Reinforced Rear Suspension – Fiat 600

Rear Control Arms and Coilover Shock Absorbers

This set of rear control arms, pantograph links, and coilover shock absorbers has been developed specifically for the Fiat 600, with the goal of modernizing and reinforcing the rear suspension, significantly improving stability, control, and overall dynamic response compared to the original system.

Designed for sport street use, track days, hill climb, and optimized vintage projects, this setup brings the rear axle behavior to a much higher level while maintaining predictable, adjustable, and reliable performance.


Adjustable Geometry and Alignment

This kit allows full rear suspension alignment, enabling precise adjustment of:

  • Toe (convergence / divergence)

  • Camber

  • Track width

  • Overall rear axle alignment

Adjustments are performed after setting ride height, using a three-thread adjustable plate located on the wheel side, to which the hub and bearing carrier are mounted. This solution allows accurate, repeatable setup and fine tuning for performance-oriented applications.


Adjustable Coilover Shock Absorbers

The included coilover shock absorbers allow:

  • Fine ride height adjustment

  • Precise corner weight balancing

  • Quick spring rate changes

  • Fast and practical assembly for setup changes

An ideal solution for drivers and builders seeking better chassis balance without unnecessary complexity.
