Renew the rear torsion-bar mount on your classic Porsche 356 with this premium adjustable, zinc-plated, closed-type spring plate. Designed for models from the Pre-A era through 356 A and 356 B. The plated finish ensures long-term corrosion resistance, while the closed-type design offers improved durability and cleaner appearance. With its adjustable indexing feature, you can set ride height or corner balance precisely — ideal for restoration, spirited driving or show-quality builds.

What This Product Does:
- In a torsion bar suspension, the torsion bars provide springing by twisting under load, and the spring plate is the mount that anchors and supports the torsion bar end, controls ride height, and maintains alignment of the bar mounting.
- An adjustable spring plate allows for ride-height or corner-balancing changes by indexing or re-positioning the torsion bar mount. The “closed type” design improves durability and sealing of the mounting area.
- The zinc plating adds rust/corrosion protection, especially important in older cars with exposed suspension components.
- By maintaining correct mount geometry, the spring plate ensures that the torsion bar works within its intended range, the rear axle remains located correctly, and the chassis retains its handling characteristics.
Symptoms & Signs Of Wear Or Needing Replacement:
- Ride height is inconsistent or cannot be set accurately — e.g., rear is lower or higher than specification, even after index adjustment.
- Rear axle movement, clunks or knocks from the rear suspension when the car is driven over bumps — indicating play in the torsion bar mount or plate.
- The torsion bar mount area shows visible corrosion, fatigue, or deformation of the plate or its mountings.
- Suspension geometry (camber, toe) drifting under load or cornering — because the torsion bar mounting is loose or shifting.
- Difficulty in re-indexing torsion bars or keeping ride height consistent. The adjustable feature may be worn or seized.
Why Replacement / Upgrade Matters:
- On early 356 cars these parts are old and often have corrosion, fatigue, or alignment issues from decades of use and environmental exposure. Replacing the spring plate restores structural integrity.
- An Adjustable + Zinc-Plated + Closed type unit offers several advantages:
- Adjustable for ride height or corner balancing if you’re restoring or modifying the car.
- Zinc plating for corrosion protection extends lifespan.
- Closed type design better seals the mount area, prevents debris ingress and offers improved durability.
- Correct ride height and suspension geometry are critical for handling and tyre lifespan — a compromised spring plate undermines these.
- For restoration projects, retaining or improving original design intent with quality parts is essential for driving feel and value.

Porsche Suspension & Axle Parts
Porsche suspension systems are engineered with precision to deliver sharp handling, ride comfort, and maximum performance. Whether on the road or track, your Porsche relies on a finely tuned suspension and axle setup to keep you in control. When components wear out, the ride becomes rough, handling suffers, and safety can be compromised.
At Design911, we supply a full range of suspension and axle parts for classic and modern Porsche models — from shock absorbers and coil springs to control arms and ball joints - helping you maintain your car’s legendary driving dynamics.
Signs of Worn Shocks or Struts
Shock absorbers and struts are essential for keeping your
Porsche stable over bumps and through corners. Some signs they may need
replacement include:
- Excessive
Bouncing – car continues to bounce after hitting bumps
- Poor
Cornering Stability – leaning hard into corners, reduced grip
- Fluid
Leaks – damp or oily patches on shocks/struts
- Uneven Tyre Wear – poor damping leads to increased tyre wear
If left unchecked, worn shocks or struts not only reduce ride comfort but can also compromise safety.
Common Porsche Suspension Issues
Different Porsche models can face specific
suspension-related faults. The most frequent include:
- Lower
Track Control Arm Bushings - Failure
causes squeaking noises, uneven tyre wear, and eventually knocking sounds
over rough roads.
- Broken
Coil Springs - Seen
in models such as the Porsche Boxster. Symptoms include groaning noises
when steering and clicking or knocking over bumpy surfaces.
- Leaking
or Worn Shock Absorbers - Identified
by damp, oily residue on the shock body. This is one of the most common
suspension failures over time.
- Ball Joint Wear - Worn joints reduce steering precision and can lead to loss of control if ignored.
Fortunately, most of these issues can be resolved by simply replacing the affected parts with OEM or high-quality aftermarket components.
