Product Description

The H&R 23037-4 is a VTF (Verstellbar TieferlegungsFedern) height-adjustable lowering spring set engineered specifically for the 2025+ BMW M5 Touring G99. Developed and tested on the Nurburgring, the VTF system delivers coilover-style ride height adjustability using precision collars and spring perches that allow stepless tuning within the approved range -- 25-35mm front and 20-30mm rear -- without modifying or compromising the factory electronic damper control system.

Manufactured in Germany from 54SiCr6 high-tensile spring steel, the progressive-rate springs lower the M5 Touring's center of gravity for flatter cornering, quicker turn-in, and reduced body roll while preserving the refined ride quality expected from BMW's flagship performance wagon. The VTF design retains full adaptive damper functionality, meaning comfort, sport, and sport+ modes all operate as intended at any selected ride height. TUV approved with parts certificate for road-legal use. M5 Sedan G90 owners should reference 23037-1 or 23037-3.
