Sparko F8 Adjustable C-Hub System | Suspension Arm Upgrade
Taiwanese Buggy manufacturer Sparko has released new options for its successful F8 1:8 Buggy platform in the form of a new Adjustable C-Hub System and Suspension Arm Upgrade. The Aluminium Adjustable C-Hub System offers three caster options in one system giving racers greater tuning flexibility with interchangeable inserts that allow you to quickly change caster angles between 18°, 20°, and 22° to suit different track conditions and driving styles. The new upper and lower link mounting positions are engineered to complement Sparko’s 0°, 4°, and 7° KPI steering knuckle system. As caster and KPI settings are changed, the adjustable link positions help maintain the intended geometry, while expanding front-end tuning options.
Sparko’s new Suspension Arm Upgrade features a built-in 2mm adjustment range, allowing you to slide the C-Hub forward or rearward to change the vehicle’s effective wheelbase. Dial in your wheelbase on the fly by shifting the C-Hub’s mounting position directly along the lower arm. Racers can easily alter the buggy’s handling dynamics without swapping major chassis components, the C-Hub shifted forward (+2mm) lengthens the wheelbase. This setup maximises straight-line stability and linear steering feel, keeping the car planted on high-speed sweeps and rough, blown-out track surfaces. The C-Hub shifted Rearward (-2mm) shortens the wheelbase, this configures the buggy for maximum agility, delivering razor-sharp corner entry and rapid direction changes on tight, technical tracks. To give racers even more fine-tuning capability, these new arms will be available in two distinct material hardness options: S (Soft) which optimised structural flex and is ideal for low-traction or bumpy tracks, enhancing mechanical grip and making the buggy more forgiving to drive. H (Hard) delivers maximum structural rigidity which is perfect for high-grip, high-temperature, or high-speed tracks where precision, sharp steering, and instant response are required. Produced from Sparko’s premium high-impact composites, these arms ensure the C-Hub locks securely in place with zero slop.
