AS91875

Overview

The Associated B6.3 FT Top Plate & Ballstud Mount Carbon AS91875 represents the pinnacle of performance-focused RC upgrades for competitive enthusiasts and serious hobbyists across the UK. This Factory Team specification component is engineered specifically for the B6.3 platform and related Associated vehicles, offering a premium carbon-fibre composite construction that delivers uncompromising weight savings without sacrificing structural integrity. Whether you're competing at the track or pushing your RC buggy to the limit during weekend bashing sessions, this carbon composite top plate and ballstud mount assembly provides the high-performance edge that separates winning setups from the rest.

Team Associated has earned its reputation as one of the most respected manufacturers in the RC industry, and this carbon-composite option part exemplifies their commitment to engineering excellence. The AS91875 is perfect for RC enthusiasts in the UK who demand the best performance from their vehicles and aren't willing to compromise on quality or durability. This is not a basic plastic component—it's a Factory Team specification upgrade that combines cutting-edge material science with precision manufacturing to deliver genuine performance benefits on track or off-road.

If you're running an RC10B6.3, RC10SC6.2, RC10T6.1, RC10T6.2 or any of the compatible B6-platform vehicles, upgrading to this carbon-fibre top plate and ballstud mount is one of the most effective ways to improve your chassis rigidity, reduce unsprung weight, and achieve more predictable handling characteristics. RC car UK enthusiasts have long understood that weight reduction at the top of the chassis directly translates to improved responsiveness and corner speed.

Key Features

• Carbon-Fibre Composite Construction — This component is manufactured from injection-moulded material that has been impregnated with rigid, lightweight carbon fibres, creating a matrix that delivers superior strength-to-weight ratio compared to standard plastic alternatives. The result is a top plate and ballstud mount assembly that weighs significantly less than conventional options whilst maintaining exceptional structural rigidity under load.
• Factory Team Specification — As an official Factory Team option part from Team Associated, this component has been developed and tested to the same exacting standards used in professional racing programmes. This means you're getting a part that has been validated for competitive use and engineered to withstand the demands of serious RC competition.
• Optimised for B6.3 Platform — This top plate and ballstud mount has been specifically designed around the geometry and mounting points of the B6.3 chassis, ensuring perfect fitment and optimal performance characteristics without requiring modifications or workarounds.
• Weight Reduction Benefits — By replacing heavier plastic components with carbon-fibre composite, you'll achieve measurable improvements in vehicle dynamics. Lower unsprung weight improves suspension response, whilst reduced mass at the top of the chassis lowers the centre of gravity and improves cornering performance.
• Extended Model Compatibility — This component is designed to fit multiple vehicles in the Associated range, making it a versatile upgrade option if you run several B6-platform vehicles or plan to expand your collection.

Technical Performance

The AS91875 top plate and ballstud mount assembly demonstrates Team Associated's mastery of advanced materials engineering. The injection-moulded carbon-composite construction utilises rigid carbon fibres dispersed throughout the polymer matrix, creating a material that is approximately 30% lighter than equivalent plastic components whilst offering superior stiffness and dimensional stability. This weight reduction is concentrated at the highest point of the chassis, which creates a multiplicative effect on handling characteristics—lowering the centre of gravity, improving weight transfer during cornering, and reducing gyroscopic effects that can destabilise the vehicle during rapid direction changes. The material's inherent rigidity also means there's less flex during aggressive driving, translating to more consistent and predictable handling lap after lap. For competitive racing in the UK RC scene, where milliseconds separate winning times from second place, this kind of precision engineering makes a tangible difference. The ballstud mount integration ensures smooth, consistent suspension articulation without the wear and play development that can occur with lower-quality plastic alternatives. This component is designed to work seamlessly with the existing B6.3 suspension geometry and has been engineered to maintain optimal anti-roll bar and steering geometry under all driving conditions.

Frequently Asked Questions

• Which Associated RC buggy models is this carbon top plate compatible with? — This component is designed to fit the RC10B6, RC10B6 Club Racer, RC10B6.1, RC10B6.1D, RC10B6.1DL, RC10B6.2, RC10B6.2D, RC10B6.3, RC10B6.3D, RC10SC6.1, RC10SC6.2, RC10T6.1 and RC10T6.2. If you're unsure whether your specific model is compatible, our experienced team at RC Model Shop in Walsall can advise you immediately.
• What performance benefits will I notice from upgrading to a carbon-composite top plate? — The primary benefits are weight reduction, improved chassis rigidity, and better suspension response. Because the carbon-composite material is significantly lighter than plastic whilst being stiffer, you'll experience improved handling consistency, faster corner speeds, and more predictable vehicle behaviour during aggressive driving. Competitive racers typically notice tighter steering response and more stable mid-corner behaviour.
• Is this a Factory Team genuine part? — Yes, the AS91875 is an official Team Associated Factory Team specification component, meaning it has been engineered and tested to professional racing standards. It's a genuine performance upgrade, not an aftermarket copy.
• Can a beginner RC enthusiast benefit from this upgrade? — While this is technically suitable for any builder working on a compatible B6-series vehicle, it's primarily designed for competitive racers and experienced enthusiasts who have the knowledge to identify performance improvements. Beginners might find better value in learning their current vehicle's characteristics before investing in premium carbon upgrades.
• How much lighter is the carbon version compared to the standard plastic top plate? — The carbon-composite construction is approximately 30% lighter than equivalent plastic components. This translates to a measurable reduction in vehicle weight, which creates tangible benefits in acceleration, braking, and cornering performance.
• Is this part difficult to install? — Installation is straightforward for anyone comfortable working with Associated RC vehicles. The carbon top plate and ballstud mount use the same mounting points as the standard plastic versions, so no modifications to your chassis are required. Simply remove the old component and install the new carbon part using the existing fasteners.
