This OE Match eccentric bolt is a critical suspension component designed to Porsche factory specifications. Installed at the junction between the rear trailing arm and the spring plate, it features an offset (eccentric) cam design that enables fine adjustment of suspension geometry.
The bolt typically measures M12 x 1.5 and is engineered for durability under constant load and stress.
By rotating the eccentric section, technicians can precisely adjust rear camber (and in some cases toe), making it essential for proper wheel alignment. This makes it a key component during suspension setup, maintenance, or restoration of air-cooled Porsche 911 models.
This eccentric bolt allows accurate adjustment of the rear suspension alignment by altering the position of the trailing arm relative to the spring plate. It ensures optimal camber settings, which directly impact handling, tyre wear, and vehicle stability.
Function
• Enables precise rear camber adjustment
• Connects trailing arm to spring plate securely
• Maintains correct suspension geometry
• Helps optimise tyre contact and wear
• Supports stable handling and driving performance
Eccentric bolts are subject to corrosion, seizure, and wear over time, especially due to their exposed position in the suspension. A seized or worn bolt can prevent proper alignment adjustments, leading to uneven tyre wear and compromised handling. Replacing it ensures accurate alignment, improved safety, and optimal suspension performance.
When to replace
• Bolt is seized or difficult to adjust
• Visible corrosion or thread damage
• Inability to achieve proper wheel alignment
• During suspension rebuild or overhaul
• Uneven tyre wear or handling instability

This OE match adjustable spring plate is a direct replacement for the original Porsche component used on 911 models equipped with the 915 gearbox. Engineered to original specifications, it integrates seamlessly into the torsion bar rear suspension system. Unlike fixed spring plates, this adjustable version allows precise ride height tuning via an integrated adjustment mechanism, eliminating the need for repeated torsion bar re-indexing.
Sold individually, 2 required per vehicle.

Unfortunately, lowering the rear of your 911/912/930 is not nearly as easy as lowering the front. That is until you install this new Adjustable Spring Plate kit Now your rear ride height can be adjusted to your desired level with a simple turn of a bolt.
Note: When using adjustable spring plates with stock torsion bars, the splines may be a tight fit and require a small amount of hand fitting.
Spring plate normally rust, replacing them will give you a better ride.

Gain back ride quality and rear end stability with High Density Rear Spring Plate Bushings for your 911. Under prolonged use, especially when driven hard, the OEM bushings can break down allowing more slop in the rear suspension. If neglected long enough or driven under heavy load enough, these bushings will eventually deform allowing the spring plate to contact the cover plate. Replacing your factory bushings with our 25% stiffer units will allow full and smooth articulation of the spring plate, thus improving the ride quality and performance of the legendary rear end in your classic 911. Featuring a higher, "sport" durometer these rubber mounts are a great compromise between soft factory mounts and solid/spherical bearings often used to replace them.

OEMatch Spring Plate — Fit, Function, Confidence
Spring plates form a key part of the rear suspension on many Porsche models, linking torsion bars to trailing arms to control ride height, preserve alignment and manage suspension travel under load. OEMatch focuses on Porsche applications and catalogues over 4,000 part numbers and extensive cross-references to support repairs and restorations.
Understanding OEMatch Spring Plate
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original spring plate.
OE (Original Equipment) refers to parts matching original specifications for the spring plate and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM spring plate engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. In operation, a spring plate provides a pivot between torsion bar and trailing arm, helps maintain rear wheel alignment as the suspension moves, and contributes to stable ride height and handling balance. Plates are typically formed from high-strength steel or alloys and use bushes or bearings at mounting points to control movement.
Benefits Include
- Restores correct rear suspension geometry and alignment for consistent handling.
- Maintains ride height and reduces unwanted rear-end movement under load.
- Available in fixed and adjustable designs to suit restoration, service or performance use.
Why Spring Plate Wear and Fail
- Corrosion and rust that weaken the plate or mounting surfaces.
- Worn bushes or mounts producing excess play and vibration.
- Fatigue cracks from repeated torsional stress.
- Impact damage from road hazards or improper installation.
The Importance of Replacing with OEMatch Spring Plate
Replacing worn or damaged spring plates restores suspension geometry and alignment accuracy, reduces vibration and noise, and helps retain predictable handling on road and track. Proper replacement also protects related components such as trailing arms and torsion bars by removing excessive movement and restoring specified clearances, which supports safe and reliable vehicle behaviour.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances for Porsche models.
- Adjustable and performance variants available where correct ride-height or alignment tuning is required.
- Suitable for classic restorations, routine servicing and track-focused preparations.
