Upgrading a YZ-4 with the Yokomo Z4-008FG1 Gull Type F Suspension Arm tightens steering response and helps the car hold its line through fast corners. The gullwing form reduces unwanted flex and improves consistency across lap runs. It is a straightforward route to crisper handling for competitive or club use.
The gull design adds structural strength without sacrificing necessary compliance, improving shock control and traction feel. That translates to more predictable behaviour under braking and during turn-in. Materials and construction target reliable performance under repeated running.
These arms are tailored to fit the Yokomo YZ-4 mounting pattern so they integrate without major chassis changes. Installation uses common tools and can be completed quickly as part of a regular maintenance session.
