Product Details

The STBi bracket system is designed to tuck under the seat to give a minimum footprint, this aids fitment into narrow and restricted cockpits. The STBi brackets are made from 5mm thick black powder coated aluminium, 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 STBi can be used directly on the factory Mazda runners of the Mk1 and Mk2 MX5 cars.

Features
1. Factors to consider

There are many factors to consider when choosing a new kart seat.
If you have had a seat in the past. Do you know the size and shape?

2. Choose a Shape

Shape does not make as much difference as the teams would have you believe, but they will be nervous of miss positioning the seat and may want you to use the shape they are used to fitting.

This is fine until the seat is not the right fit for you. An ill-fitting seat can cause a driver to damage their body or hang on the wheel, neither are good for ultimate performance.

Different shapes put in the chassis with the drivers back in exactly the same place, made with the same materials will pretty much handle the same.
That said a significant angle change of the back will alter the handling especially for bigger driver and this should be looked at separately.

The STBi bracket system is designed to tuck under the seat to give a minimum footprint, this aids fitment into narrow and restricted cockpits. The STBi brackets are made from 5mm thick black powder coated aluminium, 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.
