Genuine Porsche 996-343-511-01 Coil Spring Shim 6.5mm Compensating Plate

The Genuine Porsche 996-343-511-01 is a precision-engineered coil spring shim, also known as a compensating plate or spring seat, designed for Porsche 911 (996/997), Boxster (986/987), and Cayman models. This OEM component is a critical suspension element that ensures proper ride height and geometry.

Key Features:

• 6.5mm thickness compensating plate for precise suspension tuning
• Metal washer-style plate that sits between the coil spring top and strut mount
• Compensates for spring manufacturing tolerances to achieve factory-specified ride height
• Ensures correct suspension geometry and alignment settings
• Genuine Porsche OEM quality with precise fitment
• Used as necessary to attain correct ride height per factory specifications

This compensating plate is essential during suspension service, spring replacement, or when correcting ride height issues. Porsche marks springs with tolerance codes, and the correct shim thickness (3.0mm or 6.5mm) must be selected to maintain the intended static height and optimal handling characteristics. Installing the incorrect thickness or omitting the plate can shift ride height by several millimeters and adversely affect camber and handling performance.
