Neuspeed NM Eng. RS Alpha Springs Kit For F55/56/57 - NM.558846

Transform your MINI’s driving dynamics with the Neuspeed NM Engineering RS Alpha (RSa) Progressive Rate Springs Kit, engineered for the F55, F56, and F57 chassis. Designed to enhance handling performance while maintaining everyday comfort, this spring kit provides a noticeable reduction in ride height, improved suspension response, and a more aggressive stance—all without compromising ride quality.

Constructed with precision manufacturing techniques and built from high-grade spring steel, NM RSa springs feature a progressive spring rate that balances comfort during normal driving with increased stiffness under hard cornering. The result is sharper steering response, reduced body roll, and improved confidence behind the wheel. Each set is finished in a durable NM Blue powder coat, ensuring corrosion resistance and long-term visual appeal.

Whether you're carving corners or cruising city streets, the RS Alpha Springs Kit delivers the perfect blend of performance and style.
