Titan 7 Forged T-D6E 6 Spoke Alloy Wheel Set 18" - Machine Black
Set of 4 wheels - Front, Rear and wheel centres

Front: 9 x 18 ET/offset 48 - PCD: 5 x 130
Rear: 10 x 18 ET/offset 35 - PCD: 5 x 130

Fits:
Porsche 987 Boxster / Cayman
Porsche 981 Boxster / Cayman

The T-D6 represents the culmination of three years of rigorous testing and design refinement. Despite its simple 6-spoke design, the T-D6 is loaded with advanced technical features that elevate our "Forged for All" philosophy to new heights. 
We selected a full-face design to provide a robust foundation for strength and rigidity.

Taking the popular "I-Beam" spoke construction to the next level, we uniquely connected the machining from the hub, spoke, and rim—an innovation that sets us apart in the industry. To balance lightness with strength, we integrated a back rigid spoke tracer, adding stiffness while maintaining a minimalistic design. A slight sliver of material makes a significant impact on performance. Additionally, extensive machining on the backside of the spokes further reduces weight, optimizing the wheel for maximum efficiency.

This cutting-edge design is made possible through the application of 10,000 tons of industry-leading forging force. Signature Titan 7 features include a reinforced inner rim flange for durability, bead seat knurling for enhanced traction, and contrast-machined branding for a distinctive, authentic look that signals serious intent in any vehicle build.

About Alloy Wheels 18"

Alloy Wheels 18" – High-Performance Alloy Wheels for Porsche

Alloy wheels 18" are high-performance wheels designed to support modern tyre profiles, increased brake clearance and enhanced driving dynamics on Porsche models. Commonly fitted to later air-cooled and water-cooled Porsche platforms, 18" alloy wheels deliver a confident balance between performance capability and visual presence.

Manufactured from high-quality aluminium alloys, these wheels offer improved strength, reduced weight and efficient heat dissipation compared to steel wheels. At Design911, we supply a carefully curated range of 18" alloy wheels from trusted manufacturers, suitable for fast-road, performance-focused and modern Porsche builds.

What Do 18" Alloy Wheels Do?

Alloy wheels are engineered to reduce unsprung weight while improving structural rigidity, directly enhancing vehicle handling and braking performance. The 18" size delivers:

• Improved steering precision and high-speed stability
• Reduced unsprung mass for enhanced suspension control
• Increased brake clearance for modern performance braking systems
• Compatibility with wider, lower-profile tyre options

Compared to steel wheels, 18" alloy wheels improve heat dissipation and responsiveness, making them ideal for performance-driven applications.

Why Choose 18" Alloy Wheels?

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

• Lightweight aluminium construction for improved driving dynamics
• A modern diameter suited to performance and handling upgrades
• Compatibility with advanced braking and suspension systems
• A wide selection of contemporary and heritage-inspired designs
• Enhanced stance and visual impact

For many Porsche owners, 18" alloy wheels provide the ideal foundation for modern performance upgrades while retaining everyday usability.

When Should You Fit or Replace 18" Alloy Wheels?

18" alloy wheels are ideal when:

• Upgrading a Porsche for fast-road or performance use
• Installing larger brake systems requiring increased clearance
• Replacing worn or outdated wheels
• Enhancing handling performance and vehicle aesthetics

Choosing the correct 18" alloy wheel helps preserve Porsche balance while unlocking modern grip, braking and stability.
At Design911, our alloy wheels meet strict standards for Porsche fitment accuracy, strength and durability.
