The 3RACING Cero Rapid 1.0mm Lower Suspension Spacer, model SAK-C168C, is a small but effective tuning component intended for racers focused on setup refinement. It provides a defined change to lower link position to influence roll behaviour and transient response.
In tuning terms, a 1.0mm spacer modifies the lower mount height enough to affect roll centre and leverage ratios. That change can be used to fine-tune understeer characteristics and improve consistency through a sequence of corners.
Best used on Cero Rapid platforms and compatible chassis with similar lower link geometry. Confirm mounting dimensions and suspension travel to ensure the spacer does not introduce binding or exceed recommended clearances.
Fit the spacer on a calibrated bench, torque fasteners to manufacturer recommendations, and validate full suspension articulation. Follow up with controlled track testing to record measurable changes before committing to further setup adjustments.
