H&R Lowering Springs for BMW 4 Series G22 G23 G26 Cabrio Gran Coupé FA40/RA25mm

Manufactured from high-grade steel at H&R's facility in Germany, each spring is powder coated to resist corrosion and maintain a clean appearance under the car. H&R designs these springs to work directly with your factory shock absorbers — including BMW's adaptive suspension and M-suspension setups — so there is no need to replace your dampers to run this kit. Compatibility with quality aftermarket dampers is also confirmed, giving you a clear upgrade path if you choose to go further.

On the road, the lower center of gravity translates to tighter turn-in, reduced body roll, and a more planted feel through corners — tangible improvements you notice on the first drive. The spring rate is calibrated to preserve everyday ride quality, meaning the G23 Cabrio remains comfortable over real-world road surfaces while looking and handling significantly better than stock. This is not a compromise; it is exactly the balance a daily-driven BMW enthusiast needs.

Every H&R kit ships with ABE or TÜV approval documentation, confirming full compliance with German and European road regulations. This is particularly important for G23 Cabrio owners given the additional structural considerations of a convertible chassis — H&R's engineering accounts for that. If you want a suspension upgrade backed by decades of German precision and certified for legal road use, this is the definitive choice for your 4 Series.
