The B7 is a lightweight, high specification version of the B6 Screamer. It has the narrowest dimensions of any FIA 8855-1999 homologated seat and at 3.7 kg also the lightest available to the best of Tillett’s knowledge.
This is the B7-40 which has a maximum width of 40 cm. This narrower 40 cm version is for cars where there are fitment issues and a narrower seat is necessary. The two models are otherwise the same size internally and are both homologated.
The seats can be ordered with Dinamica® panels as an option, which adds 1 kg.
There are four bracket options to use for installing the seat:
- TB FIA mounting brackets which have been tested with the seat. These brackets are immensely strong and beautifully machined and recommended as the install method.
- TB F1 brackets are made from 6 mm thick anodized aluminium and point inwards under the seat.
- TB F5 brackets are made from the same 6 mm high grade anodised aluminium like the TB F1 but which point outwards away from the seat.
- TB5 is a powder coated 5 mm thick aluminium version of the outward pointing TB F5.
