The H&R adjustable sway bar kit for 2021-and-up Subaru BRZ pairs a 22mm front bar with an 18mm rear bar specified for the BRZ chassis. This direct-fit kit replaces the stock anti-roll bars to let owners tune front and rear roll stiffness independently, helping refine handling balance and body control while fitting 2021+ BRZ suspension mounting points.
