The interior door panels including speakers, airbags and door handles have been removed to reduce weight. We have retained the glass windows, and electric motors.
Custom panels have been cut to fit using a plywood template before cutting out carbon fibre sheet. A light weight aluminium door handle and pull strap to open the door are also fitted.
A master battery cut-off switch is needed. The location conveniently next to the battery is taken up by the Air Conditioning drier and alarm siren which had to be removed. The aircon system was then drained and the drier and pipework removed, reducing weight further. The switch is in-line with the battery positive terminal and mounted on a bracket. It is activated by one of two pull switches which will run back to the interior dashboard and up to the scuttle tray under the windscreen. The latter allowing track marshals to activate the switch from outside the car.
