The Genuine Porsche 9995913900C clamping washer, replacing 99959139002, is an OE 5.0 mm clamping washer used in the rear spoiler / rear aerofoil assembly on selected Porsche 993 Carrera S / C2S / C4S models. Sold individually, this washer helps secure rear spoiler components correctly and is ideal for spoiler repair, bodywork restoration or replacing missing original hardware.
What This Part Does / Functions
• Secures rear spoiler / rear aerofoil components
• Acts as a clamping washer for 5.0 mm fixing points

• Supports correct factory assembly of the rear spoiler system
• Helps prevent loose fittings, rattles or movement in the spoiler area
• Provides OE Porsche fitment for the original rear spoiler hardware
