Serpent 903909 Rearplate LRC 990R rear low rollcenter plate  [SER903909]

Rear low rollcenter plate for 990R

This Serpent SER903909 rearplate is an RC-scale replacement designed to change the rear rollcenter geometry on Serpent 990R chassis layouts. The part is intended as a direct-fit hop-up to alter rear-end behaviour, giving tuners a predictable change in roll center without modifying suspension mounts or arms.

Fitment and role: the plate locates at the rear hub area to lower the rollcenter point, affecting weight transfer and roll characteristics during cornering. Use it as part of a measured tuning process, noting that changes to rollcenter will interact with anti-roll bars, shock settings, and toe/camber setup.

Installation notes: this is a component-level replacement for the 990R rear assembly, installed where the stock rearplate sits. Check fastener lengths and torque to factory recommendations, and verify suspension geometry after fitting to ensure wheel alignment and droop range remain within acceptable limits.

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