Why it works on the BMW X1 E84

• Matched components - Bilstein B8 short-stroke dampers paired with Eibach Pro-Kit springs for balanced control
• Typical lowering of around 10-30 mm depending on engine and spec for a purposeful look and better aerodynamics
• Monotube gas pressure technology for consistent damping and fade-free performance
• Sharper turn-in and reduced pitch and roll without a harsh ride
• German TÜV approved quality and durability
• Direct replacement using OE-style mounts to keep installation straightforward

We run B12 kits on our own builds and customer cars. Feedback is overwhelmingly positive, with drivers praising the improved precision, confidence in quick direction changes and the composed ride on poor road surfaces.

What you get in the box

• 4 x Bilstein B8 sport shock absorbers
• 4 x Eibach Pro-Kit progressive lowering springs

This is a fixed-height sports suspension kit. It is not height adjustable, which makes it a brilliant road-focused alternative to coilovers if you want a well-judged drop with OEM-plus comfort.

Key tech highlights

• Bilstein monotube construction for precise damping control
• Gas pressure system maintains performance under hard use
• Progressive spring rates provide compliance over small bumps and control under load
• Optimised pairing of spring and damper for balanced fast-road dynamics

Lowering range

Approximate drop of 10-30 mm depending on model. Actual results vary by vehicle. A four-wheel alignment is recommended after fitting.
