This product is a sheet-metal support component that fits behind or within the outer rocker panel area on Porsche 356 models. It is made to fit as a replacement support structure where the original factory metal has corroded, been damaged.
Fits:
Porsche 356 - 356C
This Rocker Panel Support is widely used in classic Porsche restoration work, especially on Porsche 356 and often applicable alongside other sill and rocker panel components. Always confirm fitment depending on your specific year/model and the extent of your structural repair needs.
Rocker panel support areas on older Porsche vehicles are prone to rust and corrosion, often due to their location near ground spray and moisture ingress. Failing metal in this area can significantly weaken the vehicle’s structural integrity, affect door and panel alignment, and lead to further sheet-metal failure. Installing a proper support panel restores strength and acts as a foundation for additional bodywork, ensuring long-term durability and safety during restoration.
Replace this rocker panel support when:
• The original metal is rusted or perforated
• Previous repairs have deteriorated
• The outer rocker panel is warped or misaligned
• You’re performing a full body restoration
