Recreate the strength and accuracy of the original bodywork with this Metro 6R4 Offside Sill. Manufactured from GRP (fibreglass), it delivers the authentic fit and appearance needed for high-quality Group B restorations or competition builds.

Each sill is hand-laid and finished to a smooth surface ready for primer and paint. The GRP construction provides excellent rigidity while staying lightweight and completely corrosion-free. As a result, it’s a practical and durable upgrade from traditional steel panels.

In addition, the offside sill aligns perfectly with OEM mounting points and adjoining panels such as the floor pan, door aperture, and rear arch. Designed for easy installation, it ensures precise body alignment and consistent quality across your build.

Moreover, this panel is part of our complete Metro 6R4 GRP bodywork range, allowing you to replace every major exterior section with lightweight, long-lasting components. Combine it with the Metro 6R4 Nearside Sill and Front Arch Panels  for a seamless and professional result.

🔧 Installation Tips

Trial-fit the sill before painting. Use bonding adhesive or rivets for installation, and apply seam sealer for a clean, watertight joint. Because GRP is light, apply even pressure to maintain alignment.

Finally, explore the Metro 6R4’s Group B history and engineering legacy on the FIA Historic Rally Championship website for authentic technical references and photos.
