Product Details

Lowering a 2003-2008 BMW Z4 with mismatched parts is how you end up with a car that crashes and skips. The Bilstein B12 kit pairs the springs and dampers as a designed set.

The monotube design is what sets Bilstein apart. A single high-pressure gas chamber keeps the oil from aerating, so the damping stays consistent on a rough road instead of fading as the unit heats up.

Features

  • Precise response, excellent driving dynamics and high reserves of safety
  • Offers even lowering between 25-40mm, depending on application
  • Eibach Pro-Kit performance suspension spring with progressive characteristics
