Rear Stabilizer Bar LA422-16 for SB ZX7.5 RB7.5 - Kyosho  [KY-LA422-16]

Tuning effects on corner balance

The Kyosho LA422-16 rear stabilizer bar is a direct-fit option for SB, ZX7.5, and RB7.5 chassis where the number applies. As a rear sway bar it is used to control chassis roll and to shift handling bias as part of a broader setup strategy focused on lap time improvements.

Install the bar into the stock rear stabilizer mounts and retain standard hardware unless inspection reveals worn parts. The swap is straightforward, but verify free rotation and full suspension travel clearance before testing at speed.

In tuning practice, stiffening the rear bar reduces roll and can induce understeer, while softening it increases rear grip sensitivity and can promote oversteer depending on front settings. Change one variable at a time and log lap-by-lap differences to assess the impact accurately.
