Serpent 990R Rear Low Rollcenter Plate SER903909  [SER903909]

990R rear low rollcenter upgrade plate

This Serpent SER903909 rearplate is a scale replacement made to alter the rear rollcenter geometry on Serpent 990R chassis. It installs as a direct-fit hop-up to modify rear-end behaviour, giving tuners a predictable change in roll center without changing suspension mounts or arms.

Fitment and role: the plate mounts around the rear hub area to lower the rollcenter point, which changes weight transfer and roll characteristics through corners. Use it as part of a measured tuning process, and be aware that rollcenter shifts will interact with anti-roll bars, shock settings, and toe/camber adjustments.

Installation notes: this component replaces the stock 990R rearplate and is fitted where the original plate sits. Confirm fastener lengths and torque to factory guidance, and verify suspension geometry after fitting to maintain correct wheel alignment and droop range.

Use this rearplate to fine-tune rear roll behaviour on Serpent 990R setups, and always re-check suspension geometry following any rollcenter adjustment.
