Classic Six-Spoke Design with Modern Forged Performance
The RRT Sixer Forged Wheel is a refined interpretation of the traditional six-spoke layout, engineered for drivers who want timeless design combined with modern performance engineering. Built using advanced forging techniques, this forged aluminum wheel delivers strength, reduced weight, and precise fitment for performance-focused vehicles.
Unlike conventional wheels, the Sixer focuses on structural efficiency and material optimization. Every spoke profile, hub transition, and inner pocket is designed to remove unnecessary mass while maintaining rigidity. The result is a lightweight forged wheel that balances aesthetics with measurable performance benefits.
A Classic Wheel Layout Refined for Performance
Six-spoke wheels have long been recognized for their structural simplicity and balanced load distribution. The RRT Sixer Forged Wheel builds on this foundation by introducing modern engineering refinements that enhance stiffness and reduce rotational mass.
The design maintains a clean and recognizable profile while incorporating deeper machining and optimized spoke geometry. This allows the car rim to deliver performance advantages without compromising its classic appearance.
Precision Forged Aluminum Engineering
Each RRT Sixer Forged Wheel is manufactured from high-grade aluminum through a controlled forging and CNC machining process. This method compresses the metal structure, creating a forged aluminum wheel with improved grain alignment and higher strength compared with cast alternatives.
Following forging, advanced machining removes excess material in strategic areas to produce a custom forged wheel that maintains durability while minimizing weight. This process ensures consistency across every wheel produced.
Reduced Mass for Improved Vehicle Response
The Sixer is engineered to function as a lightweight forged wheel, helping reduce rotational mass at each corner of the vehicle. Lower wheel weight contributes to improvements in several areas of vehicle dynamics:
• Faster acceleration response
• More responsive steering input
• Improved braking efficiency
• Reduced suspension workload
These performance gains are especially noticeable in vehicles where wheel weight significantly affects handling behavior.
Available Colors and Finishes
Built for Precise Vehicle Integration
The RRT Sixer Forged Wheel can be configured with a wide range of specifications to suit different vehicle platforms. This flexibility allows drivers to achieve proper stance, clearance, and performance without compromise.
Customization options typically include:
• Multiple wheel widths
• Various offset configurations
• Vehicle-specific bolt patterns
• Center bore options
• Custom finish selections
This level of customization ensures the car rim integrates properly with suspension geometry and brake systems.
