Lotus Service Notes
- At each side, two screws pass through the transom end flange into captive nuts in the body side panel.
Rear Scuttle Panel
The rear scuttle panel is fixed at each side by two horizontally disposed M6 screws into bond nuts on the
body side panel, and is bonded along the top edge of the rear bulkhead.
Body Side Panel
The body side panels are secured by screw fasteners for ease of access and replacement. Each panel
is retained as follows:
- The top edge of the body outer side panel lips over the body inner side panel, to which it is fixed with four
screws engaging with captive nuts in the inner panel.
- A single screw passes from beneath, through the end of the rear bulkhead capping rail into a captive nut
in the side panel.
- The lower edge of the body side is secured to four threaded inserts in a chassis extension flange.
- At the front of the rear wheelarch, two screws secure the side panel baffle/stiffener to a vertical angle
bracket bolted to the main chassis rail.
- At the rear end of the panel, two screws pass from beneath, through the rear transom flange into captive
nuts in the body side.
- At the front of the body side, two screws pass upwards into captive nuts in the rear end of the front body
panel.
'A' Panels
At the front of each body side, a separate 'A' panel is used to form a duct for air exhausting from the front
wheelarch. Each panel is secured by four screws at the top (2 into the body side, 2 into the front body panel),
and 2 screws into the body side sill at the bottom.
Front Quarter Panels
A front quarter panel is fitted ahead of each front wheel and forms a mounting and duct for the oil cooler,
as well as tying the front corner of the body to the splitter panel. The quarter panel is fixed by:
- 2 screws from beneath, through the splitter into captive nuts in the quarter panel lower flange.
- 2 screws down through the front body flange into captive nuts in the quarter panel upper flange.
Front Wheelarch Shields
A small moulded plastic panel is fitted within each front wheelarch, fixed between the body side and radia-
tor mounting panel, and provides protection for the cooling and brake system components.
Front Undertray
An alloy sheet undertray is fitted beneath the nose, and stabilises the front body, splitter panel, and crash
structure to the front of the chassis. The undertray is secured by:
- 3 screws into the front edge of the chassis (also slots into the extrusion).
- 3 screws and nuts at each side into the lower flange of the crash structure.
- 5 fixings around the front edge, passing through the splitter into captive nuts in the front body flange.
- 2 screws and nuts to a central support bracket from the crash structure.
- 1 screw each side to the splitter panel.
Front Splitter Panel
A flat timber composite splitter panel is mounted beneath the nose to cleanly split the airflow above and
below the underside of the car to optimise aerodynamic downforce whilst minimising drag. A road and race
version of the panel are designed to balance the forces produced by the two types of rear aerofoil. Note that
the front splitter panel is constructed from timber composite, sealed by a layer of resin, and that the occasional
grounding of this panel, which is a normal occurrence under track conditions, will cause erosion of the outer
layer, requiring periodic repair or replacement.
The panel is secured by:
- Undertray fixings as listed above.
- 2 screws at each side to the front quarter panel.
