Aerodynamic Enhancements with Yokomo B7-GW40SDA

For serious tuning work, the Yokomo B7-GW40SDA side dams provide a reliable way to manage airflow at the rear of the car. Specifically designed for the Good Luck Wing Ver.4.0, they help keep the chassis stable when entering and exiting fast sections.

Compatibility with Established Chassis

The Yokomo B7-GW40SDA has broad compatibility across Yokomo platforms, making it useful for a range of builds. Installers often fit them to MRTC-BD7 variations and later MRTC-BD12 cars, but confirm the wing mounting pattern on your machine.

Practical Tuning Notes

By smoothing airflow and adding consistent downforce, these side dams reduce high speed instability and make car behaviour more predictable. Installation is uncomplicated and they suit both experienced tuners and those developing their setup skills.
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.

Do these side dams fit all Good Luck Wing Ver.4.0 wings?

They are made for the Ver.4.0 profile, but you should inspect your wing's mounting holes to ensure a correct match before attempting to fit.

What sort of track gains can I expect?

Expect increased rear stability and reduced twitchiness at higher speed; this makes the car easier to place through rapid corners and fast chicanes.

How robust are the side dams in traffic?

They are simple aerodynamic fittings and tolerate normal contact, but you should check fixings after impacts and replace any damaged parts to retain aero balance.
