PLM Bottom Mount Adapter Plate – For Low Down Seat Rails

PLM Bottom Mount Adapter Plate – For Low Down Seat Rails

SKU: PLM-BS-AD

The PLM Bottom Mount Adapter Plate is designed to convert PLM Low Down seat rails from side-mount configuration to bottom-mount compatibility. This allows you to run bottom-mounted racing seats while maintaining the strength and low seating position of your existing PLM rails.

Constructed from high-strength steel, these adapter plates are built for durability and rigidity. Unlike thinner brackets that can flex or bend, PLM brackets are engineered to withstand heat and stress without warping—making them ideal for performance and track applications.

Installation is straightforward, attaching to the rails using eight simple nuts.
