Upgrade Rear Traction on Your BD9 Chassis

Will this arm help understeer on low grip tracks?

Yes, adding rear compliance with the B9-008RA can reduce mid-corner understeer by allowing the rear to better follow the track surface.

Should I change shock settings after fitting?

Minor shock adjustments are often useful; try softening rebound or lowering damping to match the arm's increased flex.

Is it a direct replacement for the stock arm?

Yes, it replaces the stock rear arm using the same mounting points, so installation is straightforward on compatible chassis.

Any maintenance tips for longevity?

Keep pivot holes free of grit, and avoid overtightening fasteners. Regular checks after sessions will extend service life.

Will this affect front to rear balance significantly?

The change is subtle and focused on rear traction. Expect a shift toward a more planted rear feel rather than a wholesale balance overhaul.
