Product Details

The Whiteline Heavy Duty Blade Adjustable 16mm Rear Sway Bar fits the 2011-2012 Mazda MX-5 Miata Special Edition (NC). Placement: rear. The part number is BMR81Z. Trim named on the listing: Special Edition. Included: 1 sway bar and 2 bushings. Application note: 3 Point Adjustable.

The rear sway bar has a large say in how a car balances. Stiffening it limits roll at the back and brings the tail around more readily, which many drivers use to lessen understeer and sharpen response. Adjustable mounting points let you step the stiffness up or down without changing the bar.

Installation is rated moderate, with about 1 hour of work listed. A wheel alignment is not required. Other Whiteline parts we list for the MX-5 Miata: Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front Control Arm Lower Inner Front Bushing.

Features

  • Bushing compound: Bushings made of a low-compliance elastomer cut flex and movement in the suspension.
  • Bar mounts: The mounts have an internal bore pattern and lips that retain grease.
  • Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
  • Hardware: Hardware supplied: mounting brackets.
  • Roll control: Built to reduce lean when cornering.
  • Install guide: Written install instructions are included with the part.
