Developed using Tuthill Porsche's extensive motorsport
expertise, the adjustable spring plate provides exceptional strength, corrosion
resistance and long-term durability. Whether you're setting up a fast road
Porsche, historic rally car, track machine or concours-quality restomod, this
component delivers the precision and performance expected from one of the
world's leading Porsche specialists.
Designed to work with the factory rear torsion bar suspension, the adjustable spring plate simplifies suspension setup and enables fine tuning without repeated torsion bar re-indexing.
Kit Contents• 2 x titanium spring plates
• 1 x set of Superflex bushes
• 1 x bolt kit
Designed to improve chassis response and suspension adjustability, these lightweight spring plates allow precise suspension tuning while reducing unsprung weight compared to factory steel components.
The adjustable design enables fine ride height and suspension geometry setup, helping optimise handling balance, corner weighting, and overall driving dynamics.
Weighing just 2.58kg compared to the original steel spring plates at 4.2kg, this upgrade delivers a substantial reduction in rear suspension weight while maintaining outstanding durability and rigidity.
Ideal for enthusiasts seeking a lightweight motorsport-inspired suspension solution for classic Porsche 911 builds.
