Fine-Tune Aerodynamics with Yokomo B7-GW40SDA

If race day calls for cleaner rear grip, the Yokomo B7-GW40SDA side dams add controlled airflow management to the Good Luck Wing Ver.4.0. They help the car stay composed when running at high speed.

Chassis Compatibility Overview

The Yokomo B7-GW40SDA will integrate with a variety of Yokomo platforms, providing flexibility for different builds. Common pairings include MRTC-BD7 based layouts and later MRTC-BD12 designs, though you should confirm mount alignment before fitting.

Performance Impact and Practical Use

These side dams reduce turbulent air around the wing, increasing rear downforce for steadier handling. They are easy to fit and make a useful tuning option for drivers refining balance for competition or club meetings.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which Yokomo cars are best matched to these side dams?

They are suited to a range of Yokomo chassis, commonly used on MRTC-BD7 and MRTC-BD12 types. Always check the wing and mount interface on your car.

Will they affect lap times or just feel?

The main effect is improved stability and predictability, which can translate into faster lap times once the driver adapts setup and driving lines.

Can I tune the effect after fitting?

Tuning options are limited to minor wing angle and mounting changes; the dams themselves deliver passive aero gains without adjustable parts.

Are these suitable for beginners?

Yes, because installation is simple and the performance effect is immediate, they are a good entry-level aero upgrade for newcomers.
