

Porsche Taycan Turbo GT 
(MK2) 2024 Onwards
Porsche Taycan Turbo GT with Weissach Package  (MK2) 2024 Onwards

Weight-optimised, forged alloy wheels with rear-milled spokes, one-piece, painted in black (satin-gloss) with track tyres.

The focus of the mounted track tyres is on race circuit use. The grip level between the road and tyres is significantly increased due to a changed tyre mix. In combination with optimisation of the profile depth, this results in improved performance. These road-approved tyres therefore offer improved properties on a dry circuit, but with drawbacks on a wet circuit.

Front axle:
 9.5 J x 21 RO 60 with tyres 265/35 ZR21 101 Y XL (track tyres)
Rear axle: 11.5 J x 21 RO 66 with tyres 305/30 ZR21 104 Y XL (track tyres)

About Alloy Wheels 21"

Alloy Wheels 21" – Premium Performance Alloy Wheels for Porsche

Alloy wheels 21" are premium performance wheels engineered to deliver maximum road presence, enhanced handling stability and increased brake clearance on modern Porsche models. Commonly fitted to high-performance and luxury Porsche platforms, 21" alloy wheels support wide, low-profile tyres and advanced braking systems while maintaining confident steering response and high-speed control.

Manufactured from high-quality aluminium alloys, these wheels offer an optimal balance of strength, reduced weight and effective heat dissipation compared to steel alternatives. At Design911, we supply a carefully curated range of 21" alloy wheels from leading performance manufacturers, designed to meet Porsche fitment standards and modern performance expectations.

What Do 21" Alloy Wheels Do?

Alloy wheels are designed to reduce unsprung weight while increasing rigidity and braking capability, directly enhancing vehicle dynamics. The 21" size delivers:

• Improved high-speed stability and steering precision
• Reduced unsprung mass for better suspension control
• Increased brake clearance for large performance braking systems
• Compatibility with wide, ultra-low-profile modern tyre options

Compared to smaller wheel sizes or steel wheels, 21" alloy wheels provide enhanced responsiveness, braking performance and a commanding visual stance.

Why Choose 21" Alloy Wheels?

21" alloy wheels are chosen by Porsche enthusiasts because they offer:

• Lightweight aluminium construction for performance driving
• A large diameter suited to modern and high-output Porsche platforms
• Compatibility with high-performance tyres and advanced brake systems
• A wide range of premium, luxury and motorsport-inspired designs
• Exceptional road presence and contemporary styling

For many Porsche owners, 21" alloy wheels deliver the ultimate blend of performance capability, luxury appearance and modern Porsche aesthetics.

When Should You Fit or Replace 21" Alloy Wheels?

21" alloy wheels are ideal when:

• Upgrading a Porsche for maximum visual impact and performance
• Installing large brake systems requiring increased clearance
• Replacing worn or non-original wheels
• Enhancing both handling performance and modern vehicle aesthetics

Selecting the correct 21" alloy wheel helps preserve Porsche handling balance while unlocking improved grip, braking performance and stability.
At Design911, our alloy wheels meet strict standards for Porsche fitment accuracy, strength and durability.
