Overview

Bilstein B12 (Pro-Kit) suspension kit 46-190338 combines matched dampers and springs for a fixed-height lowering setup. It is tuned for the Mazda RX-8 and delivers a balanced change in stance and suspension response without mixing unrelated components.

Key Features

  • Bilstein Performance dampers paired with Eibach Pro-Kit springs
  • Moderate lowering range of 24-40 mm, depending on application
  • Monotube internal design for consistent damping control
  • Yellow dampers with dark grey springs
  • Application-specific tuning for fixed-height lowering

Detailed Description

The Bilstein B12 (Pro-Kit) line is built as a matched suspension package rather than a collection of separate parts. For the Mazda RX-8, part number 46-190338 uses Bilstein dampers and Eibach springs that are tuned together to deliver a controlled lowering result and a more settled suspension setup. This kit is intended for drivers who want a direct suspension upgrade with a defined ride height change and coordinated damping characteristics.

Bilstein B12 (Pro-Kit) suspension kits focus on application-specific tuning, which helps maintain predictable suspension behavior after lowering. The monotube damper design supports consistent response, while the spring package provides the lowered stance associated with the B12 (Pro-Kit) series. Part number 46-190338 is also cross-referenced to E90-55-007-01-22 for the same application.

What It Is Used For

  • Replacing worn suspension components with a matched kit
  • Lowering ride height in a controlled, fixed-height setup
  • Improving suspension balance after a spring and damper upgrade
  • Restoring more consistent damping response
  • Reducing the mismatch that can occur when springs and dampers are selected separately

Installation Notes

Compatible with 2004-2011 Mazda RX-8, front and rear. Rear lowered height is listed at 25 mm, with up to 1030 kg axle load noted for the application. Verify vehicle configuration and suspension condition before installation. Professional installation and a post-installation alignment are recommended after any suspension height change.

Quality Assurance

Bilstein B12 (Pro-Kit) suspension kits are built around matched components and application-specific tuning for the listed fitment. Bilstein part number 46-190338 is engineered as a fixed-height lowering solution for the Mazda RX-8 platform.
