Stock them as spares for quick maintenance, or use them as part of a comprehensive suspension upgrade strategy to maximise your RC8B4's potential on any terrain.

Key Features

• G10 Material Construction — These inserts are manufactured from rigid G10 composite material, which provides excellent strength and durability whilst remaining lightweight, ensuring your suspension arms maintain their structural integrity under the demanding stresses of competitive RC racing and high-performance driving.
• Set of Two Symmetrical Inserts — Each package contains two identically profiled G10 inserts, providing matched left and right side installation for perfectly balanced suspension geometry and consistent handling characteristics across both rear suspension arms.
• Custom Profiled Design — The inserts are CNC routed to a custom profile that fits precisely into the RC8B4 and RC8B4e rear suspension arms, ensuring a perfect fit without modification and maintaining the integrity of your original suspension components.
• Increased Torsional Stiffness — By adding these inserts to your rear suspension arms, you increase the overall torsional stiffness of the suspension system, which directly translates to more predictable grip and improved handling performance on high-traction surfaces where your RC buggy demands maximum responsiveness.
• High-Grip Surface Performance — These inserts are specifically engineered to enhance performance on high-traction surfaces, making them ideal for clay tracks, carpet surfaces, and other demanding racing environments where suspension flex can compromise handling precision and lap times.
• Complete Mounting Hardware Included — Each insert comes with eight M2.5x6 button head cap screw (BHCS) fasteners, which means you have all the hardware necessary for secure installation—four screws per insert—without needing to source additional fastening components from your spare parts box.
• Factory Team Quality Assurance — As genuine Associated Factory Team parts, these inserts meet the exacting standards demanded by professional RC racers and are manufactured to the same specifications used in competitive racing programmes worldwide.
• Simple Installation Process — The straightforward design allows for quick installation and removal, making these ideal for tuning sessions where you may want to test different suspension configurations to dial in the perfect setup for your particular driving style and track conditions.

Technical Performance

The Team Associated RC8B4 FT Rear Suspension Arm Inserts represent a focused engineering solution to one of the most critical performance variables in competitive RC buggy racing: suspension arm stiffness. Manufactured from G10 composite material, these inserts deliver measurable improvements in torsional rigidity without adding excessive weight that would compromise your vehicle's acceleration, braking response, or overall speed. The 2.0mm thickness of the carbon fibre inserts mentioned in the manufacturer's alternative specifications provides context for the level of engineering precision applied to these components. Each insert is individually CNC routed to a custom profile that matches the internal geometry of the RC8B4 and RC8B4e suspension arms, ensuring a perfect fit that maintains the original design intent whilst adding the stiffness benefit. The inclusion of eight M2.5x6 button head cap screws provides redundant fastening security across both inserts, with four screws securing each component. This builds in safety margins that ensure the inserts remain permanently fixed during high-speed cornering, sudden direction changes, and the repetitive impact cycles that occur during extended driving sessions. The engineering specifically targets high-traction surfaces, where ground grip is maximised and suspension arms are subjected to their greatest torsional loads. On clay tracks, carpet surfaces, and other high-grip racing environments, suspension flex reduces the precision of steering input translation and can lead to inconsistent handling behaviours that cost lap time and control. By increasing torsional stiffness, these inserts ensure your control inputs are translated more directly to wheel positioning, improving predictability and allowing you to maintain throttle application confidence through technical corner sequences where lesser-equipped vehicles would suffer from suspension arm flex.

Frequently Asked Questions

• Are these suspension arm inserts compatible with my RC8B4 buggy? — Yes, these Team Associated Factory Team inserts are specifically engineered to fit the RC8B4 and RC8B4e models perfectly. They are genuine Associated parts designed by the same team that develops the vehicles themselves, so fitment and compatibility are guaranteed without any modification needed to your suspension arms.
• What is the difference between G10 and carbon fibre inserts for RC buggy suspension? — These inserts are manufactured from G10, which is a rigid glass-filled epoxy composite that provides excellent strength and durability. The manufacturer also produces carbon fibre alternatives (2.0mm thickness) for those seeking alternative tuning options, but the G10 material in this package offers robust performance with proven reliability in competitive racing applications.
• Will these inserts improve my lap times on high-traction track surfaces? — These inserts are specifically designed to add torsional stiffness for high-grip surfaces, which translates to more predictable handling and improved steering response precision. On clay tracks, carpet racing surfaces, and other high-traction environments, the increased stiffness helps your RC buggy maintain consistent behaviour through corners, allowing you to brake later and accelerate earlier with greater confidence in your vehicle's responsiveness.
• How difficult is it to install these rear suspension arm inserts? — Installation is straightforward and requires only basic tools to position the inserts and secure them with the included M2.5x6 button head cap screws. The custom profile ensures a perfect fit into your RC8B4 suspension arms, and the simple fastening system means installation and removal can be completed in minutes, making these ideal for tuning sessions where you want to test different suspension configurations.
• Should I use these inserts for bashers or only for competitive racing? — Whilst these are Factory Team parts designed with competition in mind, any RC enthusiast using an RC8B4 or RC8B4e can benefit from the improved handling characteristics they provide. Weekend bashers exploring advanced tuning, hobbyists upgrading their existing RC buggies, and serious racers all use these inserts to enhance their vehicles' performance. The choice depends on whether you want to experiment with suspension tuning and prefer more predictable handling on high-grip surfaces.
• What hardware do I need to install these inserts? — Everything you need for installation is included in the package: eight M2.5x6 button head cap screws (four per insert) provide all the fastening hardware required for secure mounting. You will only need basic tools such as an appropriately sized hex key or Allen wrench to tighten the fasteners.
