H&R BMW M3/M4 Competition xDrive G80 (AWD) Sway Bar Kit - 30mm Front/27mm Rear

H&R's sway bar kit for the AWD M3 and M4 Competition replaces both the front and rear bars to reduce how much the car leans in turns. Unlike lowering springs, it doesn't change ride height or ride comfort, just how the car holds itself through a corner.

What you get

• 30 mm front and 27 mm rear bars as a matched pair.
• Stiffer roll resistance for more grip and stability side to side.
• Forged, clean-finished bar ends, which on certain models offer adjustable stiffness.
• Squeak-free urethane and Teflon bushings that need no lubrication.

Good to know

• Listed for xDrive (AWD) cars.
