Dinan Front Lower Control Arm Kit - 2012-18 BMW 3/4 Series incl. 340i/440i (F3X)

The front thrust arms on the F30 and F32 hold the wheel through soft rubber bushings, and that rubber flexes every time you turn in or brake hard. Dinan's Monoball kit swaps those bushings for precision ball joints, so the front end reacts to the wheel more directly and brake shimmy is reduced.

What you get

• Precision ball joints in machined aluminum housings in place of the factory rubber thrust-arm bushings.
• Nylon-lined bearings, which Dinan says are close to silent, so the kit is livable on a daily driver.
• Sealed with rubber boots to keep road dirt out and stop early wear.
• Sharper steering response and less brake shimmy, according to Dinan.

Good to know

• Dinan lists this kit as not compatible with xDrive cars.
