The TB108 is an aluminium side mount from Tillett. Part number TB108. Black finish.
Side mounts bolt to the sides of the seat shell and connect it to the fitting frame or floor-mounted subframe. Side mounting positions the seat lower and further from the centre tunnel than a base mount does, and gives some control over seat angle through the choice of bolt holes on the bracket.
Tillett’s side mount bolt pattern varies between shell models and between older and newer versions of the same model. The TB108 does not carry a listed compatible-seat attribute, so confirm the fit for your specific shell before ordering. Send us your seat model and shell year and we will check. A bracket that does not match the shell pattern will not fit, and it is easier to verify before buying than after.
Aluminium construction keeps the bracket light relative to an equivalent steel mount.
We have been stocking the full Tillett range since 2003. If you have a fitment question about the TB108 and your shell, give us a call or drop us an email with the seat details and we will sort it.
Will this fit my seat and car?
Mounting hardware is specific to the seat pattern and often the car, so match the product name to your exact seat, and tell us the car and seat model if you are in any doubt. Our guide on the bucket seat fitting stack shows where each part sits.
Do I still need a sliding runner?
Only if you want fore-and-aft adjustment: the runner sits between this hardware and the seat or floor depending on the stack. Our sliding runner guide explains the options and widths.
Tillett seats are custom-made to order
These carbon seats are handcrafted in the UK for each order. We do not stock or display them in the showroom, so everything is a special order placed with Tillett when you buy.
Lead times depend on the model and the options you choose, so ring us before ordering if you are working to a date.
Special order
Because each seat is made for you, our special order terms apply once production has begun.
Tell us your height, weight and the car, and we will confirm the right size and mounting before anything is made. Tillett sizing is specific and worth getting right first time.
