(from Aston Martin
Press Release) From July, Aston Martin will offer the
option of a factory-fitted "Sports Pack" specification for the DB9
Coupe, combining revised suspension characteristics with a new alloy
wheel design to give subtly different driving dynamics.
The new five-spoke forged aluminium alloy wheels are lighter than
the standard wheels, the springs and front anti-roll bar are
modified and the ride height lowered.
Taking the DB9’s VH architecture as its foundation and retuning some
of its key components, the DB9 Sports Pack offers an even more
focussed driving experience, with improvements to both high-speed
body control and steering response. That means a DB9 Coupe
specifically for the enthusiastic driver with a high level of
driving skill, who likes to drive quickly, safely and with
The first key to the sharper dynamic balance is a significant
reduction in ‘unsprung’ mass which indirectly allows the suspension
to react more quickly to inputs such as bumps and cornering forces -
resulting in improved grip, steering response, body control and ride
With the DB9 Sports Pack, each five-spoke light alloy wheel gives an
unsprung weight saving of more than 1kg, with a small but
significant additional saving from the use of titanium wheel nuts.
In total, that equates to more than five per cent reduction in
unsprung weight on each corner of the car. The new, lighter 19-inch
wheels are the same size as the standard wheel and use the same
The DB9 Sports Pack’s spring rates are increased by 68 per cent at
the front of the car and 64 per cent at the rear. The front
anti-roll bar is modified, and the dampers are revised to support
the new spring and anti-roll bar characteristics. Together, the
changes optimise body control and front-end grip without
compromising ride quality or adding weight. The ride height is
reduced by 6mm, lowering the car’s centre of gravity and further
reducing body roll while leaving ample ground clearance and backed
up by modified bump stops.
The composite undertray is also replaced, by a load-bearing
aluminium panel that performs the same function in managing
underbody airflow while adding further structural stiffness, to
resist larger lateral loads fed into the front of the car by the
uprated front springs and anti-roll bar.
The cumulative effect is significantly improved dynamic response,
and especially steering feel - making the DB9 feel lighter, more
positive on turn-in, more agile and more involving for the
enthusiastic driver. Body control is especially enhanced during high
speed manoeuvres, giving the DB9 a more neutral handling feel.
Aston Martin Sales & Marketing Director, Bill Donnelly, says: “This
optional Sports Pack will offer driving enthusiasts the opportunity
to tailor their DB9 Coupe to deliver an even more rewarding dynamic
experience. The Sports Pack offers another addition to the Aston
Martin range and provides customers with an even greater choice and
the ability to further personalise their DB9.”
