The washer sits within the rear shock absorber mounting assembly and helps evenly distribute clamping force between the shock absorber, mounting hardware, and supporting plates.

Its role is essential in maintaining:
•   Correct shock absorber positioning
•   Stable suspension mounting geometry
•   Reduced stress on suspension components
•   Proper load transfer through the rear suspension system

This small component plays an important role in ensuring reliable suspension operation under both normal driving and high-performance conditions.

Functions & Technical Role
•  Load distribution: Spreads mounting force evenly across the suspension assembly
•  Mounting support: Helps stabilise rear shock absorber mounting components
•  Suspension alignment: Maintains correct rear strut positioning

•  OEM precision: Manufactured to Porsche factory specifications for exact fitment and durability

Fitment / Position on Car
•  Fitting position: Rear suspension
