Race Door Panels & Master Switch

Door Panels
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.

Master Switch
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.

Track Modifications

After a long gap at the end of 2010, we embarked on the track / race modifications needed for the Boxster.  New brake discs / pads have been purchased, adjustable suspension and lightened race wheels ordered.  The latter two are built to order and on long lead times.
In the mean time a number of smaller, but important track modifications have been progressed.

Bonnet Pins
The electrically operated bonnet and boot locks have been replaced and aluminium bonnet pins fitted.  The pins were mounted through the boot inner and holes drilled in the bonnet. for the surface catches.  These are required on the track to prevent the bonnet flying open.  We've retained the hinges and gas struts to keep it easy to open the bonnet and boot lid.

Induction Kit
The stock air filter housing and filter have been removed and replaced with a power induction kit in the form of a cone shaped filter, and aluminium heat shield.  This ensures cold air is taken from the air scoop on the side of the body and prevents hot air from the engine bay. being inducted. This typically provides ~10bhp increase.  The plastic housing of the original filter was fitted before the engine in the factory, it therefore had to be cut out in pieces which was quite a job.
