The Yokomo Y2-001SDA side diffuser is an RC-scale accessory designed for the YD-2S family of drift chassis. It acts as a lateral aerodynamic rectifier to increase side bite and improve vehicle stability during drifting, helping the chassis produce smoother cornering lines and more predictable transitions.
By reducing the gap between body and chassis on some bodies, the diffuser can raise side panel rigidity and further stabilise drift behaviour. Note that front-side clearance is required for this part, so it cannot be fitted at the same time as the graphite side plate reinforcement bar Y2-002SB.
