Bilstein B12 Handling Package for BMW 3 Series E46 330d and 330Cd

Part number: BILSTEIN-46-180025

Give your E46 diesel a serious chassis upgrade with this proven shocks and springs package. The Bilstein B12 kit partners shortened Bilstein B8 sport dampers with Eibach Pro-Kit progressive springs to deliver sharper responses, flatter cornering and a purposeful ride height drop while keeping day-to-day comfort intact. Expect confident turn-in, tighter body control and a stance that looks right on the road.
