Key Features

• Bilstein Performance dampers paired with Eibach Pro-Kit springs
• Moderate lowering range of 24-40 mm, depending on application
• Application-specific tuning for fixed ride height and balanced suspension response

• Yellow dampers with dark grey springs
• Part number 46-278692 for direct catalog reference

Product Line Details

The Bilstein B12 (Pro-Kit) line is aimed at drivers who want a matched damper-and-spring solution rather than mixing components from different setups. For the Mazda MX-5 Miata and Fiat 124 Spider, the spring and damper rates are selected to work together for lowered ride height, improved suspension dynamics, and a more refined appearance without changing the vehicle into an extreme drop setup. If you are searching for Bilstein 46-278692 for a Mazda MX-5 Miata suspension kit or a Fiat 124 Spider lowering kit, this is the application-specific option in the B12 (Pro-Kit) series.

What This Suspension Kit Helps Address

• Excessive body movement during cornering and braking

• Need for a fixed-height lowering solution for the MX-5 Miata or 124 Spider

Installation Notes and Tips

Install Bilstein 46-278692 as a complete suspension upgrade on the specified front and rear positions only. Verify axle load and rear lowering notes before installation, especially on the Mazda MX-5 Miata and Fiat 124 Spider applications. Because this kit uses matched dampers and springs, final ride height and handling balance depend on the vehicle configuration and the listed fitment notes.

Quality Assurance

Bilstein uses a monotube damper design in this B12 (Pro-Kit) suspension kit to support consistent damping characteristics across the application. The components are engineered as a matched system for the listed vehicles, and the part number 46-278692 is the correct catalog reference for ordering and fitment verification.
