Improve Rear Grip on Asphalt for Your BD9

The Yokomo B9-008RA Rear Suspension Arm is engineered for the BD9 and built from a softer resin than the usual graphite blend. That additional compliance helps the rear tyres maintain contact on low grip asphalt, which improves cornering predictability during fast laps.

Fitment and Versatility

This rear arm fits a number of related chassis platforms, offering a straightforward upgrade path for drivers looking to trade a bit of stiffness for better rear traction.

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.

Does the B9-008RA affect roll centre or geometry?

The part maintains the original mounting points, so geometry stays the same; the handling change comes from material flex rather than altered geometry.

Is it compatible with aftermarket uprights?

Compatibility depends on the upright design, but it works with most stock-style uprights used on the listed chassis. Check fitment before final assembly.

How should I inspect the arm after racing?

Look for signs of deformation around mounts and for play at pivots. Replace if you notice excessive wear or cracking to keep handling consistent.

Will this arm change tyre wear patterns?

You may see more even rear tyre loading, which can alter wear slightly. Track tyre condition and adjust camber or toe as needed.
