AS81487

Overview

The TEAM ASSOCIATED RC8B3.2/RC8B3.2e FT LRC ARM MOUNT D NARROW (AS81487) is a precision-engineered suspension upgrade designed specifically for serious RC buggy racers and enthusiasts in the UK who demand competitive performance on the track. This Factory Team component represents the pinnacle of suspension tuning innovation, allowing you to dial in your RC8 platform with factory-backed engineering that has been proven in competitive racing environments. Whether you're running an RC8B3.2, RC8B3.2e, RC8T3.2, or RC8T3.2e, this low roll centre arm mount is an essential upgrade for anyone looking to gain a measurable advantage through advanced suspension geometry.

As a dedicated RC car UK enthusiast, you understand that marginal gains in handling and traction can make the difference between winning and second place. This FT LRC arm mount delivers exactly that—a scientific approach to rear suspension tuning that increases rear grip whilst reducing turn-in response. The low roll centre (LRC) geometry works by lowering the pill insert position by just 1mm, a seemingly small adjustment that produces significant real-world improvements in corner exit acceleration and overall track grip on low-grip surfaces where traction is at a premium. This is not a basic plastic part; it's precision manufacturing at its finest, machined from solid billet aluminium and finished in distinctive blue anodising with laser etching that makes it instantly recognisable from standard kit components.

If you're serious about competitive RC racing in the UK, whether at your local track or at national events, the AS81487 is an investment in your performance. This is genuine Factory Team equipment, the same suspension technology that professional Associated racing teams use to dominate competitions worldwide.

Key Features

• Low Roll Centre (LRC) Geometry — By lowering the pill insert position by 1mm on both the C and D mounts working together, this arm mount reduces front-end turn-in response and increases rear traction when accelerating out of corners, which is critical for maintaining consistency and speed through complex track layouts.
• CNC-Machined Billet Aluminium Construction — This component is precision-engineered from solid billet aluminium using CNC machinery, ensuring perfect tolerances and repeatability that cannot be achieved with plastic or cast parts, directly contributing to predictable and consistent handling characteristics.
• Blue-Anodised Finish — The professional blue anodising provides excellent durability and corrosion resistance whilst giving the part an unmistakably premium appearance that distinguishes it as genuine Factory Team equipment rather than standard kit parts.
• Laser Etched Identification — Each component is laser etched to clearly distinguish it from standard kit parts, making it easy to identify during setup, maintenance, or when building multiple configurations, and serving as a mark of authenticity and quality.
• Improves Rear Traction on Low-Grip Surfaces — The LRC geometry specifically addresses one of the biggest challenges in RC racing—achieving maximum grip and acceleration on low-traction track surfaces where maintaining rear wheel contact and power delivery are essential for competitive lap times.
• Reduces Turn-In Response — By adjusting the suspension geometry, this mount reduces the initial steering response, allowing for smoother, more controllable entries into corners and reducing the risk of over-steering or losing the rear end during technical sections of the track.
• Factory Team Engineering — This is genuine Associated Factory Team equipment, designed and tested by professional racing teams, ensuring that the geometry and tolerances are optimised for real-world competitive performance rather than being a generic aftermarket solution.
• Compatible with Multiple Models — This single mount works across the entire RC8B3.2 and RC8T3.2 family, including both standard and e-powered variants, making it a versatile upgrade suitable for buggy or track configurations across the full model range.

Technical Performance

The AS81487 FT LRC Arm Mount D Narrow represents a masterclass in precision engineering and suspension geometry optimisation. Manufactured from solid billet aluminium using CNC machinery, this component delivers the kind of manufacturing accuracy that competitive RC racing demands. The blue-anodised finish is not merely cosmetic; it provides robust protection against the wear, dirt, and corrosion that comes with regular track use, ensuring your investment maintains its structural integrity and appearance over extended periods of use. The laser etching serves a practical purpose—it ensures you can quickly identify this as a Factory Team component during complex setup adjustments or when managing multiple suspension configurations for different track conditions. The heart of this component's performance benefit lies in its low roll centre geometry, which works in conjunction with the matching C mount to lower the pill insert position by 1mm. This seemingly minor adjustment has a profound effect on how your RC8 behaves, particularly on low-grip track surfaces where rear traction is the limiting factor in overall performance. By reducing the roll centre height at the rear of the chassis, this mount decreases the lateral forces acting on the suspension during cornering, which translates directly into improved grip and stability when driving on challenging surfaces. The reduced turn-in response means your buggy will be more predictable and controllable during corner entry, reducing the likelihood of the rear end sliding out or the car becoming unstable during aggressive manoeuvres. For competitive RC racing in the UK, where track conditions can vary significantly between venues and weather conditions, this kind of adjustability is invaluable for maintaining consistency and performance throughout a racing season.

Frequently Asked Questions

• Will this arm mount fit my RC8 model? — This FT LRC Arm Mount D Narrow is compatible with the RC8B3.2, RC8B3.2e, RC8T3.2, and RC8T3.2e platforms. If you own any of these models, this mount will fit directly. It's specifically designed as a narrow configuration, so ensure you're purchasing the correct width variant for your setup.
• How much performance improvement will I see from a single arm mount? — This is one component of a complete suspension tuning strategy. When used in conjunction with the matching Mount C (also available as an LRC version), you'll see the full benefit of the 1mm lower roll centre geometry. The improvement is most noticeable on low-grip surfaces where rear traction is limited, and it will help with corner exit acceleration and overall handling consistency. The magnitude of improvement depends on your track surface and driving style, but expect measurable gains in lap time potential.
• Do I need to buy both Mount C and Mount D for this to work? — Yes, for the optimised low roll centre geometry, both mounts should be used together. Mount D is the rear component, and when paired with the matching Mount C, the combined adjustment of 1mm lower pill insert position delivers the intended suspension geometry. You can run Mount D alone as a partial upgrade, but the full benefit is realised with both components installed together.
• Is this suitable for beginners? — This is an advanced suspension component designed for competitive racers and experienced enthusiasts who understand RC suspension geometry and setup. If you're new to RC racing in the UK, we'd recommend starting with standard kit components and developing your driving skills before investing in competitive upgrades like this. That said, once you're ready to take your racing seriously, this is an excellent investment.
• What makes this better than standard plastic arm mounts from the kit? — Factory Team components are engineered from billet aluminium with precision CNC machining, which delivers tighter tolerances, superior durability, and more consistent performance compared to injection-moulded plastic. The blue-anodised finish also provides better corrosion resistance and protection against wear. Most importantly, the low roll centre geometry is a purposeful engineering enhancement that improves handling characteristics, not just a material upgrade.
• Can I use this on both buggy and truck configurations? — The RC8 platform supports both buggy (RC8B3.2/RC8B3.2e) and truck (RC8T3.2/RC8T3.2e) configurations, and this mount is compatible with all variants. The suspension geometry benefit applies to both configurations, though the specific tuning characteristics may vary slightly depending on your setup and driving style.
