NM Engineering's RS Alpha progressive rate spring kits provide a responsive ride, sharper handling characteristics and lowered ride height. Using exacting spring rates and precision manufacturing techniques, RSa springs provide a more pleasurable motoring experience.

Fits the following models:

2014-2022 F56 MINI Cooper and Cooper S Hardtop
2015-2022 F55 MINI Cooper and Cooper S Hardtop 4-Door
2016-2022 F57 MINI Cooper and Cooper S Convertible

NOTES:

• The rear on the F55 4-Door may sit a few millimeters lower compared to the F56 with these springs, but that will be barely noticeable and will make the car sit more 'level'.
• Compatible with standard or sport suspension.
• These springs were developed and tested on a model with the Dynamic Damper Control (DDC), so yes - they are compatible.

Lowering Rate:

B46/48 (2.0T)
Front: 33mm (1.30")
Rear: 31mm (1.22")

NEGATIVE REAR CAMBER:

Lowering the ride height will add negative camber to the rear. For best results, you should add adjustable rear control arms to correct the rear camber after lowering your car. If you choose not to correct the rear camber, your rear tires will wear unevenly and may adversely affect handling. Install the rear adjustable control arms and have the alignment corrected.

You can find Adjustable Rear Control Arms here.
