For racers wanting tidy aero upgrades, the Yokomo B7-GW40A Good Luck Wing Ver. 4.0 is a practical pick. Kojiro Unno's design aims to generate steady rear downforce using a precise and symmetric profile.
The B7-GW40A targets reliable downforce while retaining straight line stability. Its contours are the product of track work intended to keep tyre contact and control through fast turns.
This wing works with several Yokomo touring chassis lines, notably the BD7, BD8, BD9 and BD10, giving flexibility across different car builds.
