XJR15 for JaguarSport

Customer supplied central carbon fibre honeycomb tub and exterior body panels. ARRC developed chrome-moly tube chassis to integrate with tub and provide backbone structure to mount engine, gearbox, rear suspension, front suspension and steering.
Overview of gearbox and rear suspension. Audi gearbox with cable operated shift mechanism designed and built by ARRC. Late model XJ6 rear uprights are modified to attach fabricated wishbones  by ARRC. Adjustable rear anti-roll bar by ARRC.

Removable cross member provided to allow for easy gearbox removal.

Note that drive shafts were not installed at the time of this picture.

Front and rear bodywork hinges designed to allow easy access to front suspension and engine/gear box.
Oval plates on the inside of the rear bodywork are wing mounts. When the bodywork is closed these rest on oval cups allowing the down force to be fed into the rear chassis.
