Product Details

Bilstein B12 (Pro-Kit) suspension kits are built as a coordinated package rather than a mix-and-match setup. For the Mazda MX-5 Miata, the dampers and springs are selected to work together at a fixed ride height, helping maintain balanced suspension behavior while lowering the vehicle for a more controlled stance. The monotube damper construction supports consistent damping performance, and the B12 (Pro-Kit) line focuses on a practical blend of suspension dynamics, quality, and appearance. If you are searching for a Bilstein MX-5 Miata suspension kit or Bilstein 46-190345 for 2006-2015 Mazda MX-5 Miata, this kit matches that application.

The B12 (Pro-Kit) line is Bilstein’s fixed-height lowering solution paired with Eibach springs. It is aimed at drivers who want a moderate drop without changing to an adjustable coilover system. This part cross-references Eibach E90-55-010-01-22 for the same application.

Common Issues This Kit Can Address

  • Excessive factory ride height on a Mazda MX-5 Miata
  • Worn dampers that reduce suspension control
  • Uneven handling balance between front and rear
  • Body roll during cornering
  • Need for a matched lowering spring and damper package
