Targeted at racers refining corner entry and mid-corner balance, the 3Racing Tiny KPI Knuckle installs on the KIT-D4ARWD Sakura D4 AWD chassis to provide a more precise steering baseline. These black knuckles are intended to integrate with standard steering geometries while enabling tighter control during tune adjustments. 3Racing designs this part to deliver predictable feedback that aids setup decisions at the track.
