At its most basic the Mk III Series C is nearly identical to the Mk III in terms of its layout. At the front, a slanted nose houses a radiator fed air from a vent above the front splitter, and exiting over the top of the bodywork just in front of the cockpit. The sidepods are straight and flat. 

An engine intake is mounted behind and above the cockpit. Also shared with the Mk III is the use of a steel tube frame and carbon fiber chassis.

Some notable changes to the design of the Mk III for the Mk III C were concentrated on the cockpit and nose areas. The standard roll hoop is positioned immediately behind the drivers seat and integrates the intakes for the engine. The front of the cockpit is also redesigned, as an aerodynamic windshield was added immediately in front of the driver.

The nose of the Mk III C is notably more rounded than the Mk III. The front fenders are no longer square, and taper as they extend to the front splitter. The headlights are also redesigned, including four lights instead of the previous two. The exits for the radiator are also designed to run the full width of the nose, the openings were now slimmer than they had been on the Mk III. A new addition is further ducting located on either side of the cockpit designed to allow air from the front diffuser to exit upwards and over the top of the bodywork. The bodywork in general is also lower on the Mk III C, with exception of the vehicle's fenders.

Mechanically, the Mk III C's transmission is a major improvement from the older car. A new 6-speed gearbox built by X-Trac is part of the package, replacing the previous 5-speed. This gearbox is further enhanced by the option of a pneumatically actuated gear change system developed by Megaline which is activated by paddles behind the steering wheel, rather than by a traditional gear stick.

LE MANS 2003

The MkIIIC was a long time in coming.  The original MkIII has been an outstanding customer chassis, its resume speaks for itself:  41 victories in 87 starts.  The beauty of that chassis was its simplicity, a steel tube frame with a push-rod V8 clothed in high downforce bodywork. 

The MkIIIC continues on that theme, simplicity &  with the addition of carbon fiber the overall stiffness of the chassis is increased by 40%.

The MkIIIC's suspension is unique for its "Riley Rocker" arrangement of the spring and damper.  Typically the spring/damper are combined into one unit.  The Riley Rocker splits the two units which makes adjustments easier (allowing for pit lane adjustability) as well as the giving the engineer the ability to make adjustments to one that does not effect the other.
