Overview

The NM Engineering GT Sway Bar is a rear 25mm anti-sway bar designed to reduce body roll and improve handling on specific MINI models. It enhances cornering stability, steering response, and overall driver confidence.
Show original supplier description
The NM Engineering GT Sway Bar is specifically engineered for the MINI Gen2 F55/F56/F57 and Gen3 F65/F66/F67 chassis. This 25mm rear anti-sway bar significantly reduces body roll, leading to improved steering response, better balance, and increased driver confidence. Constructed from mandrel-bent chromoly heavy-wall tubing for consistent diameter and precise torsional response, this bar offers increased rigidity. It features forged end sections with two adjustable mounting points and billet 7075-T6 aerospace-grade aluminum sway bar clamps. The bushings are made from graphite-impregnated urethane for durability and smooth operation, and the bar has a gloss blue powder-coat finish. With 3-way adjustability, you can fine-tune the handling balance. NM Engineering strongly recommends their Rear Sway Bar Link Kit for optimal performance and durability when installing this sway bar. It is designed and engineered in Camarillo, California, and made in the USA.
