Fits On To Diagram Ref No 25
What This Product Does:
- The spring plate is part of the torsion bar suspension system: as the rear suspension moves, the torsion bar twists, and the spring plate (with its bushings) transmits those torsional loads to the chassis.
- The bushings isolate vibration and reduce noise, and they allow some controlled movement, while preventing excessive play.
- A correctly functioning spring plate + bushing assembly helps maintain rear ride height, alignment consistency, and smooth articulation of the rear suspension under dynamic load.
- Clunking / knocking noise at the rear when driving over bumps or under load.
- Sagging or uneven ride height at the rear (one side lower)
- Excessive rear vibration or harshness under acceleration or load
- Contact / rubbing noise — the worn bushings may allow the spring plate to contact its cover or adjacent metal surfaces.
- Degraded handling / instability in the rear under cornering
- Loss of the “tight” feel in the rear suspension; more play in the rear suspension response
Why Replacement Matters:
- Restores Rear End Stability & Ride Quality: The upgraded, stiffer bushings reduce unwanted movement and maintain better control under load.
- Preserves Correct Geometry & Height: Keeps torsion bar and spring plate alignment tight, preventing sag or misalignment over time.
- Reduces Noise & Harshness: Eliminates metal-to-metal contact and vibration that results from deteriorated rubber.
- Better Durability: Heavy-duty rubber compound resists deformation, aging, heat, and oil.
- Protects Other Components: Reduces stress on torsion bars, suspension arms, and adjoining parts that might be damaged by excessive play.
- Essential for Restoration / Rebuilds: When rebuilding rear suspension or restoring a classic 911, these bushings are part of a full refresh to return the car to factory (or better) behavior.

Precision-machined for direct OE-style fitment, it restores the secure location of the spring plate and helps maintain consistent rear suspension performance.
What This Product Does:
- Secures the rear spring plate to the suspension mounting point.
- Maintains accurate rear suspension geometry.
- Reduces unwanted suspension movement and deflection.
- Improves handling precision and vehicle stability.
- Supports consistent wheel alignment.
- Helps optimise suspension response during acceleration, braking and cornering.
- Reduces excessive movement under load.
- Forms an essential part of the rear suspension system.
Symptoms Of Wear Or Failure:
- Knocking or clunking noises from the rear suspension.
- Excessive rear suspension movement.
- Poor handling or reduced cornering stability.
- Uneven or accelerated rear tyre wear.
- Rear wheel alignment drifting out of specification.
- Vague or inconsistent steering feel.
- Visible cracking, deformation or deterioration of the bushing.
- Rear suspension movement during braking or acceleration.
- Increased vibration transmitted through the chassis.
- MOT or vehicle inspection failure due to worn suspension bushes.
Why Replacement Matters:
- The spring plate bushing is subjected to continuous suspension movement, heavy cornering loads, braking forces and exposure to road debris, moisture and temperature fluctuations. Over time, the original bushing can wear, compress or deteriorate, allowing excessive movement within the rear suspension.
- A worn spring plate bushing can negatively affect wheel alignment, handling precision and tyre wear while placing additional strain on surrounding suspension components. Excessive movement may also reduce vehicle stability and driver confidence, particularly during spirited driving or high-speed cornering.
- Replacing a worn spring plate bushing restores the correct positioning of the rear suspension and improves chassis control. The OE Match solid bushing provides factory-style fitment, exceptional durability and reduced suspension deflection, helping to deliver sharper handling, improved stability and the precise driving characteristics expected from your Porsche.

Rear axle spring plate mount.
Porsche reference no: 477501089

These thrust bearings are a welded steel construction with electrogalvanized and powder coated finish. They connect the rear axle tube to the body. After the years, the original thrust bearings are usually worn out and porous. There are no original replacements, and thus an overly spongy rear axle is a problem on many 924-968s.
This rigid version is suitable for both street use and motorsports.
Its advantages:
• Wearless design
• More directly guided rear axle and therefore less spongy handling.
• Elimination of rumbling noises due to worn out rubber thrust bearings.
• Excellent build quality
Thanks to the design, installation is possible without removing the rear axle!
