Recreate the iconic Group B look with this Lancia Delta S4 Front Arch (Offside). Manufactured in GRP (fibreglass), it faithfully replicates the original arch profile and mounting geometry of the Delta S4. As a result, it delivers precision fitment and the lightweight durability that made the S4 a rally legend.

Each panel is hand-finished with a smooth surface ready for primer and paint. Because GRP is corrosion-free and easy to work with, it reduces prep time while maintaining the strength needed for rally conditions. In addition, it aligns accurately with factory mounting points and the matching front wing sections, making installation straightforward.

Moreover, this front arch pairs perfectly with our Nearside Front Arch and Rear Arch Panels to complete your body set. Whether you’re building a competition car or restoring a Stradale, these panels ensure consistency and quality across your project.

🔧 Installation and Preparation

Before painting, test-fit the arch to confirm alignment. Use bonding adhesive or rivets for secure mounting and apply flexible seam sealer to finish joints. Because GRP is lightweight, apply even pressure when fastening to maintain the panel’s shape.

Finally, discover the Lancia Delta S4’s engineering and competition heritage on the FIA Historic Rally Championship website  for official Group B archives and technical insight.
