The STBI bracket system is designed to provide a minimum footprint by being placed under the seat. It makes it easier to fit into narrow and restricted cockpits. STBI brackets are manufactured from 5mm thick black powder-coated aluminum with a revised edge profile that helps prevent leg protrusion.

The brackets allow the seat to be tilted, raised and lowered using various combinations of holes and slots. The bracket has additional lower slots to change the leg length position.

Designed to accommodate Tillett STRI and PTRI seat adjustable rails and other rail brands. STBI brackets can be used directly on the factory Mazda rails of Mk1 and Mk2 MX5 cars. Thanks to these features, the STBI bracket system appeals to a wide range of uses.
