The rear end of the Serpent S400 has been designed for high
performance and ease of maintenance. The rear bearing blocks have been
designed in 2 pieces which allows the topside to be simply removed with
4 screws, giving you easy access to the differential for maintenance or
adjustment. All the parts have been machined from aluminium and have
anodized in gun metal grey.
The rear end of the S400 features strong 1-piece lower wishbones and
aluminium uprights. As with all the wishbones on the car, the lower
wishbones can be used on both the left and right sides, minimizing the
number of spare parts needed to bring to the track. The rear upright
features a pivot pin mounting point on the bottom and three upper camber
link mounting holes for fine-tuning camber rise.
The kit version of the S400 comes supplied with a lightweight and
smooth rear ball differential. The diff halves are made from hard
anodised aluminium which is lightweight yet extremely strong, while the
use of high quality balls and steel plates ensure a long lasting and
smooth diff action.

The
S400 drive train utilizes a 2-belt system with rear ball differential
and front spool, while 4 CVD (constant velocity drives) transfer the
power to the wheels. The motor, which is mounted to an aluminium
plate, powers the main spur gear and hard anodised aluminium pulleys.
Similar to the rear suspension in configuration, the front suspension
sports a lower composite wishbone while the upper camber adjustment is
handled using a track rod which is solid, lightweight and can easily
handle impacts.
A standard system on all high-end touring cars, the S400 features a
front C-hub system, which is a lighter alternative to a pivot ball
steering system. The car comes standard with a 4-degree caster block
but is also supplied with a pair of 2 and 6-degree blocks.
The servo saver on the S400 features 4 steering rod mounting points
to allow the user to easily adjust the cars Ackerman. The servo saver
system itself features a nut for adjusting the spring tension of the
saver.
The chassis plate has been machined from a plate of 2.5mm thick
carbon fibre, which creates a perfect platform for the cars
electronics as well as stiff structure, especially when combined with
the equally rigid 2.5mm thick carbon fibre top deck. All holes in the
base of the chassis have been countersunk while on the top of the
plate, the area around the motor has been milled down to allow it to
sit as low as possible. The plate features cooling holes below the
motor and speed controller.

The S400 is supplied with colour coded anti-roll bars front and
rear that are held in place using a 2 piece anti-roll bar mount. The
anti-roll bars are available in a number of thicknesses and are
connected to the wishbones using short adjustable track rods.
Stiffness is quickly and easily adjustable by changing the linkage
mounting points on the lower wishbones or alternatively by changing
the position of the ball joint pivot point on the roll bar itself.
The RCC shock absorbers are the smoothest and easiest to build
shocks ever designed. Machined from aluminium and unique in that the
shock bodies only open on the bottom half, they are really simple to
assemble. The result is an ultra-smooth and air-free shock absorber
thanks to the self-bleeding system incorporated into the design. The
shocks are supplied with 4 different shock pistons.
Another great benefit is that these shock absorbers come pre-assembled
in the kit, so you need only add shock oil.
The car comes supplied with a front spool which has been made from
hard anodised aluminium while its shape has been optimised to ensure
that the part is as light as possible without compromising strength.
The drive is provided through the attached pulley into the lightened
steel drive cups, which are held in place using steel pins.
