Overview

The Fastrax Tamiya TT-02 Aluminium Rear Lower Arm is a premium suspension upgrade component designed specifically for the Tamiya TT-02 chassis platform. This high-quality replacement part is engineered to enhance the handling characteristics, durability and performance of your RC rally car or circuit racer. Whether you're a dedicated RC enthusiast in the UK looking to fine-tune your TT-02 setup, or a serious competitor seeking to extract every last bit of performance from your machine, these aluminium lower arms offer a substantial improvement over standard parts. The TT-02 has become one of the most popular and versatile touring car platforms in the RC hobby, spawning an incredible range of official Tamiya models and enjoying strong support from the aftermarket parts manufacturers. Fastrax is recognised as a leading supplier of high-quality upgrade parts for Tamiya vehicles, and this suspension component is a perfect example of their commitment to engineering excellence.

These rear lower arms are manufactured from precision-engineered aluminium alloy, providing a significant weight and rigidity advantage over the standard plastic components supplied with most TT-02 kits and ready-to-run models. By upgrading your suspension geometry with these arms, you'll notice improved handling response, better cornering stability and more predictable behaviour through fast direction changes. The aluminium construction also offers superior durability compared to plastic arms, reducing the risk of breakage during aggressive driving or when adjusting your setup at the track. For RC car enthusiasts in the UK who demand the best from their TT-02 platform, these Fastrax arms represent a worthwhile investment in reliability and performance.

This is a genuine Fastrax product engineered to exact tolerances to ensure perfect fitment with your TT-02 chassis. The part comes as a pair, giving you both rear lower arms needed to complete the suspension upgrade. Installation is straightforward for anyone with basic RC maintenance knowledge, and the parts integrate seamlessly with both standard Tamiya components and other popular TT-02 upgrade parts available from specialist RC retailers like RC Model Shop.

Key Features

• Aluminium alloy construction — These arms are machined from quality aluminium rather than plastic, which delivers superior rigidity whilst keeping weight to a minimum, resulting in improved suspension response and overall chassis dynamics during competitive driving.
• Precision engineering — Manufactured to exacting tolerances to ensure perfect fitment with the Tamiya TT-02 chassis, guaranteeing smooth operation and reliable performance without modification or adjustment.
• Enhanced durability — The robust aluminium construction resists the impacts and stresses that cause plastic components to crack or fail, significantly extending the service life of your suspension and reducing downtime for repairs.
• Improved handling characteristics — By upgrading to these stiffer, more rigid suspension arms, you'll experience sharper turn-in, better weight transfer through corners and more predictable vehicle behaviour under braking and acceleration.
• Competitive performance upgrade — Designed with input from experienced racers and RC enthusiasts, these arms are commonly used in competitive TT-02 racing to gain an edge in handling and consistency.
• Pair included — You receive both rear lower arms needed for a complete suspension upgrade, so you don't need to buy multiple sets to finish your project.
• Broad compatibility — These arms are engineered to work across the entire Tamiya TT-02 platform, making them suitable for dozens of different official Tamiya models and kits.

Technical Performance

The Fastrax aluminium rear lower arms represent a significant step up from the plastic arms found on standard TT-02 vehicles. Aluminium offers several key advantages over plastic in suspension components: it provides greater torsional rigidity, which means the arms won't flex under cornering loads, resulting in more consistent suspension geometry and predictable handling. The material also dissipates vibration more effectively, translating to smoother feedback through your RC car's behaviour. In terms of durability, aluminium arms will withstand thousands of additional driving cycles compared to plastic equivalents before showing any signs of wear or damage. The precision machining ensures that mounting points are perfectly aligned and holes are precisely drilled, meaning fitment is guaranteed to be accurate with no need for modification. These arms work as part of the complete TT-02 suspension system, which features double-wishbone geometry front and rear. The quality of the aluminium used ensures that even under extreme driving loads—such as those experienced during fast street driving or competitive track racing—the arms maintain their shape and performance characteristics. Many experienced RC car builders in the UK specifically choose Fastrax suspension parts because of their proven track record in both recreational and competitive environments. The rear lower arms are particularly important because they control vertical wheel travel and play a crucial role in maintaining proper camber angles throughout the suspension's range of motion.

Many beginners find that upgrading to quality aftermarket suspension parts significantly improves their driving experience.
• What are the advantages of aluminium arms over plastic ones? — Aluminium offers superior rigidity, meaning less flex under cornering loads, which translates to more consistent handling and predictability. Aluminium also provides better durability and longevity, resisting the impacts and stresses that cause plastic arms to crack or fail. The improved handling characteristics make these arms popular among competitive racers and serious enthusiasts.
• Do I need any special tools to install these arms? — Standard RC tools are sufficient: a screwdriver set, hex wrench set and possibly a small hammer for removing the old arms. No specialist equipment is required, and installation should take less than an hour if you have basic mechanical ability.
• Can I mix Fastrax suspension parts with standard Tamiya components? — Yes, these arms integrate with standard Tamiya suspension parts. However, for the best results and most consistent handling improvements, many experienced builders recommend upgrading multiple suspension components together as a set, as this ensures balanced performance across the entire suspension system.
• Will these arms improve my lap times? — By providing more consistent suspension geometry, better handling response and improved cornering stability, these arms can help you achieve more predictable and potentially faster lap times. The degree of improvement will depend on your driving skill, track conditions and overall vehicle setup.
