Sports Quick Adjust Rear Spring Plate Set. Porsche 911 1986-89 (With G50 Gearbox)
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1978-1989 3.3L Turbo (930)
Upgrade your Porsche 911’s rear torsion-bar mounting with this Sports Quick-Adjust Rear Spring Plate Set. Ideal for 1987-89 G50 911 and 1989 Turbo models, this set replaces the original fixed plates with indexed, adjustable units featuring performance-grade bushings and high-strength steel plate. The adjustment mechanism allows ride-height and preload tuning without full disassembly, while the upgraded construction gives firmer, more consistent rear-end behaviour under load. Suitable for restoration, lowered or track-use applications, this direct-fit set ensures your rear suspension mounts operate at a higher standard.
Sold As A Set.
Fits:
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1978-1989 3.3L Turbo (930)

What This Product Does:
- On this generation of Porsche 911 with rear torsion-bar suspension, the spring plate is the component that anchors the torsion bar end to the chassis/axle assembly. It controls ride height, torsion bar preload, and helps maintain correct rear-axle geometry (camber, toe, etc.).
- The adjustable variant adds an indexing mechanism so you can adjust ride-height or preload without full disassembly—useful when lowered, stiffened, or track-modified.
- “Sports” grade implies upgraded materials (e.g., higher hardness rubber, improved steel plate) to reduce unwanted flex and improve rear-end stability under load.
Symptoms & Signs Of Wear Or When To Upgrade:
- Rear ride-height is inconsistent or one side sits lower/higher than the other.
- The rear suspension feels loose, vague or “floating” in corners — especially under hard acceleration/braking.
- Uneven or excessive rear tyre wear (inner/outer shoulder) indicating geometry is shifting under load.
- The car has been modified (lowered, stiffened springs, wider tyres) and original non-adjustable plates limit setup or ride-height tuning.
- Visual inspection: the original plate is rusted, bushings are cracked/collapsed, the indexing mechanism is worn or non-existent.
Why This Upgrade Matters:
- Improves rear suspension precision: The adjustable plate ensures the torsion bar end is mounted with correct preload and ride-height, which helps maintain alignment under dynamic load, improving handling and tyre life.
- Facilitates tuning and setup: Especially for lowered or performance cars, the quick-adjust mechanism makes repeated setup/ride-height changes easier.
- Restores structural integrity: Original plates may have aged, corroded or lost their adjustability; upgrading renews this key mount.
- Maximises benefit of other upgrades: If you’ve upgraded torsion bars, springs, shocks, ensuring the spring plate is performance-spec ensures nothing in the rear mount is the weak link.

Porsche Spring Plates | Design911 Suspension Components for Ride Height, Alignment & Stability
Spring plates are a critical part of your Porsche’s rear suspension system, connecting the torsion bars to the trailing arms and helping manage suspension travel and ride height. They act as pivot points that absorb energy during acceleration, braking, and cornering — ensuring smooth movement and maintaining chassis balance. Properly functioning spring plates preserve suspension geometry, enhance grip, and provide the responsive handling Porsche is known for.
At Design911, we supply a complete range of spring plates and components, engineered for precision, strength, and long-lasting performance. Manufactured from high-quality steel or performance-grade alloys, our spring plates deliver exact fitment and reliable operation under all driving conditions. Ideal for servicing, classic restorations, or performance tuning, they help maintain stability, comfort, and control across your Porsche’s suspension system.
What Do Spring Plates Do?
Spring plates play a vital role in controlling the movement and alignment of the rear suspension, ensuring even weight distribution and consistent handling.
Core Functions:
• Connect torsion bars to trailing arms for proper suspension movement.
• Regulate ride height and suspension travel.
• Maintain consistent rear wheel alignment under load.
• Absorb road impact to enhance ride comfort and grip.
• Provide smooth suspension articulation for balanced handling.
In perfect condition, spring plates ensure your Porsche remains stable, comfortable, and responsive — on both the road and track.
Why Do Spring Plates Fail or Degrade?
Due to constant movement, load stress, and environmental exposure, spring plates are subject to wear and corrosion over time.
Common Causes of Failure Include:
• Corrosion or rust weakening the plate material.
• Worn bushes or mounts causing excess play and vibration.
• Fatigue cracks from continuous torsional stress.
• Impact damage from potholes or aggressive driving.
• Incorrect alignment or ride height adjustments.
When spring plates fail, you may notice uneven ride height, poor alignment, or rear-end instability — clear signs that replacement is needed to restore balance and safety.
Why Replace or Upgrade Your Porsche Spring Plates?
Replacing worn or damaged spring plates restores suspension geometry, alignment accuracy, and overall handling performance. Upgraded plates offer improved adjustability and durability — ideal for performance builds or track preparation.
