OVERVIEW
Drivers familiar with chassis tuning on modern MINI platforms know that a sway bar upgrade is one of the most effective ways to sharpen handling, and the NM Engineering GT Sway Bar delivers exactly that. Designed specifically for the MINI Gen2 F55/F56/F57 and Gen3 F65/F66/F67 chassis, this bar significantly reduces body roll while improving steering response, balance, and overall driver confidence.
On these MINIs, the 25mm Sway Bar enhances cornering stability in a way that rivals — and in some cases exceeds — the perceived benefit of lowering springs or coilovers alone. The result is a more planted feel through corners, improved rotation, and a chassis that remains predictable and composed under aggressive driving conditions.
Engineered to work seamlessly with the factory suspension geometry, the NM Engineering 25mm Sway Bar provides a clear performance advantage for spirited street driving, canyon roads, and occasional track use — all without compromising daily drivability.
