Whether installed on a MINI Clubman or Countryman, or a BMW X1 or X2, the GT Sway Bar enhances cornering stability and responsiveness in a way that rivals, and in some cases exceeds, the benefits of lowering springs or coilovers alone. The result is a more planted rear end, improved rotation through corners, and a chassis that feels tighter and more predictable under load.

Crafted with a mandrel-bent chromoly heavy-wall tube, the NM Eng Anti Sway Bar ensures consistent diameter for precise torsion motion. Its forged ends with two adjustment mounting holes, billet 7075-T6 aerospace-grade sway bar bracket, 90° Zerk fitting for easy re-greasing, and graphite impregnated urethane bushing ensure durability and performance. The glossy blue powder-coat finish and 3-way adjustable preload make it ideal for aggressive urban driving, canyon carving, and track/autocross use.

Please note: The NM Engineering Sway Bar Link kit is recommended for optimal performance when used with the GT Sway Bar.

  • Improved body roll management
  • Enhanced handling and steering input
  • Ideal for aggressive urban driving, canyon carving, and track/autocross applications
  • Durable construction for long-term use
