The VTBi bracket system is designed to tuck under the seat to give a minimum footprint, this aids fitment into narrow and restricted cockpits. The VTBi brackets are made from 3mm thick black powder coated steel, with a revised edge profile which helps avoid the leg bulge.
The brackets allow the seat to be tipped, raised and lowered using the various hole and slot combinations. This bracket has additional lower slots for changing leg length position.
They will fit to the Tillett STRi and PTRi seat adjustment runners as well as other runner brands. The VTBi can be used directly on the factory Mazda runners of the Mk1 and Mk2 MX5 cars.
