The STBT bracket system is designed to raise the driver by an additional 60 mm compared to STBI or STBO. The STBT bracket is required to fit in the correct position, which requires slightly longer brackets than required for regular sedans. Made of black powder-coated aluminum, the bracket provides durability with its 5 mm thickness and allows the seat to be tilted, raised and lowered with various combinations of holes and slots. The lower slots at the base of the bracket allow them to be attached directly to the Tillett STRO and PTRO seat adjustment rails.

Optionally, the "Pigment spacer kit" made of aluminum can also be used in the brackets to strengthen the front slots in case of an accident. It aims to better protect the driver in case of an accident by providing extra security.
