The STBT bracket system is designed to raise the driver by a additional 60mm compared to the STBI or STBO.
The STBT bracket is needed for regular saloon cars, which require slightly taller brackets in order to sit at the correct position.. They are made from 5mm thick black powder coated aluminium and allow the seat to be tipped, raised and lowered using the various hole and slot combinations. The lower slots in the base of the bracket enable them to fit directly on the Tillett STRO and PTRO seat adjustment runners.
The optional aluminium “Pegged spacer kit” can also be used in these brackets to strengthen the front slots in the event of an accident.
