Key Features

• Precision Aluminium Construction — Manufactured from high-grade aluminium alloy, these rear upper arms are significantly stronger and more durable than the original plastic components, providing better structural rigidity that translates directly to improved handling stability and reduced flex during cornering and acceleration.
• Perfect Fitment for Tamiya TT-02 — Engineered with exact tolerances to ensure seamless compatibility with the Tamiya TT-02 chassis and all its official variants, including the TT-02D Drift Spec and models from major manufacturers like the Tamiya GT-FOUR, Porsche 911 GT3 R, Mercedes-Benz models, BMW M3, Audi models, Honda NSX, and Toyota variants available in the UK market.
• Pair Included — This package includes two rear upper arms (left and right), providing complete coverage for the rear suspension geometry and allowing for consistent performance across both sides of your RC car's rear axle assembly.
• Enhanced Suspension Performance — The rigid aluminium design minimises suspension flex and binding, resulting in more predictable handling characteristics, faster corner response, and improved power delivery from corner exit, which is particularly noticeable when running at competitive speeds on UK racing circuits.
• Lightweight Yet Strong — Despite being constructed from solid aluminium, these components maintain a relatively lightweight profile compared to some alternative upgrade options, ensuring they don't significantly add unsprung weight that would negatively affect suspension response and overall vehicle dynamics.
• Professional-Grade Quality — Fastrax components are recognised throughout the RC hobby as high-quality aftermarket parts that provide genuine performance improvements, with a reputation built on years of successful use in both recreational and competitive racing environments across the United Kingdom and internationally.

Technical Performance

The Fastrax Tamiya TT-02 Aluminium Rear Upper Arm represents a significant upgrade over the standard plastic suspension components supplied with Tamiya TT-02 models. The aluminium construction provides approximately three to four times the rigidity of the original plastic arms whilst maintaining excellent fatigue resistance through multiple seasons of use. The precision engineering ensures that the arms maintain proper suspension geometry under load, preventing the gradual wear and flex that causes handling degradation in plastic components over time. When installed as part of a complete Fastrax suspension upgrade package—including other components such as lower arms, shock absorbers, and driveshafts—these rear upper arms work together to create a fully optimised suspension system that delivers noticeably sharper handling response, reduced body roll during cornering, and more consistent lap times in competitive racing environments. The build quality is exceptional, with precisely machined bore holes that accept standard TT-02 bearings and fasteners without modification. Users throughout the UK RC community have reported that combining Fastrax suspension parts creates a significantly improved driving experience compared to running partially upgraded or standard setups, though for best results it is recommended to upgrade the complete suspension package rather than mixing standard and upgraded components, as this ensures proper geometry and suspension travel characteristics. The material selection—aerospace-grade aluminium alloy—provides excellent durability even during high-speed impacts and aggressive track conditions typical of competitive TT-02 racing in the UK market.

Frequently Asked Questions

• Are Fastrax Tamiya TT-02 aluminium rear upper arms worth upgrading from the standard plastic components? — Yes, absolutely. Users throughout the UK RC community report that upgrading to Fastrax aluminium suspension components delivers noticeable improvements in handling precision, durability, and overall performance. The increased rigidity reduces suspension flex, which translates to more consistent lap times and better predictability in cornering. Many experienced TT-02 racers consider suspension upgrades to be among the most effective modifications available for improving performance on UK racing circuits.
• Will these rear upper arms work with my standard Tamiya TT-02 chassis, or do I need other upgrades? — These rear upper arms are designed for direct bolt-on installation to any standard Tamiya TT-02 chassis without modification. However, for optimal results and to avoid mixing standard and upgraded components, many experienced users recommend upgrading the complete suspension package including front and rear upper arms, lower arms, and shock absorbers simultaneously. This ensures proper suspension geometry and travel characteristics across the entire suspension system.

The material selection and manufacturing tolerances ensure compatibility with standard TT-02 bearings and fasteners whilst providing significantly improved rigidity compared to plastic components.
• Can I mix Fastrax suspension parts with standard Tamiya components? — Whilst it is technically possible to mix components, many users have reported that for best results and consistent handling, it is preferable to upgrade the complete suspension package at once. Mixing standard and upgraded components can result in geometry inconsistencies and suspension travel variations that may not deliver the full performance benefit of the upgrade.
• How do these compare to other aftermarket TT-02 suspension options available in the UK market? — Fastrax has built a strong reputation in the UK RC community for producing quality aftermarket parts with genuine performance improvements. These aluminium arms are recognised as a premium upgrade option with excellent build quality, precise engineering, and proven performance on both recreational and competitive circuits.
• Will upgrading my rear upper arms improve my lap times and handling? — Yes, most users experience noticeable improvements in handling response and precision when upgrading to aluminium suspension components.
