Key Features

• Composite PA Material Construction — This suspension arm is manufactured from composite polyamide (PA), a material chosen specifically for its excellent balance of light weight and impact resistance, which means it can absorb the stresses of aggressive driving whilst remaining responsive to suspension geometry changes that affect handling.
• Injection Moulded Precision — The arm is produced using injection moulding techniques that ensure consistent dimensions and material density across every unit produced, resulting in perfect fitment to your vehicle's suspension geometry and eliminating the variability sometimes found in hand-assembled components.
• Lower Rear Position — As the lower rear suspension arm, this component plays a critical role in controlling the rear axle geometry and maintaining proper toe-in settings, which directly influences how your RC car grips during cornering and maintains stability under acceleration and braking.
• Single Unit Design — This package contains one suspension arm, making it perfect for replacing a single damaged component or for hobbyists who prefer to purchase spare parts individually rather than in complete kits.
• Genuine Team Corally Part — As an authentic manufacturer part carrying the official model number C-00180-528, this suspension arm meets all original equipment specifications and comes with the confidence that you're purchasing a component that has been tested and validated by the vehicle's designers.
• Wide Model Compatibility — The HDA-4 suspension system is used across numerous Corally models spanning multiple generations (2020, 2021, 2022 releases), providing excellent versatility whether you own a newly released model or a slightly older platform.

Technical Performance

The Corally HDA-4 suspension system represents a thoughtful engineering approach to 1/10 scale RC car dynamics. The lower rear suspension arm is a critical component in this system, as it directly controls the vertical compliance and geometrical relationship between the rear axle and the vehicle chassis. By utilising composite polyamide material rather than aluminium, Corally has optimised for a combination of light weight, which improves acceleration response and reduces unsprung mass, and controlled compliance, which allows the suspension to absorb small impacts without transferring excessive vibration into the chassis. The injection moulding process ensures that stress concentrations are minimised through consistent wall thicknesses and smooth transitions, improving the arm's resistance to fatigue-induced cracking that can occur with repetitive suspension articulation during intense driving sessions. The engineering of this lower rear position is particularly important because it influences how the rear axle responds to weight transfer during cornering, which affects both cornering speed and the vehicle's tendency to understeer or oversteer. For drivers in the UK RC scene who demand consistent handling characteristics across varied track conditions and driving styles, maintaining genuine suspension components like this arm ensures that your vehicle continues to perform as the designer intended.

Frequently Asked Questions

• What is an HDA-4 suspension arm and why would I need a replacement? — The HDA-4 is Corally's independent double-wishbone suspension system, with the lower rear suspension arm being one of the critical links controlling rear axle geometry. You might need a replacement if your arm has cracked from impact damage, worn down from excessive use, or if you want to upgrade to genuine OEM components to ensure perfect fitment and performance consistency.
• Is this composite arm as durable as an aluminium suspension arm? — Composite polyamide offers different advantages than aluminium; it's lighter which improves overall vehicle responsiveness, and it provides some controlled flex which can help absorb shock loads. However, the trade-off is that composite arms may require more frequent inspection in very aggressive driving scenarios. For most UK RC enthusiasts using their vehicles for recreational bashing or club-level racing, composite arms offer excellent durability and value.
• How do I know this will fit my Corally vehicle? — This arm is designed specifically for vehicles using the HDA-4 suspension system. Check your vehicle's model number against the comprehensive compatibility list provided; if your model is listed, this arm will fit perfectly. The injection-moulded construction ensures dimensional consistency across all units.
• Can I use this as a tuning upgrade even if my vehicle isn't damaged? — Yes, many RC enthusiasts upgrade to fresh suspension components as part of their tuning strategy. Fresh arms with no wear can provide more predictable handling characteristics, and genuine Corally parts ensure you're maintaining the vehicle's original design intent.
• Where should I purchase this suspension arm in the UK? — RC Model Shop stocks genuine Corally spare parts and suspension components, offering the assurance of authentic products and expert support for your RC car maintenance and upgrades.
