What This Product Does:
- The spring plate is the point where the torsion bar is mounted into the chassis — it transfers torsional force (spring action) from the torsion bar to the body / suspension.
- The adjustability allows you to change how much preload (twist) is put on the torsion bar, which influences ride height, spring rate, and camber under load. This is especially beneficial for performance tuning or if you have modified suspension, tires, or body geometry.
- With an adjustable plate, you can fine-tune corner balance, handling traits, and compensate for wear or changes in suspension parts over time.
- Also, replacing old, rusty, or fatigued plates with fresh adjustable ones restores rigidity, consistency, and accuracy to the rear suspension geometry
Symptoms & Signs You May Need Replacement:
- The original plates are rusty, corroded, or weakened (common in older cars)
- The car’s rear ride height or camber is out of spec, and you need a way to adjust without drastic modifications.
- You notice uneven tire wear, or inconsistent handling from side to side, which can be improved by more precise geometry control.
- Upgrading to adjustable rear spring plates gives you complete control over your Porsche’s suspension setup. Factory plates offer no fine adjustment, making it difficult to achieve precise ride height, camber, and corner balance — especially on modified or track-driven cars.
- With this adjustable design, you can easily tune torsion bar preload and suspension geometry, ensuring the perfect stance and balance for your driving style. The result is sharper turn-in, improved rear-end grip, and more predictable handling, whether on the road or at the circuit.
- For classic Porsche models using torsion-bar suspension, this upgrade transforms the driving experience — combining modern adjustability with quality fitment and long-term reliability.

Rear Spring Plates, SET OF 2.
Porsche 964
Porsche 993
This kit replaces the factory spring plates and compliant rubber bushings with a precision rod end that allows for friction free movement and easy adjustment of toe angles without affecting camber.
Please note original Porsche spring plates OE Numbers 96433106008 / 96433106010 are no longer available, so these are a great alternative.
The precision rod end also improves driver feedback and maintains alignment settings for better handling.
The plates are fabricated from alloy steel and nickel plated for strength and corrosion resistance.
Allows for camber settings up to -4.5 deg. Mount with slot on top for camber angle more than -1.5 deg.

Our bushing replacement kit allows you to restore your original spring plates, without the high cost of complete replacement plates. Our product is modeled after the factory original bushings and similarly includes a spherical bearing encased in an outer elastomeric layer. The elastomeric layer provides noise and vibration isolation, similar to the OEM components.
Our bushing replacement kit includes fully sealed monoball cartridges featuring maintenance free PTFE linings that require no lubrication. The cartridges are encased in an elastomeric layer that is slightly firmer than stock to improve performance, reducing deflection under load while maintaining the noise isolation characteristics of the original rubber. Weather seals keep dirt out and extend product life.
