Bilstein B12 Sportline Suspension Kit 46-313331 for BMW 3 Series G20 (2019+) - Lowering Springs & Dampers | Non-EDC (Non-Adaptive) | Fits 318i 320i 330i 316d 318d 320d 320e PHEV

Bilstein B12 Sportline Shock and Spring Set - Part No. 46-313331

Give your BMW 3 Series G20 the stance and road holding it deserves with the Bilstein B12 Sportline shock absorber and coil spring package. This matched damper and spring bundle delivers crisper turn-in, tighter body control and a confident, planted feel on fast A-roads and B-roads while remaining comfortable for daily use. If you want a meaningful drop in ride height, sharper steering response and predictable grip without going to coilovers, this is the proven street performance solution.

We have fitted this kit for local owners and feedback has been consistently excellent on ride quality, cornering stability and the purposeful look once installed. Customers love the improved balance and the way the car settles into a corner, with less pitch under braking and reduced squat on acceleration.
