Bilstein B12 Pro-Kit Suspension Kit (B8 Dampers + Eibach Springs) for BMW 3 Series Touring G21/G81 2019+ | 1030mm Lowering | Fixed-Height | Part 46-322319

Bilstein B12 Pro-Kit for BMW 3 Series Estate G21 and G81 | Part 46-322319

Looking to sharpen your BMW 3 Series Touring without ruining daily comfort on UK roads? This Bilstein B12 Pro-Kit pairs uprated B8 gas-pressure shock absorbers with Eibach Pro-Kit progressive springs for a confident fast-road setup, tighter body control and a purposeful stance. Expect a ride height reduction of roughly 10 to 30 mm depending on model specification, delivering flatter cornering, crisper steering response and reliable stability at speed.

This is an engineered spring and damper package that just works. We have run this kit on our own cars and fitted it for customers across the country; feedback is consistently positive for its blend of composure, grip and everyday usability. If you want a non-adjustable, fit-and-forget performance upgrade for your G21 or G81 estate, this is the benchmark.

Why this upgrade stands out

• Matched B8 dampers and Eibach progressive-rate springs for balanced fast-road dynamics
• Lower centre of gravity by approximately 10 to 30 mm for reduced body roll and improved turn-in
• Monotube gas-pressure technology for consistent damping and fade-resistant control
• Predictable, confidence-inspiring behaviour on British B-roads and motorways
• TUV approved components with renowned Bilstein durability
• Fixed ride height solution for those who do not need height adjustment

What is included

• 4 x Bilstein B8 performance shock absorbers
• 4 x Eibach Pro-Kit progressive springs
• Application-specific fitment components as required by the manufacturer
