BMW E8x E9x Rear 40 mm Drop Coil - Single piece - H&R 29183HA1

Part number: 29183HA1

Give your 1 Series or 3 Series the stance and road feel it deserves. This genuine H&R rear coil delivers an approximate 40 mm ride height reduction at the back axle, sharpening turn in, limiting squat and roll, and transforming confidence in fast corners while keeping everyday comfort intact. Precision engineered in Germany, TUV approved and powder coated for durability, it is the go-to rear suspension upgrade for E8x and E9x owners who want a purposeful, balanced look and a more connected drive.

We have installed this spring on our own builds and plenty of customer cars. Feedback has been consistently positive on stability, grip and aesthetics. It integrates perfectly with factory shock absorbers as well as quality performance dampers, making it a smart, value-packed way to achieve a tidy drop at the rear without compromising usability.

Highlights

• Approx 40 mm reduction at the rear for a level, squat-free stance
• Sport-focused spring rate with OEM-like refinement for daily use
• Lower centre of gravity for improved turn-in and mid-corner composure
• Works with stock dampers and most reputable aftermarket shocks
• Powder coated finish for corrosion resistance and long service life
• Made and tested in Germany with TUV certification
