What This Product Does:
- In a torsion-bar rear suspension setup, the torsion bar acts as the spring. The spring plate is the component that anchors the torsion bar end, holds it in position, and transmits spring loads into the chassis or subframe.
- The adjustable plate allows the torsion bar mounting point’s position or preload to be varied, giving control over ride height and corner balancing without needing major suspension changes.
- Because this version is zinc-plated, it offers improved corrosion resistance compared to untreated plates—helpful given the age of many 356-series cars.
- The “opened type” design, while more exposed, may simplify access for inspection or adjustment, and may reduce the weight or complexity of the cover.
- Overall, the spring plate ensures correct geometry of the rear suspension, maintains consistent ride height, and ensures the torsion bar works within its intended range.
Symptoms & Signs It Might Need Replacement/Upgrade:
- Rear ride height is low, uneven, or difficult to set accurately; the car sits differently on one side or the rear sags.
- Clunking or knocking noises from the rear when going over bumps, especially if the torsion-bar end is shifting in its mount.
- Rear suspension geometry drifting under load — tyres showing unusual wear, or rear end feeling less stable in corners.
- Visible corrosion, fatigue, deformation or play in the spring plate or its mountings; the zinc plating may be pitted, or the plate may be weakened.
- If you’re restoring the car, or have modified the suspension (lowering ride height, wider tyres, upgraded rails), you might need the adjustable feature of the new plate for proper setup.
Why Replacement / Upgrade Matters:
- Given the age of many Porsche 356 C cars, original spring plates may have corrosion, fatigue, or mis-alignment — replacing with a high-quality zinc-plated adjustable type helps restore structural integrity.
- The adjustable function gives flexibility for ride-height tuning and corner balancing, which is especially beneficial when restoring, upgrading, or converting to performance use.
- The zinc-plated finish improves resistance to rust and environmental wear, which contributes to longevity and maintenance-free performance.
- Using a correctly specified spring plate ensures the torsion bar mount behaves as intended, keeps geometry intact, and allows the rear suspension to function with precision. This means better handling, consistent ride height, fewer alignment issues, and longer lasting components.
- In summary, upgrading this small but essential part is a foundational move in a restoration or performance refresh of a classic Porsche torsion-bar rear suspension.
