The rest of the bodywork is entirely bespoke, with a stretched wheelbase and widened wheel arches, both of which sit on lowered springs and new 18i BBS alloy wheels.
The body itself is all carbonfibre and punctuated by aero-optimised fins and larger air intakes on the front wheel arches, as befits its track remit. The exterior mirrors have also been ditched for electronic screens fed by a trio of cameras mounted on the body.
Towards the rear, it shares design elements with past Porsche racers. For example, the bumper-width rear wing takes influence from the seven-time Daytona-winning Brumos Porsche 935/77, and its vertical spoiler supports are said to be reminiscent of the Porsche 962 Le Mans racer. To reduce weight, it does without grille covers and certain panels, leaving components such as the exhaust open to the elements.
More weight-saving measures have been made inside, with the removal of the front and rear passenger seats and air conditioning system.
It also gets a plaque denoting which model number the customer has chosen, two monitors to replace the door mirrors, colour-adjustable ambient lighting and an FIA-spec roll cage.
It will be launched with a choice of seven colours, including Star Ruby, Signal Orange, and Agate Grey Metallic (brand new for the 911 range).
